Interdimensional War

The Interdimensional War is a prolonged engagement between the Astral World and the Barian World, with Earth caught in the middle. It ultimately serves as the main conflict of Yu-Gi-Oh! ZEXAL. The Numeron Code is the ultimate objective of both sides as it decides the victor and fate of all three worlds.

In the Beginning...
According to Ena, Barian World and Astral World were once one single world. It was during the time when "The Power of Chaos" existed in their world, thousands of years ago. The people of that dying World believed that they could Rank-Up if they just threw away "Chaos" from their world. So, any soul with Chaos was banished from their world eventually creating the Barian World.

Now, Astral World is a world were nothing bad exists, not even hatred. It's a pure, clean world. But without "The Power of Chaos" it simply became weaker due to losing this power. Now Astral World has become a place that exists only to Rank-Up.

And this resulted in the creation of "Eliphas", the will of Astral World and a being whose only aim is to Rank-Up.

Astral vs. Don Thousand
THe emissary of Astral World, Astral fought against the god of the Barian World, Don Thousand. According to Jinlong, two divine lights were fighting in sky far, far away. The battle lasted for hundreds of days. Rains of fire poured down on the grounds as lightning ripped through the very Earth. Then those two lights collided and vanished. Astral ultimately emerging victorious, sealing Thousand in the Sea of Ill Intent, but brought chaos to the Earth in the process. Also, during the battle, a shard of Thousand's malice was trapped inside Astral. It eventually developed into the form of Number 96, which was the embodiment of the power of a "Forbidden Number".

Past Lives
It is revealed that before becoming Barians, the Seven Barian Emperors were human once in their past lives, with each of their past being connected to each ruin the Legendary Numbers were hidden in, along with the numbers themselves and their protectors.

The Missing Barian Emperors
The leaders of the Barian Emperors, Nasch and Merag, went missing at some point. According to Thousand, Vector is the one responsible for their disappearances, as he murdered them.

Prelude
Not much is known on how the war between the two dimensions really started, with the only clue being said from Dumon and Mizael that one cannot exist while the other survives. Recently, it may have been ignited due to the Barians' grudge against Astral World for their banishment.

Worlds
These are the worlds that are caught up in this vast conflict for the Numeron Code.



Astral World
The dimension where Astral was born and a counterpart of Barian World. Barian World and Astral World were once one single world. It was during the time when "The Power of Chaos" existed in their world, thousands of years ago. The people of that dying World believed that they could Rank-Up if they just threw away "Chaos" from their world. So, any soul with Chaos was banished from their world, eventually creating the Barian World.

Now, Astral World is a world were nothing bad exists, not even hatred. It's a pure, clean world. But without "The Power of Chaos", it gradually became weaker due to losing this power. Now Astral World has become a place that exists only due to Rank-Up.

Participants
These beings has made their contributions in the conflict:

Astral

The emissary of Astral World, sent from the Astral World to Earth to obtain the Numeron Code before the Barians do. The Code was an all-powerful card that created reality and could decide fate. He also has a secondary objective of destroying the Barian World. Upon arriving in Yuma's world, his memories were scattered in the form of the 100 "Number" cards. While originally he only retained one of the Numbers, he knew that when two or more Numbers confront in a Duel, they will battle each other to consume one another, allowing Astral to absorb vanquished Numbers and regain pieces of his memories. With the of his new friend, Yuma Tsukumo, they have regained 59 pieces of Astral's memories, while collecting 55 of the actual Numbers, with the addition of seven Chaos versions.Later, he returned back to the Astral World after suffering critical injuries from the vicious rematch against Number 96. Currently, Yuma and Eliphas are dueling to determine Astral's fate.

Rainbow Kuriboh

A monster that Yuma recognizes as one of his father’s monsters. It is Yuma's new aid and guide that has protected him from Eliphas' wrath. It now currently assist Yuma in his battle against Eliphas, to save Astral.

Eliphas

Ena



Barian World
The counterpart dimension of Astral World that is ruled by the Seven Barian Emperors and is seemingly full of malice. Long ago the Barian World was once part of Astral World and was created with the purpose of hosting any soul that possessed the power of Chaos.

Participants
These beings has made their contributions in the conflict:

Don Thousand

The god of the Barian World and the central antagonist of this conflict. Don Thousand battled Astral thousands of years ago and lost, being sealed in the Sea of Ill Intent, but was released by Vector, who offered Don Thousand his life in exchange for the power to defeat Yuma and Astral as his hatred for them grew.

Seven Barian Emperors

Vector

Vector was the first of the Barian Emperors revealed during the battle with Faker when he possessed him, he only appeared as a red devil-like energy being at first. Not long after the battle he took on the form of a human named Rei Shingetsu and became an ally and friend to Yuma, a part of his master plan. He initially acted very clumsy and poor at dueling but showed his true prowess when he gave Yuma "Rank-Up-Magic Limited Barian's Force" and the V Cards in order to gain his trust.

When "Rei" was kidnapped after his second duel with Vector Yuma went to rescue his "friend" only to discover the deception. This nearly destroyed Yuma and Astral forever until they created Zexal II and defeated him once again.

Later Vector released Don Thousand and became his host, determined to help him to recover the legendary Numbers. Despite this he only appeared at the ruins that told the tale of his past life as a mad prince with Number 96: Dark Mist. The Legendary Number was claimed by Dark Mist and used against Astral. However the ruins were destroyed and Vector escaped with Dark Mist. Vector later appeared when Astral and Yuma dueled Number 96 who had since learned to control the chaos power within his body. He witnessed Astral return to the Astral World after being injured.

When Dark Mist's power returned to Don Thousand, Vector was shown to Thousand's palace and has since become his conduit to build more Barian Bombs in order to fuse Earth with the Barian World.

In his past life he was a Mad Prince who slaughtered his citizens because he believed he conspired against him, until he was the only one left. He eventually commited suicide as atonement for his sin. At some point in his life he attacked the Ocean Kingdom of the King Reginald Kastle and his sister Rio. He almost succeded due to summoning Abyss Splash the Ocean God, however Rio's sacrifice summoned another god and quelled Abyss. What happened next is unknown.

Dumon

The current leader of the Barians he initially didn't show himself to Yuma and his friends until they reached Sargasso but has been the brains behind the schemes of the Barians. He is generally obeyed and feared by Alito and Girag and they were the first two he sent to earth with Mizael shortly after.

He was shocked when Vector returned having assumed he was dead and even went to Sargasso with Mizael and Vector and ended up in a duel with Shark. Their duel did not last long before they turned to watch Yuma battle Vector. Their duel ended in a draw but not before Dumon noted some similarities between Shark and someone else.

After learning of the Legendary Numbers Dumon went to the first set, his own ruins ironically and even knew of the legend but could not explain why. His Barialapis was damaged keeping him in his human form. During Yuma's duel with Mach he translated the legend as he knew it. He even gave Yuma the advice to keep Utopia on the field and not destroy it as suggested by Shark. When Shark was about to fall Dumon caught him and helped him up but not before Shark somehow fixed Dumon's Barialapis and allowed him to regain his power. Yuma thanked Dumon before he retreated. A couple of times Dumon could be seen talking to Mizael about their past lives as humans and the ruins, and even about Nasch and Merag.

He followed Rio, who was possessed by Abyss, Shark, Yuma and Astral to the bottom of the ocean ruins, which were supposed to contain the memories of Nasch and Merag. He discussed the two missing emperors as well as the reasons that Astral and Barian World hate each other. Dumon seen the memories that show both Shark and Rio in the ruins memories as well as both himself and Vector strangely. Realizing their past lives were linked Dumon began to suspect that Nasch and Merag were Rio and Shark.

He later confronted Shark in the hospital and called him by "his" Barian name "Nasch".

Dumon was a knight in his past life who rode upon a Pegasus named Mach. They protected the land and a king however after they returned they were eventually killed when Dumon wouldn't attack the three renegade knights and Mach defended his master Dumon ending his life. Both of them were buried by the repentant knights after. However before his Death he appeared before his friend the King Reginald and tried but failed to save his sister from killing herself.

Girag

Girag was the first Barian to appear on Earth under the command of Dumon. He seemed quite happy for the task and used several schemes to try and take the Numbers from Yuma and Astral, even once taking control of Tori and Cathy. None of them worked however and in turn both Alito and Mizael were sent to assist. This continued until he received the Barian's sphere cube. He didn't like Alito's attitude to Alito dueling and the risks involved and so challenged Yuma with a large body of students.

When Alito interfered and caused his plan to fail he was angry but became concerned when he came back to find that not only had Alito lost the duel but was also badly beaten and needed to be healed. After this he challenged Yuma and "Shingetsu" to a duel in order to make them pay. He even put his life at risk by using "Number 106: Giant Hand" and the more deadly "Number C106: Giant Hand Red". When he was beaten he returned to Barian World for medical attention, and wasn't heard from again for sometime.

He eventually revived from some of Don Thousand's power. When he found the statue that looked like himself he soon found himself having an out of body experience as Ponta, the spirit of his friend from his past life had taken his body and thus he got Yuma to duel to get it back.Girag somehow remembered Ponta from his past life and even called out to him. Yuma won the duel but Girag burst out of the statue and swallowed Ponta's spirit and then returned to the Barian World, although it was shown that Ponta might still be alive.

In his past life Girag was known by Kiraku Souhachi and had Ponta, a Tanuki as his partner and body double on the battlefiend. However when they were about to lose a large battle Ponta was sent away in order to save his life, which caused him to resent Girag later. Girag was apparently killed and became a Barian.

Mizael

Mizael was the third warrior to go to Earth on assignment from Dumon, unlike Alito and Girag he was given the Barian's sphere cubes to use their Barian powers on Earth and with that he departed. He next captured his Over-Hundred Number, "Number 107: Galaxy-Eyes Tachyon Dragon" in a blank card.

After arriving on Earth Girag and Alito were given their Barian's Sphere Cubes from Mizael who then departed and began a ferocious duel with Yuma. Yuma fainted half way through from the Sphere Cubes power. Mizael then dueled Kite and gained a new rival due to their shared Galaxy-Eyes monsters.

Mizael was the one who came and recovered Alito from the human world and took him back to the Barian World to recover. He was also at Sargasso where he dueled Kite once again and even summoned his Number C monster which he couldn't do before. Their duel once again ended in a draw. After retreating he wasn't heard from again until he came across his own Number Ruin on Earth.

Mizael climbed the mountain to the ruin where he heard the roar of a familiar Dragon and hearing his own past life he refused to believe it and even attacked his old friend Jinlong. However the sky temple collapsed due to the power of both Neo Galaxy-Eyes monsters.

Mizael in his past life was a Dragon Tamer and had a friend in a Dragon known as Jinlong. The two of then protected a land until an event turned the village against them, which resulted in their deaths when they were attacked unaware.

Alito

Aito was the second Barian sent to Earth on the orders of Dumon after Girag but unlike Girag he didn't seem to want to go as he couldn't use his Barian Powers on Earth. He helped Girag with some of his schemes and even tried to go against Yuma fairly which Girag disapproved of since they could be seriously hurt themselves if they lost a duel.

Alito was different from the other Barians because he actually developed a crush on a human and actually had a sense of honor not seen in any of the other Barians, least of all Vector. He later dueled Yuma in order to get the Numbers but also to have a good duel with him as he had a firey passion that Yuma shared.

When Yuma won the duel Alito was seriously hurt but after he was hurt even worse and beaten by "Rei Shingetsu", who was Vector in disguise. After he was taken back to Barian World this was the biggest factor for Girag's rage against Yuma during his duel.

When Vector received the power of Don Thousand he accelerated Girag and Alito to heal quicker. Eventually they both awoke changed from before. Alito took the chance to visit his own Ruin which contained his memories and Number, Number 54: Lion Heart". He dueled Yuma with Nistro as his tag team partner due to the harmful effects of the Number. When he lost he retreated but was shocked as a flood of memories came back to him.

In his past life Alito was a powerful gladiator who fought with his bare hands, until he was falsely accused of a crime in order to stop the price he was supposed to battle from the possibility of losing. After this Alito was put to Death and eventually became a Barian.

Merag

Not much is known about Merag at the moment, although Dumon suspects that Rio may be her due to the memory he seen at the underwater ruins. The Number supposed to be tied to her is Number 94: Crystal Zero the Polar Ice Princess.

It is known that Merag was Human at one point but died and became a Barian, Don Thousand also said that Vector killed Merag and Nasch at some point in their lives even though Dumon suspects them of being alive.

Nasch

Like Merag not much is known about Masch, however Dumon suspects Reginald Kastle of being Nasch due to the memory he had seen in the ruins where Shark, Dumon, Rio and Vector were all in it and all, apparently still human. This is also supported by the crest that was on the Kastle family's old home and in the flashback in the ruin. It is known that the Number supposed to be tied to Nasch is "Number 73: Abyss Splash the Waterfall Deity".

Nasch lived life as a human at one point in time but died at some point and became a Barian. Nasch and Merag were also supposed to have been killed by Vector at some point



Earth
Also called the Human World, is a planet created along the stars and planets by first one card. It is home to millions of species of life, including humans. Due to both Astral and Barian World being high-energy worlds and unable to confront each other directly, They are also incapable of taking "Numbers" directly. Therefore, the human world has become the central battleground for the war, with many humans caught in the crossfire or direct participants.

Look below for details.

Human Recruitment
In this war, many humans have been brought into this conflict, each with their own roles to play, whether direct or indirectly.

Barian World
Due to the fact that the residents of the Barian and Astral Worlds are high-energy beings that cannot interact with each other and being unable to take the Number themselves, Barian Emperors Dumon and Vector enlisted humans to do it for them, serving as their benefactors.

Dr. Faker (withdrawn) Faker was more forced than recruited, as Vector threatened to hurt his child, Hart, unless Faker brought Vector "Numbers", which would appease him.

Hart Tenjo (withdrawn) Like his Father, Hart became a forced pawn of Vector from receiving his Barian energy, which not only gave him powers, but a few harmful side effects as well. From this he would be forced to use his powers to aid Faker in destroying the Astral World.

Vetrix Family (joined the Astral side) While Vetrix wandered the Barian world, Dumon rescued him and sent him back to Earth. Vetrix, thankful of this act, aided Dumon and was tasked to bring the "Numbers" and Dumon gave him and his sons power in the form of crests, though Vetrix only wanted one thing - revenge on Dr. Faker. After being help by Yuma, they departed for a time, but later return to help assist Yuma and friends fight off the Barians.

Trey

Fearsome Four of the Dark Dueling World

Mr. Heartland Though serving as Mayor of Heartland City and assisting Dr.Faker in the hunt for the "Numbers", Mr.Heartland had proven himself to be more willing to serve Don Thousand and Vector in their campaign for Interdimensional domination.

Mosquito Ninja

Semimaru

Kurage

Astral World
The Astral World, through the Barians' recruitment process and Dr. Faker's offering, would gain the assistance of two beings who believe in possibilities and posses incredible tenacity: the great adventurer Kazuma Tsukumo and by extension his youngest child, Yuma Tsukumo. Kazuma Tsukumo Kazuma found the Astral World for a short moment before going back to Earth with a golden relic given to him by someone looked like Astral or Astral himself, which he gave to Yuma. He and his wife began to believe that through dueling, Yuma would eventually have to bear a great and dangerous destiny. Thanks to Dr. Faker's betrayal, Kazuma was sent into Astral World again and was trapped within it. From here, he sent Astral to Earth to help Yuma.

Yuma Tsukumo Son of Kazuma and Mira Tsukumo, who dreams of becoming Duel Champion, despite being a total amateur at first. Since receiving the golden key, Yuma began to dream about a door. One day, during a duel with Shark, Yuma unlocked the Door, which led to meeting Astral, with the unintended effect of having his memories scattered into 99 "Number" cards. By teaming up with Astral, Yuma hunts down the "Numbers" through many trials and adversity, with his Duel skills improving throughout the hunt, ultimately becoming not only becoming Duel Champion of Heartland City, but also a key player in the fight against the Barians. Yuma guards the "Numbers" on his own with Trey, as Astral had to return to Astral World when he sustain major injuries from a serious last battle with Number 96: Dark Mist. However, with the help of Kite and Quinton, Yuma is currently on a journey to Astral World to find Astral. Yuma also begins to believes that there could be a way to end the war without having to destroy Barian World.

Kite Tenjo In the beginning Kite originally worked for Dr. Faker as a powerful and feared Number Hunter working to cure his younger Brother Hart from an ailment he thought could only be cured by the Numbers. Over the course he eventually met up with Yuma and nearly took his soul in their first duel, only being stopped when Kite was called back due to Hart's sickness. Kite eventually became an ally to Yuma, little by little over the course of the war with Faker and even participated in the final battle against his own Father.

Kite has become an ally against the Barians and has even developed a rivalry with Mizael who holds the only other Galaxy-Eyes monster, Number 107: Galaxy-Eyes Tachyon Dragon. Kite also holds one of the Numbers from the Numbers Ruins, Number 46: Draggluon the Ethereal Dragon.

Others
While not direct participants of either sides, there have been humans that have given their contributions in this war.

Reginald Kastle (Shark)

Shark originally started in the conflict as a Number Holder when he was possessed by Number 17: Leviathan Dragon. As time had passed through Shark went from enemy to friend and has become a steadfast ally to Yuma, even helping him in the final battle against Faker and in his battle against the Barians. Shark also holds three Number cards, Number 32 given to him by Astral and "Numbers" 73 and 94 collected from a Number ruin.

Rio Kastle

Shark's sister and also an ally and friend to Yuma. She has strange powers which she has used to help on several occasions including sensing the Barian's arrival and translating the tale of the Mad Prince from the Number Ruins. She even traveled with the group to the battlefield of Sargasso and is one of the people who can see Astral.

Super Secret Number Cards Investigation Club

The Super Secret Number Cards Investigation Club was formed by Bronk and Caswell to learn more about the Numbers after seeing Yuma use. They formed the group, although it didn't get off to a good start because almost all the members were captured by Fortuno (except Cathy) in order to trap Yuma.

The club has done a lot to assist Yuma in his "Number" hunt and also in other tasks like all of them getting Yuma his Duel Carnival medals in time and even going in the Different Dimension Airship to go to Sargasso to support Yuma and even piloted it in order to rescue "Rei Shingetsu".

Tori Meadows

Tori is perhaps one of Yuma's closest friends and has known him the longest, next to Bronk. Tori is often the one who follows Yuma into dangerous situations far more often than the other Numbers Club members. She was also the first person to be able to see Astral normally next to Yuma, Shark and Kite. She is often seen cheering Yuma on whatever he duels but isn't afraid to speak her mind to him. She was kidnapped along with the others by both Fortuno and Semimaru as bait for Yuma but it was through her encouragement that she and the other members saved themselves at Sargasso when they were about to be sucked into a black hole.

Bronk Stone

Like Tori Bronk is one of Yuma's closest friends. He is also one of the people that Yuma duels the most and used to be much better and skilled than him, however it can be assumed that Yuma is a little better now. Bronk was the first person ever to hold Utopia (without stealing it) and while he did have the usual struggle to control the Number he saved Yuma and Astral from Number 96 in their first encounter. Yuma and Bronk argue sometimes due to them being hard headed but Bronk is very often a steadfast ally to Yuma and even accompanied him to Sargasso.

Cathy Katherine

Cathy first joined the Number Club when she met Yuma after having a crush on him, even trying to get Yuma and Tori to fall out. After hearing about the Numbers Club she joined up with it. She has helped out the Numbers club in her own unique way with her cat like agility, such as when she escaped from Fortuno when the others fell and when she helped get Yuma's Duel Carnival medals to him and when she helped fight the Orbital robots. She tends to argue with the other females of the group, like Tori and Shark's sister Rio whenever they get close to Yuma.

Flip Turner

Flip first appeared as an antagonist only interested in getting Yuma's Numbers and slipped him the Baby Tiragon card to Yuma and thus use it to gain Number 39 and Number 17 in their duel. After becoming Yuma's friend Flip became a steadfast ally to Yuma. When he was caught in the Duel Carnival by Dextra and Nistro for cheating Yuma took his place and dueled in a 2 on 1 duel.

Caswell Francis

Caswell is the smart guy of the Numbers Club, along with Bronk and is probably one of the smartest in the group, even finding the source of the Crashbug Virus in the city. He had his first encounter with a Number directly when he dueled his icon Quattro in the Duel Carnival and was injured from Number 15: Gimmick Puppet Giant Grinder. Cadswell even accompanied Yuma to Sargasso.

Orbital 7

Nistro

Dextra

Anna

Triad of Terror

Number Guardian

Mach

Mach, in the past was the Pegasus steed of Dumon in his past life. When Dumon and Mach flew away on order from the King Dumon's fellow knights turned against the Kingdom and when he got back the Knights were about to kill Dumon but Mach took the attack and was killed. Eventually Mach was buried with Dumon.

Mach eventually became a Number Guardian and watched over the ruins that depicted both Dumon and his own tale. When Yuma came to claim the Number he began a duel with Mach with both Shark and his old Master Dumon's lives on the line. Eventually Yuma beat Mach and claimed the Number, with Mach's spirit inside of it.

The Number tied to him is "Number 44: Sky Pegasus" and his legend depicts Dumon

Battle Ox

Not much is known how he relates to the Legend of the Number Ruin but Battle Ox eventually came to guard the Number of the Ruin which told the tale of the Mad Prince, eventually known to be Vector. It is not known how be became the guard of the ruin of what his relation was to Vector.

Battle Ox was eventually defeated by Number 96: Dark Mist and his Number was taken from the ruin, through this Number 96 and Vector learned how to work the ruin.

The Number he was guarding was "Number 65: Judge Buster the Adjudicutter Djinn"

The Guardian of Number 54

Number 54's Guardian is not known to have any relation to Alito, to whom his legend relates to. Despite this however he seemed to recognize Alito when he took the Number from the Ruin in Spartan City.

He held the Number until Alito himself took it and was later shown his past life memories when he was defeated by Yuma.

The Number he guarded is "Number 54: Lion Heart"

Jinlong

Jinlong was a Dragon in ancient times who was the friend and servant of a Dragon Tamer named Mizael. They protected the land until a wondering Shaman from the opposing land came through and accused Jinlong of causing disasters. The villagers were about to put him to death until Mizael interfered but in their moment of weakness Mizael and Jinlong were put to death and their lands overrun.

Jinlong took on the form of an old man and became the Guardian of a Number, when Yuma and the gang found the Ruin he challenged Kite to a duel with Kite emerging the victor. Kite then took the Number. Mizael then appeared shocking Jinlong as Mizael couldn't remember him. Eventually the power of the two Neo Galaxy-Eyes monsters caused the ruins to erupt however Yuma and the gang were saved by Jinlong who told them to not let the past repeat itself.

The Number tied to him is "Number 46: Draggluon the Ethereal Dragon"

Ponta

Ponta was the pet Tanuki and friend of Kiraku Souhachi, the past life of Girag. Ponta acted as a body double for Girag and the two of them won many battles, but eventually Girag knew they would lose and sent Ponta away to save his life. He held a powerful grudge against Girag for many years while he was stuck in stone.

He was unleashed when the statue was found the took Girag's body for himself and challenged Yuma to a duel, switching bodies with Yuma as well. Eventually Yuma won the duel when Girag had remembered about his past life, although when Ponta gave up his body he attacked the Number Spirit and devoured him, although not before he had given Yuma the Number. Ponta was shown to be alive inside of Girag.

The Number tied to him is Number 64: Sandayu the Vetanuki.

Abyss

Abyss is the spirit of a water god that was summoned by Vector to attack the Oceanic Land which was ruled over by King Reginald and his sister Rio. Abyss was summoned through a blood sacrifice and did enormous damage to the land. When Rio realized what Vector had done to summon him she rode on horseback to the rescue in order to sacrifice herself to purify the water god. She summoned Crystal Zero the Ice Princess to stop Abyss. What happened after is unknown.

In the present he used his power to possess the present day version of Rio to duel Shark in the present. Throughout the duel Abyss showed Shark visions of his past life which were seen by Astral and Dumon also. Reginald defeated Abyss who informed him of the fact that he only did all of this on orders from his past life. Reginald kept the two Numbers from the ruin.

It is not known which of the Barian Emperors these two Numbers refer to though from comments by several characters "Number 73: Abyss Splash the Roaring Waterfall Deity" is the Number of Nasch and "Number 94: Crystal Zero the Polar Ice Princess" refers to Merag.

Current Events
Before WDC

During a duel with Shark to get Bronk's deck back, Yuma opened The Door in a vision. From this door, Astral appeared and tried to merged with him, but somehow his memory was lost and scattered into 100 "Number" cards. Despite the memory loss, with Astral's advice and receiving "Number 39: Utopia", Yuma was able to make a comeback and win the duel, retrieving Number 17: Leviathan Dragon from Shark.

At first, Yuma reluctantly began to work with Astral to hunt down "Numbers" in order to help regain his memory, making a name for himself due to defeating Shark and a few new friends along the way, like Flip Turner, Caswell Francis, Nelson Andrews, Cathy Katherine and even Shark himself after helping him out of a jam. However, this most unlikely duo would soon discover that they weren't the only ones hunting for "Numbers".

They soon crossed paths with a young, yet powerful rival "Number" hunter named Kite Tenjo. During their first duel face-off, Kite had proven himself a formidable and terrifying opponent, as he easily overpowered Yuma and Astral, despite their best efforts, especially after he brought out his ace monster Galaxy-Eyes Photon Dragon. Just as Kite was about make his crushing finishing move, his brother Hart began to collapsed, forcing him to cancel the duel to go to his aid, but gave Yuma his name and told him to remember it before leaving. This horrifying nearly devastating loss and by extension near-death experience left both Yuma and Astral's spirits crushed. However, during the next few days, this experience would ultimately help them grow stronger as duelists and partners.

At grandmother's request, Yuma and Astral trained with Roku at the Duel Sanctuary. Despite being his students for only a couple of days, the results the training proven to be magnificent, as when they faced off against an old student of Roku's, Kaze, who had fallen under the influence of Number 12: Crimson Shadow Armor Ninja, Yuma managed to win thanks to Roku's teachings about how Duel Monsters are alive, claiming the "Number" and helped reformed Kaze. Before leaving, Roku gave a newly rejuvenated Yuma the Legendary Deck Kaze was after, giving him the means to put together a new, stronger deck capable of taking on the challenges that await at the WDC.

While the trip to the Duel Sanctuary had restored Yuma's spirit, Astral still had doubts in himself from the duel with Kite. Meanwhile Tori,Bronk,Caswell, Trip and Cathy began to grow concerned as numerous incidents kept occurring that revolves around the "Number" cards and how Yuma is becoming more and more involved with the "Numbers", they decided to form the Super Secret Number Cards Investigation Club to learn more about them for Yuma's sake. Unfortunately, their search gets them caught by a fortuneteller named Fortuno who claims to be a servant of Kite except for Cathy, who manages to get away. When she finds Yuma, Fortuno possess her in order to introduce himself as a servant of Kite and tell him to come if he wants to save his friends. While Astral was against it due to his lingering fear of Kite, Yuma was not afraid to face Fortuno to save his friends.

When they arrived, before dueling it out for the "Numbers" Fortuno claimed himself a servant of Kite and said that Kite himself would be watching the dueling, scaring Astral, but Yuma managed to keep his spirit burning. During the duel, with his friends' lives on the line, when Astral found Yuma overwhelmed, Fortuno offered a deal that he would spare Yuma's friends in exchange for the "Numbers". At first, Astral was willing to be sacrificed, Yuma refused and after figuring out the "Kite" that was watching was in fact just a statue, Yuma told Astral that he was his friend. With both their spirits ignited, Astral gained a new power in the form of Chaos Number 39: Utopia Ray in order to win the duel, claim both Number 16: Shock Master and Number 11: Big Eye and save their friends, who saw Astral for a brief moment when he gain a new power, thereby confirming his existence, afterwards the real Kite came and took Fortuno's last "Number"along with his soul.



Astral eventually learns about Yuma's parents, even how he got the key from another world. Along with gaining a new friend, Yuma and Astral would come face to face with a fierce new enemy in the form of a Forbidden "Number" card, Number 96: Dark Mist. With Bronk Stone's help Astral managed to seal Number 96, but it is clear that they have not seen the last of him.

Yuma is surprised from being told of a ship within his key by Astral. Astral also states that only by gathering the "Numbers" will they be able to solve its mysteries. Meanwhile, Kite began to grow more concerned for Hart as his physical and mental well-being continued to worsened from using his powers, but Hart insisted on continuing since he believed he was helping the world, while Mr. Heartland told Kite to focus on gathering "Numbers" if Hart is to be healed. Kite suspected that Dr. Faker was hiding the truth behind the mystery of the "Numbers", so he had Orbital 7 research their origins, which lead to Kite seeking the Emperor's Key Yuma wears which their connected to.



When putting the key away partially at Caswell's behest, Yuma considered that he should be more careful with it after learning about a ship within. After leaving to head to class, Orbital 7 came in and tried to steal the key, but Shark intervened and tried to keep the key away. When cornered on the roof and was about to been attacked, Kite stopped Orbital. After demanding the Key from Shark, he refused and after learning Kite is the "Number" hunter that he's been hearing about and lied about being a "Number" holder himself, a duel ensued. Despite Shark being an expert duelist himself and having a new Anti-"Numbers" deck that was effective against Yuma, Kite once again proven to be far superior in terms of dueling skills. He even allowed Shark to steal his Number 30: Acid Golem of Destruction, the latter being unaware of it's negative effects. Despite Shark resolving to not give up like Yuma, Number 30 still proven to be his ultimate downfall in the duel, resulting in an easy win for Kite. When stealing Shark's Soul, he absorbed it after seeing that it didn't have a "Number". Since facing Yuma again wasn't an option due to already using 85% of his Photon Transformation's power, he simply took the Key and flew off. Meanwhile, in the Key, Astral has been trapped inside when it was deactivated, and the set "Numbers" became cards again. The cards then surrounded Astral and a voice told him that he needed to obtain the "power of ZEXAL". With the help of Mr. Kay, Yuma, along with Tori, Bronk, Caswell, and Cathy manage to track down Kite at an old warehouse. Meanwhile after analyzing the Emperor's Key,with Orbital mentioning that nothing from Earth would react to it, Kite suggest using a Baria Crystal, which worked. After opening a portal, Kite then jumps in to find himself in the Key's inner Pocket Dimension. It is here that Astral and Kite meet for the first time, though from asking Kite why he was here, Astral revealed that he already knew of Kite. When Kite ask how Astral knew his name, the latter revealed that he fought him once alongside Yuma, which is proven true when Kite sees Number 39: Utopia, one of the "Numbers" Yuma used the last time they fought. When Astral ask why Kite he hunts "Numbers", Kite ask Astral the same. Astral explains that the "Numbers" are his memories, which intrigues Kite. Kite, while not explaining his real reason for hunting "Numbers", then explains that he wants to know their secrets, along with those of Astral World and Barian World, with Astral wondering about Barian World. Kite states that the best way for him to the answers he seek is to collect all the "Numbers", which lead to him demanding Astral to hand over the ones he posses. Astral refuses, since the "Numbers" are his only chance of regaining his memories, which leads to Kite challenging him to a duel, with all their "Numbers" on the line.

At first, thanks to Astral playing defense out of fear of Kite summoning Galaxy-Eyes Photon Dragon, Kite managed to ploy through his defensive strategies and gain a huge lead in the duel. After realizing that he's has no need to be afraid, Astral managed to summons out Chaos Number 39: Utopia Ray and even out the plain field for a moment. However, after summoning Galaxy-Eyes Photon Dragon, Kite once again began to overwhelm Astral to the point of having only 400 life points left. At this point Astral was ready to give up.

Meanwhile, with the help of his friends, Yuma was able to get past Orbital 7 and his security forces and find the key, while learning about someone close to Kite. Yuma then finds himself in front of The Door again. It then opens again and tells Yuma to use ZEXAL, but repeats Yuma's previous warning about losing something precious to him. Astral was able to sense Yuma's presence and informed him about the Duel, as well as telling him he's already about to lose. After Astral tells Yuma about ZEXAL, Yuma convinces Astral to not give up, and crosses the door, landing in the dimension inside the Key. Astral and Yuma receive the ZEXAL (power), fusing themselves in the process. Using this new power, Astral and Yuma created a card that allowed "Utopia Ray" to defeat "Galaxy-Eyes". Kite, in a pinch for the first time, managed to end the Duel in a draw. Before escaping, Kite told Yuma that he is hunting "Numbers" to save his brother and then gave Shark his soul back.

The next day, while talking about the events that took place last night, an wave of energy from the Astral World and another world passed through Earth causing time to temporally stop and allow Kite to invade his memories. Yuma looks up at the sky, seeing a blue, red, and a yellow sun with one of them belong to Astral World. At their tower, Mr. Heartland asks Dr. Faker what just happened. Faker replies that a wave has hit the Earth, originating from the Astral World and another world. Time has temporarily stopped because of it. He tells Heartland not to panic - time will be restored as if nothing happened once the wave passes. However, he also remarks that this means that there is no doubt that the other two worlds are getting closer. The final stage will soon be set as they must deal with Astral World. When Yuma and Astral met up with Kite after the space-time phenomenon passes, he tell them that they will settle things at the World Duel Carnival.

World Duel Carnival
In an effort to help Kite Tenjo gather "Numbers" more quickly, Dr. Faker and Mr. Heartland devised a very clever plan: Holding a Duel Tournament called the World Duel Carnival. Duelists from all over the World will come to Heartland City to wage heated duels, all to claim the Title "Duel Champion". Thanks to Kite, Yuma was allowed to be in the tournament when he failed to sign up in time, though this was initially so that Kite would have another chance to face Astral. Shark also entered to get revenge against a Duelist who wrong him and his sister in the past, gaining a heart piece from the duelist. During the tournament, Yuma and Astral faced off against not only Kite and Shark but other strong duelists as well, Number holders or otherwise, including those of a more mysterious, powerful and sinister group known as the Vetrix Family.

WDC Preliminaries
After only a full interesting first day of the Carnival, Yuma managed to obtain three of the five fitting Heart Pieces needed to advanced to the WDC Finals, along with one "Number" by night's end.

Day Two

While day one of the Carnival was relatively easy and somewhat calm, things began to take a more serious and tumultuous turn as day two unfolded, starting with Yuma witnessing the ruthless dueling of Quattro as he delivered a brutal defeat to Bronk and Caswell, followed by watching Shark duel for vengeance against Quattro but was forced to take on and defeat his younger brother Trey, who give him "Number 32: Shark Drake" for his victory. Watching what has happened got Yuma so angry that he unintentionally snapped at Tori who was trying to cheer him up, causing her to walk away angry and hurt, leaving Yuma alone to cool off. Unfortunately, she walk right into a dangerous situation caused by Cameron Clix, who is under the influence of "Number 25: Force Focus, forcing Yuma to face him in order to prevent a major disaster. In the end, Yuma was able to overcome the future sight ability the "Number" gave, and beat Cameron. Kite stopped the blimp Tori was on from crashing, only doing so to prevent the World Duel Carnival from being cancelled from the event causing mass panic within the city. Afterwards, Yuma gained his fourth fitting Heart Piece, the Number and an apology from Cameron for his actions while under possession.

Later, Yuma had to duel both Dextra and Nistro to save Flip from a cruel punishment for being caught using "tricky ideas" to collect Heart Pieces. Yuma had to duel on his own for most of the Duel without his "Numbers" or Astral, as Astral had problems of his own in the Emperor's Key once again dealing with Number 96: Dark Mist. Dealing with the duo's teamwork was no easy feat since it had him cornered for most of the duel and in an attempt to counter attack, Yuma was finally able to summon Number 39: Utopia, surprising them with the fact that not only did he held "Numbers" cards, but also that Yuma revealed that he once tied with Kite after he noticed that they were using Photon cards like Kite, becoming aware that they were working as his colleagues. Yuma nearly gave up as his counter attack attempt failed, but then Astral returned after managing to suppress Number 96 once again, briefly revealing himself to everyone watching the Duel - revealing to Nistro and Dextra that Yuma is cooperating with the Original Number. With Astral's help, Yuma made a winning comeback and won the duel. Afterwards, the duo decided to stay quiet about Yuma since Nistro wanted the chance to defeat him before Kite does.

Later at night, things became more dangerous and dark, beginning with Yuma's encounter with a boy named Hart. Hart snuck out to find Kite, when he was found by Yuma, Astral and Tori, who then bare witness to his incredible powers, which included being able to see Astral. At Astral's request, Yuma brought Hart back to his home to learn more about him. Yuma and Hart became friends over dinner, but then Hart wandered out into the night again, with Yuma going after him. When Hart began to panic again, Astral told Yuma to give Hart some caramel to calm him down. After learning that Hart was looking for Kite, Yuma remembered him as Kite's brother and then promised Hart the he would help him find Kite. Quinton then arrived and brainwashes Hart into coming with him, fooling Yuma that he knows Kite. While leaving with Quinton, Hart mentions that his mission was to destroy Astral World, shocking everyone. After meeting up with Kite and realizing that someone who wasn't working with him took Hart, Yuma joined forces with Kite to save Hart on the promise to bring the two brothers back together again.

When they manage to locate Hart in a old gallery, they were forced into a Tag-Team Duel against members of the Vetrix Family, Trey and Quattro as they were being stalled while Vetrix completes the ritual to gains Hart's powers. At first, Trey and Quattro saw Kite as the only threat, but as the duel progressed, they were forced to be wary of Yuma as well when he not only revealed himself as a "Number" hunter from summoning his ace monster, Number 39: Utopia, but also when he continued to defend Kite from their combination attacks at the cost of his life points (something that impressed Trey, especially), and defeat Quattro's ace Number 15: Gimmick Puppet Giant Grinder by bringing out his Chaos Number 39: Utopia Ray, something that not only shock them as they were unaware of the existence of Chaos Numbers, but also made Quinton, who was observing the duel, realized that he was the son of someone he remembered. Ultimately, Kite managed to win the duel when he used the last of the power Hart sent to him to summon Neo Galaxy-Eyes Photon Dragon, but neither he nor Astral were able to take the duo's "Numbers" due to the power of their Crests, with Trey seeing Astral in the process. Quinton then gave a comatose Hart back to Kite and tells Yuma about his father being alive and in Astral World. While he was getting ready to head out to find Kazuma, Roku manage to convince him that convince not to seemingly run away from his problems and told him that through dueling and the bond with his father he will one day find him. With this and the new info about Mr.Heartland, Dr.Faker and Kazuma are somehow connected, Yuma was more determined than ever to win the WDC. Meanwhile after Vetrix gains mastery over his new powers, he learned from Quinton that Yuma Tsukumo possesses the "Original Number". However, because of Yuma's surname, Vetrix wonders if he is the son of Kazuma Tsukumo, which Quinton answers as correct, surprising him and making Yuma a prime target as well.

Day Three

During the third and final day of the WDC prelims, Yuma struggled to find a duelist to beat for his last fitting Heart Piece for most day, but meet up with some old faces like Nelson including some more recent encounters. Due to the events of the previous day, Yuma and Astral gain the attention of some seriously strong duelists, like Nistro and Dextra, who resigned from the WDC staff and joined the tournament on Nistro's desire to have a rematch with Yuma, along the Vetrix Family, most particularly Trey after seeing how Yuma dueled was how Kite was able to win, and Vetrix himself due to his relation to Yuma's Father and learning of his relation to the "Original Number".

During his search for his final opponent, Yuma learned of Shark's brutal dueling after seeing the hurt duelists he's beaten. In an effort to help Shark let go of his need to duel for vengeance, Yuma challenged him to a duel. In reality, Yuma only planned to let Shark take his anger out on him and doesn't even fight back. Once Shark realize this, Yuma's plan succeed and manage to make "Number 32: Shark Drake's" darkness over Shark disappeared. Before he walked off, he told Yuma that they would meet in the finals and gave him a smile.

After watching the duel from afar and hearing Yuma mention his father, Trey sneaks into Yuma's house and looks around his artifact-filled attic. After Yuma comes back and meets up with Trey, while talking about how Yuma duels, they began to bond. But during lunch, after seeing how much Yuma's family is like what Trey's used to be, Trey cries and leaves.Trey then decides, for his family, to challenge Yuma to a Duel in order to acquire Yuma's power of never giving up until the very end. Vetrix agreed to this and told Trey he would give him new powers to help him beat Yuma. Vetrix then performed a ritual on Trey, similar to the one he had with Hart, transferring some of his power into Trey's crest, which Vetrix called the powers equivalent to the pain that Trey had felt in his life. In addition, he gave him two new cards - "Number 6: Chronomaly Atlandis" and "Final Prophecy". Vetrix told him that the former card would put him a great strain on him both physically and mentally and that the latter card would ensure that both players do not walk away unharmed. That evening, Trey awaited Yuma's arrival atop a series of unfinished roads. Yuma told him he believed they could become friends after the Duel, and Trey told him he must defeat Yuma to save his family. The two then began to Duel, with Trey telling Yuma that with his new powers, he can't be defeated, and was also able to clearly perceive Astral. During the Duel, Yuma tried to reason with Trey and shocked by his sudden change in personality. Trey then uses his new powers to erase Yuma's memories of "Kattobing" and his father's teachings. Due to the power of Trey's Crest, Yuma is unable to see Astral or the Emperor's Key. Without his "Kattobing", Yuma also becomes weak and cowardly, and wants to surrender the Duel. Trey refused to let Yuma quit the Duel and brutally attacked him, causing Yuma to nearly fell off the highway until his friends saved him. With some help from his father inside the Emperor's Key and Astral using the his bit of power, Yuma was released from Trey's influence and regained ability to see the key and Astral. Upon returning to normal, Yuma learned that Trey destroyed Astral, which makes him mad and cried for his friend. Remembering the lessons Astral gave him, Yuma proceeds to use "Number 39: Utopia" and later "Number C39: Utopia Ray", but Trey counters with Number 6:Chronomaly Atlandis. Trey uses the Trap card "Final Prophecy" to protect "Atlantis", but doesn't realize that the card opens a portal to the unlocked the door to the Barian World, which threatened to destroy all of existence. Trey's Crest starts damaging his body, but Yuma manages to convince Trey to work together with him to revive Astral. Using the ZEXAL power, Yuma and Astral performed a Shining Draw - "ZW - Phoenix Bow", and equipping it to "Utopia Ray", Yuma defeated Trey. and "Atlantis". After Yuma's victory over Trey, Trey gives Yuma his "Numbers" and a Heart Piece and leaves asking Yuma to save his family.

WDC Finals
Thanks to his victory over Trey, Yuma is allowed to advanced to the WDC finals. However, at the finalist party, Yuma and Astral see Vetrix for the first time, who declared vengeance against the pair for putting Trey in a coma after defeating him. To this end, and losing faith in his remaining sons, set forward two separate plans: Hiring the Triad of Terror to attempt beating Yuma and Shark. Battle of the Duel Coaster

Due to forgetting his Heart Piece, Yuma got a late start, with Tori riding along, and unfortunately to make matters worse, this made it easier for the Triad of Terror to launch their 3 vs.1 duel ambush against him. However, thanks to Anna, and her sacrifice as well as Nistro's interference, Yuma was able to defeat the Triad of Terror but only has 600 Life Points left.



As the semifinals goes into the underground section of the Duel Coaster, the field narrows to eight Duelists, who speed towards four special Duel Fields. In the process, Kite and Dextra attempt to become Vetrix's opponent, while Nistro chases after Quinton and Yuma blunders into Trap Points costing him life points. After getting lucky enough to retrieve 2000 life points on a all or noting trap point, Yuma goes to save Nistro from Quintion's finishing move, while delivering him some damage in the process. Vetrix stopped Quintion's furious retaliation, and told him to leave Yuma alone for now. Meanwhile, Dextra managed to become Vetrix's opponent before Kite and forced Vetrix into a jungle field to begin their duel.Before Dextra's Duel with Vetrix could begin, Mr. Heartland cut the footage so that they could Duel at their best. Vetrix asked why she was doing so much for Kite, and she responded that she loved him and expressed a desire to fight without relying on others, just as Kite had. On her first turn, Dextra set up a masterful strategy comprised of "Photon Papilloperative", "Butterfly Charm", "Elimigate", and "Butterfly Swarm", which in combination with the "Jungle Field" restricted Vetrix's actions within the Duel. Despite this combination in conjunction with her large amount Life Points she gained before battling him, Vetrix managed to Xyz Summon his "Number 8: Heraldic King Genom-Heritage" and defeat Dextra. This resulted in her not only being eliminated from the World Duel Carnival, but also having all of her memories of Kite wiped clean from her mind. While Dextra was left psychologically scarred in Yuma's arms, she requested of Yuma to make sure that Kite did not forget her. After seeing this, Yuma vows to defeat Vetrix.



Quinton and Kite arrived at the Space Duel Field, "Space Field", where Quinton remembered the day he become filled with hate. They began their Duel, with Quinton bringing out "Number 9: Dyson Sphere" on his first turn, which sealed Kite's attacks. When Yuma arrived, Quinton explained that Vetrix is his father and revealed his past history with both Dr. Faker, who is Kite's father and Yuma's father, Kazuma Tsukumo. Quinton was able to reduce Kite to a mere 100 Life Points with "Dyson Sphere". He questioned why Yuma considered Kite to be a friend and was reminded of Kazuma by Yuma's answer. Quinton still questioned how Yuma could have the son of the person responsible for his father's absence as a friend. Quinton told Kite his family had thrown away their own names for revenge.He wished to save his father, but his heart was already filled with revenge when he returned. Kite told him that was wrong - he fights to oppose his own parent, Faker. Quinton was surprised at how strong Kite had become, and Kite told him he would inherit Quinton's feelings and settle things with Vetrix for him. Bringing out "Neo Galaxy-Eyes Photon Dragon" with the aide of a card Faker had give him, "Message in a Bottle", Kite defeated Quinton. Quinton left through a portal, leaving "Dyson Sphere" behind for Kite and put his faith into him.



Meanwhile, Quattro used Shark's anger against him by leading him toward the Magma Field. Since Shark's Deck was composed of WATER monsters, he would be at a disadvantage. Shark was prepared to counter the field, "Magma Field", using cards such as "Plate Salvage" and "Adapt to Adversity". He brought out "Submersible Carrier Aero Shark" on his first turn, inflicting 1200 damage to Quattro before he takes his first turn. Quattro countered with "Number 15: Gimmick Puppet Giant Grinder", which Shark countered with "Number 32: Shark Drake". Vetrix appeared, revealing that he intended to use Shark as an assassin to defeat Dr. Faker. Shark insisted that won't happen, with Vetrix responding that he'll have no choice - he will become Vetrix's puppet. After Quattro managed to Summon "Number 40: Gimmick Puppet of Strings" and using the effect of "String of Destiny", Quattro attacked Shark a total of eight times. Quattro revealed that he had been manipulated by Vetrix and that Shark's sister was hospitalized as a result of a fire caused by "Flaming Hell Blessing". Shark told him not to act like he was the victim, even if he was used by Vetrix, Quattro was still responsible. Quattro Summoned "Number 88: Gimmick Puppet of Leo", which would let him declare an Automatic Win on his next turn. Vetrix advised Shark to accept "Shark Drake" in order to win and have his revenge. After some resistance, Shark gave in to and was able to create "Number C32: Shark Drake Veiss" as a result. He defeated Quattro, with Vetrix musing that now he and Shark are friends, mocking Yuma's spirit of "kattobingu". Quattro apologized for hurting his sister and urged Shark to defeat his father and save him. Quattro also added that if Shark wanted to hate someone, he should hate Quattro, not Vetrix. Shark watched as Quattro departed through a portal and talked with Yuma. Now wanting revenge against Vetrix as well, Shark told Yuma he would not forgive him if he got in the way. He boarded his Duel Coaster and moved on, having advanced to the semi-finals.

After Yuma had witnessed all of the other semi-final Duels, he ended up arriving at the "Desert Field" field to see that Nistro was waiting for him. By then, Nistro had recovered his Life Points back to 4000. With Yuma only having only 100 Life Points himself, Nistro decided to restore him back to 4000 via the effect of "Heroic Gift" as he wanted to have a fair and fiery Duel with Yuma. Despite this, Yuma continued to play defensively, which annoyed Nistro as he expected an enjoyable Duel. Yuma then realized this and began to Duel up to Nistro's expectations. Midway through the Duel, the field switched to "Sunset Showdown". Wishing for the Duel to be decided by a battle using their respective ace monsters, Nistro played "Xyz Xtreme !!", letting him and Yuma Summon "Excalibur" and "Number 39: Utopia", respectively. Yuma increased the ATK of "Utopia" with "Double or Nothing!", winning him the Duel. Despite his loss, Nistro wished Yuma luck, and gave him "Excalibur".

During the one night break before the the semi-finals the next day, Yuma tries to retrieve his deck, which he somehow lost in Heartland. After a while he managed to find it, but not before getting a look at Hart in a coma and meeting Dr. Faker for the first time.

Battle of Heartland Duel Tower

Bond of Rivals/Friends vs. Powers of Revenge Yuma was matched up against Shark on the Duel Tower during the semi-finals. During the first phase, Shark made no real attempt and Yuma was easily able to to reduce his life points. Only after Shark made his devastating counterattack and took a huge chuck of Yuma's life points, did he realize that Vetrix is influencing Shark.

While trying to bring Shark to his senses, Yuma held out until he finally managed to summon "Number 39: Utopia", which he needed to fulfill his plan. He attacked with "Utopia", negated his own attack and activated "Rivals Unite", which gave him control of Shark's "Number C32: Shark Drake Veiss", allowing Shark to recover from Vetrix's influence, but forcing himself to suffer the darkness. Yuma had a way to get rid of "Shark Drake Veiss" by releasing "Rivals Unite", but that would make the "Number" possess Shark again. However, Yuma knew if he did not, he'd have to take the effect of "Heraldry Catastrophe", which could defeat "Utopia" and make Astral disappear. Shark, who could not stand watching Yuma in pain, activated "Underwater Snow Prison", banishing "Shark Drake Veiss" and causing himself to take 1000 damage, giving Yuma the win. After the Duel, Shark reminded Yuma that he was a good friend and thanks Yuma for saving him. As Shark was flown off to the hospital, Yuma vowed to inherit Shark's will and win against Vetrix, while an outraged Vetrix, causing him to smash the observation boxes windows out of anger and he vows to finish Yuma off, nice and slowly.

Master Avenger vs. Galaxy-Eyes Master During the semifinals, Kite speaks to a comatose Hart and tells him he's leaving for the semifinals now and promises to defeat the remaining two Duelists to save Hart, even though his "Photon Transformation" is already damaging his body. Before proceeding to Duel Vetrix at the Duel Tower in the semifinals, Kite was greeted in the hallway by Yuma, and told him and Astral that he would meet them in the finals. The Duel began and Vetrix revealed an AR mask identical to Hart's face. Due to the connection forged between Vetrix and Hart during the ritual, Vetrix could inflict pain on Hart by hurting himself. Kite attempted to leave to help Hart, but Vetrix snared him with a Duel Anchor. Yuma and Orbital 7 departed for Heartland Tower in Kite's place. Continuing the Duel, Kite matched Vetrix's "Number 8: Heraldic King Genom-Heritage" with his own "Galaxy-Eyes Photon Dragon".

Vetrix accused him of enjoying his actions as a Numbers Hunter, which Kite fiercely denied and justified it was only to cure Hart. Yuma and Orbital reached Hart, and Yuma and Astral entered Hart's consciousness. There, Vetrix appeared to them in the form of the dragon, which Yuma slew with "Number 39: Utopia", severed the connection between Vetrix and Hart. Kite continued an aggressive strategy, bringing out "Neo Galaxy-Eyes". Though he nearly defeated Vetrix, the latter brought out "Number 69: Heraldry Crest" which required immense rage to control it. Vetrix says he has no emotion, thus he cannot produce rage. That is why he endeavored to make everyone angry. He says he used everyone - Dextra, Shark, even his own sons. Kite is confused and Vetrix says he did quite well too, he contributed much rage due to Hart's situation. He adds that thanks to that, he was finally able to Summon this card. This "Number" then absorbed the effects of "Neo Galaxy-Eyes" and defeated Kite. He was saved from further physical harm by Hart, who projected a shield to defend him. Vetrix used his crest to take Kite's "Numbers", as well as his soul, leaving Kite in a comatose state.

War of the Numbers: Avenger of Barian vs. Users of Zexal'' Having had advanced to the final match, Yuma goes against Vetrix in the Sphere Field, which would allow Dr. Faker to gather the energy of the "Numbers" Vetrix and Yuma would wield, as its effect allowed "Numbers" to be easily Summoned. Yuma confronted Vetrix about his sons' fates, and he revealed the price they paid by wielding crests, while telling Yuma how it was his father whose words inspired him to survive. Yuma told Vetrix of his promise to Trey to save his family, and would fight for Vetrix's sake as well. When Vetrix queried Yuma did not want revenge on Faker, Yuma insisted his father would not want that, but Vetrix suggested that perhaps his father's own plans of revenge had already begun - the manifestation of Astral in this world. The Duel began, and using the "Sphere Field" effect, Yuma summon "Number 12: Crimson Shadow Armor Ninja" to destory Vetrix's "Number 56: Gold Rat". Vetrix responded by bringing out three "Numbers" in a single turn - "Number 10: Illumiknight", "Number 30: Acid Golem of Destruction" and "Genome Heriter". Yuma survived via the effect of "Armor Ninja" and "Half Guard" and was able to match Vetrix's move by Summoning "Number 17: Leviathan Dragon", "Number 34: Terror-Byte" and "Utopia".

Using his "Numbers", Yuma managed to destroy all of Vetrix's "Numbers", putting him at a disadvantage. However, Vetrix made a comeback by Summoning "Heraldry Crest", which absorbed the effects of all of Yuma's "Numbers" and reduced him to 500 Life Points, but after he casts the mask from his face and shows his true face for all to see: the right side of Vetrix's face appears as a glowing image of space, with a black hole for an eye. The left side of his face appears normal, though marks similar to those on the face of "Heraldry Crest" appear in the middle of it and reveals that as he wandered the fissure of the different dimension, his face was transformed into what he sees now, claiming all he has left in his body is his heart of revenge. After recovering from the attack, Yuma chose not to give up and renews his desire to deliver what Vetrix's sons entrusted him with to Vetrix. Despite the many spectators watching, Yuma tells Astral that their only chance of beating Vetrix is to use ZEXAL. After agreeing, they both perform Xyz Change ZEXAL, surprising everyone watching, including Faker and the crowd starts to cheer Yuma on. After Vetrix expressed being surprised that they hid that secret technique of fusion the whole time, the duel continued and Yuma and Astral then performed a Chaos Xyz Evolution and Summoned "Number C39: Utopia Ray", equipping it with "ZW - Lightning Blade". When they attacked with "Utopia Ray, the "Heraldry Crest"'s effect negated the attack, but Yuma survived with the effect of "Lightning Blade". Yuma narrowly survived Vetrix's next attack by using "Half Unbreak", and proceeded to use the power of ZEXAL again to perform the "Final Shining Draw" and equip "Utopia Ray" with "ZW - Tornado Bringer". Vetrix evaded this move with "Heraldry Burst", but Yuma was able to overlay his two "ZW -" monsters to Xyz Summon "ZW - Leo Arms". Using its effect, Yuma was able negated the effects of "Heraldry Crest" and boosted the ATK of "Utopia Ray" enough to defeat Vetrix and was named the "Duel Champion" of the WDC.

Faker absorbed the "Numbers" of both players with the Sphere Field and nearly absorbed the Duelists themselves.Yuma wielded "Lightning Blade" with his own hands and saved Vetrix, similar to when his father tried to save Vetrix once before. Vetrix was confused as to why Yuma rescued him, Yuma insisted that everybody can change, and that his family needed him. After Vetrix releases the souls he capture, he let go of Yuma's hand and thank Yuma for he done as he fell into the core, much to Yuma's horror. Yuma is then captured into the Sphere Field and transported to Heartland Tower in front of Faker.

Battle against Vector,the Barian manipulator

Vs. Faker

Yuma meets up with Kite and Shark while attempting to rescue Astral from Faker and the Sphere Field. Astral sends him out of the Sphere Field in order to save his life but also gives him "Number 39: Utopia" and "Number 32: Shark Drake". He gives Shark Drake to Shark and the three of them began their duel with Faker.

With Faker taking the first turn he quickly summons his own Number, "Number 53: Heart eartH". Using this monster he is able to take the attacks of Yuma, Kite and Shark using the devastating abilities of "Heart Earth" as well as his Garbage Monsters. Yuma attacks head on, while Shark tries a more strategic approach however Kite ultimately destroys Heart eartH with Galaxy-Eyes. However when "Heart eartH is destroyed a new Number takes the place of the destroyed one "Number 92: Heart eartH Dragon".

The new Number is few stronger than the other one and has numerous special abilities. Yuma, Shark and Kite have to use every trick they know of in order to survive such as Shark's "Escape Lure" and Kite's "Kuriphoton". Dr. Faker is even skilled enough to escape the power of the Chaos Numbers as Yuma and Shark summon "Number C39: Utopia Ray" and "Number C32: Shark Drake Veiss" and both monsters are banished by Heart eartH Dragon, however thanks to some tactics from Shark Kite is able to summon Neo Galaxy-Eyes Photon Dragon and destroy Heart eartH Dragon by negating it's effects.

After the Number is destroyed Faker suddenly proclaims that Kite is not helping Hart but doing him harm. He then explains the deal he made with the being of the Barian World, later revealed to be Vector. Kite and Faker make amends but the duel is not over yet when the Barian reveals itself and takes over Faker's body.

Vs. Vector

With Vector continuing the duel in Faker's place reviving the fallen Number and using it's effect to power it up by the amount of banished monsters. The Barian is even able to use Barian cards to power up the deck and push the trio further and further toward defeat.

Kite and Shark are injured after a brave attempt to destroy the Barian. Hart is able to free Astral from the sphere field using the Barian's own power against it and in doing so Astral and Yuma morph into Zexal and using Shining Draw bring out ZW - Ultimate Shield and summon their banished ace monsters. Yuma then uses the power of Xyz unity combined with their three monsters to destroy the Barian (at least they thought they had, though Vector survived). After this the tower began to collapse with Faker falling down the tower and Kite going down to rescue him.

Yuma in Zexal follow the two down the tower while Orbital 7 takes Tori, Hart and Shark away from the tower. Yuma saves Kite and Faker from falling down the tower although only have a tenuous grip. Vetrix appears and appears to send the three (four if Astral is included) to their deaths. However instead saves them by using the power of his crest, which had changed color. All three of them appear outside the tower safe and sound. Faker even having talked and apologized to Vetrix. Yuma asks a match with Kite as his prize for winning the Duel Carnival.

Yuma vs. Kite: Round 3

Due to his wish as the winner of the Duel Carnival Yuma wishes a duel with Kite. Although Yuma is excited about the match and the chance to duel the former Number Hunter Kite isn't as focused as he usually was due to the confusion about his reasons for dueling, as he did not have to duel to help Hart anymore.

Kite plays most of the match with no passion and doesn't use any of his usual brutal and to the point tactics, even after summoning Galaxy-Eyes. Eventually Kite regains his dueling spirit after some heart felt words from Astral and some of Yuma's antics.

As the duel continues Yuma and Kite continue to one up each other through their respective Xyz monsters and tactics. Yuma eventually summons Utopia Ray to battle with Kite, who responds by summoning Neo Galaxy-Eyes. Both duelists end the duel by using the exact same card "Xyz Double Back" to summon back their respective ace monsters Utopia and Utopia Ray for Yuma and "Galaxy-Eyes" and "Neo Galaxy-Eyes". Kite eventually wins the duel after a hard fought match.

Even though he loss, Yuma was okay with it, but vows to one day beat Kite, with Kite saying he looks forward to dueling Yuma as many times as he like, finding a new purpose in dueling, before leaving with Orbital 7. Yuma then feel asleep on Tori, with Astral making his twenty-first observation: "It appears one can feel good about a loss as well". But Unknown to both Yuma and Astral, despite the set-back, the leaders of Barian World are making next plan to defeat the Zexal pair. The war of the worlds has only just begun.

Attack of the Barians
Due to Vector's failures with his pawns and his presumed death, the Seven Barian Emperors decided to take a more direct approach in gaining the "Numbers" and dealing with the users of Zexal.

The Barian Pawn Threat At Dumon's request, Girag was the first to head to Earth to deal with Yuma and Astral. To this end, he started to use brainwashed pawns, starting with Fender and his gang of thugs. Meanwhile Yuma had a vision that someone has come to take his most precious something from him. This vision was realized when he learns that Fuma has captured most of his friends to draw out Yuma and Astral to get their numbers. Yuma, fearing for Astral's safety, left the Emperor's Key, along with Astral and the "Numbers" with Tori and ran off to school to duel Fuma. When the duel began, Yuma was able to hold his own and was even able to his Number 39: Utopia. However, Fuma used "Rank-Up-Magic Barian's Force" card and Summoned his "CXyz" monsters, "CXyz Mechquipped Djinn Angeneral", pushing Yuma into a corner, with Fender's army closing in. Meanwhile, Astral learns about Yuma's fight against the forces of Barian World and convinced Tori to take him to Yuma. Eventually Tori made it to the school and gives Yuma the key. When Astral appears, he tells Yuma while he's proud of his devotion to him, he also explains that it is important that they fight together as friends. With a combination of "Utopia Ray" and "Number Impact", Yuma and Astral managed to destroy Fender's CXyz monster and win the duel, while Fender's thug army was defeated by Kite and Shark. Girag disappears with the Barian's Force card, while expressing interest in the challenge the three and Astral will bring. With this attack, Yuma, Astral, Shark, Kite and co. becomes aware that their fight against Barian World has only just begun, but resolves that together, they can overcome anything the Barians can throw at them. Meanwhile, in the distance, a mysterious being in school clothes overlooks the gang and smiles.

Posing as a student, Girag continues to sends Barian pawns after Yuma and Astral to gain their "Numbers", while a mysterious new student named Rei Shingetsu quickly befriends Yuma, claiming he's a huge fan of his since winning the WDC. One of the attacks, Rio Kastle was threatened, but thanks to Shark and his bond with her, she was saved and fully healed. After she comes back to school, quickly befriends Yuma and co. and prove herself a skilled duelist when she helped ward off one of the Barians' pawn. Eventually, after seeing how Girag wasn't making much progress, Dumon sent Alito to assist him. While at first only interested in gaining Tori's affections, after dueling and losing to Yuma, he gained an greater interest in his rivalry with him, and ultimately became his first friend from Barian World.

Barian Cube Showdowns

Due to Girag and Altio's continued failures, Mizael is sent to deal with Yuma and Astral personally along with delivering two Barian's Sphere Cubes to Girag and Alito to allow them to duel at full power and have the ability to take the "Numbers" directly. Meanwhile Yuma begins to wonder if he can really protect Astral from the Barian's growing forces and their "CXyz" monsters after having a nightmare about losing to a mysterious and powerful dragon to the point where others began to see it. At his grandmother's request, Tori went with Yuma to visit the Duel Sanctuary. After learning from Kaze that Roku wasn't home at the moment, he also passed on two cards left by Roku, Overlay Chain and Overlay Bullet, just in case Yuma may need them. The next day, after being cheered up by Tori, they we're suddenly attack by Mizael, immediately demanding a duel. After accepting, Mizael used his Barian's Sphere Cube to trap Yuma and Astral and to be able to use his full powers.

In the duel, despite Yuma instantly summons "Number 39: Utopia", and equips "Overlay Chain" to protect its Overlay Units from "Rank Up Magic - Barian's Force, Mizael instantly prove himself a serious and dangerous duelist as he simply countered his strategy by summoning his own "Number" card, "Number 107: Galaxy-Eyes Tachyon Dragon", terrifying Yuma as it resembled the exact same dragon that appeared in his nightmare. Thanks to Tachyon Dragon"'s abilities, Mizael quickly overwhelms Yuma as he destroys "Utopia", knocking Yuma back into the Sphere Field and dealing real damage to him, causing him great pain and making him unconscious. As Yuma was too weak to continue the duel, Kite arrived and takes Yuma's place in the duel. It ultimately became a battle between the two users of "Galaxy-Eyes" with Kite challenging Mizael to a Duel between "Galaxy-Eyes" users which Mizael accepted. After Kite Xyz Summoned "Neo Galaxy-Eyes Photon Dragon" and destroyed "Tachyon Dragon", Mizael shed his human disguise, revealing his true form. He then Xyz Summoned his "Number C" through the use of "Rank-Up-Magic Barian's Force", resulting in "Number C107: Neo Galaxy-Eyes Tachyon Dragon". However, due to the sheer power of the monster, the Duel was interrupted as the "Barian's Sphere Cube" began to collapse under the pressure the monster generated. Mizael then returned to his human disguise and told Kite his name and that he will be the one to control both "Galaxy-Eyes" monsters, and then retreated. Astral's True Mission Revealed As Astral was contemplating how to defeat the Barians, he searched his memories for answers, only to run into Number 96 yet again, who told him that he hadn't completely regained his memories from the collected "Numbers" yet. As a result, Yuma and Astral were tested by The Door and the Shadow Giant to see if they were worthy of Astral's memories. The test was so difficult that Astral released Number 96 and told Yuma to use him. After they passed the test, Yuma and Astral discovered that Astral's true mission is to find the Numeron Code before the Barians do, as it has power to create and decide the fate of all reality. Afterwards,Yuma, Astral, and Number 96 were teleported outside of the Emperor's Key. Number 96 then abandoned Yuma and Astral, but not before telling him that he must become evil in order to defeat the Barians and find the Numeron Code.

Vector Returns At this point, everything was in place for Vector's secret plan to destroy Yuma and Astral from the inside. With that in mind he came back into the open to set his grand scheme in motion.

Despite losing to Yuma and Astral yet again, Vector tries to kidnap them. At the last moment, however, Rei steps in and gets kidnapped instead. Before disappearing with Rei, Vector gives Astral the "Master Key Beetle" Number card, saying it will open the door to their final faceoff (and Vector's perfect trap for Yuma and Astral).

Battle of Sargasso With "Number 66: Master Key Beetle" in hand, Astral is able to activate the Different Dimension Airship inside the Emperor's Key. Yuma decides to stage a rescue mission to Barian World to save Rei. He and Astral sets out, with Kite, Shark, Rio, Orbital 7 and the members of the Super Secret Number Cards Investigation Club in tow. As they make their way to Barian World, they come under attack by an army of monsters. Yuma, Shark, Kite, Rio and Bronk went outside the ship and use their respective ace monsters to hold them off, until they are all sucked into a black hole that sends them to "Sargasso", where Vector, Dumon and Mizael awaits.

Battle against Vector, the Barian manipulator: Round 2

Upon entering Sargasso Yuma finds himself face to face with Vector and "Rei Shingetsu" along with his friends watching him. Kite finds himself face to face with the other Galaxy-Eyes master and Shark finds himself face to face with the Barian master mind Dumon. Each of them in turn began by summoning their ace monsters only to be hit by the power of the field spell of Sargasso.

Yuma battled against Vector and the power of his Over-Hundred Number, which proved effective in countering "Utopia". Yuma and Vector continued dueling with Yuma extremely angry and distracted because of Vector supposedly killing "Rei", Yuma even argued with Astral. Eventually Yuma was able to blast Vector with enough power to destroy him with Number C39: Utopia Ray V, when this happened Rei even awoke from his slumber.

Shingetsu revealed himself to be none other than the Human form of the Barian Vector. Yuma did not initially believe Vector when he revealed this but eventually came to terms with it. When Yuma and Astral attempted to form into ZEXAL Vector turned Astral against Yuma by expanding the darkness within his heart from Yuma's betrayal. Astral initiated Dark Zexal with Yuma and the two of them nearly lost the duel, only avoiding it when Yuma ended Dark Zexal.

Seeing Yuma keep fighting made Astral realize that Yuma is still a friend and although he couldn't trust him as much as before they still had to win the duel. With their new found trust they combined into a newer and more powerful version of Zexal, Zexal II. The power of Zexal II was enough to change Rank-Up-Magic Limited Barian's Force into it's "True" form "Rank-Up-Magic Numeron Force" which defeated Vector and injured him. Due to the power released during the Duel however, "Sargasso" began to collapse, ending Shark's and Kite's Duels with no result. Before retreating, Vector warned Astral the dark stain in his heart did not disappear and will corrode his bond with Yuma.

While Yuma was dueling Vector Dumon dueled Shark and revealed his own Over-Hundred Number, Number 102: Star Seraph Sentry. It was enough to defeat Shark Drake for the first time with it's fierce power. Shark fought back but the duel ended in a draw, since "Sargasso" began to collapse.

At the same time Kite fought his own rival Mizael. Both of them were able to summon their respective Galaxy-Eyes monsters, Galaxy-Eyes Photon Dragon and Number 107: Galaxy-Eyes Tachyon Dragon. However when Kite upped the ante by summoning his ace Neo Galaxy-Eyes Photon Dragon Mizael responded by summoning his own Chaos Number, Number C107: Neo Galaxy-Eyes Tachyon Dragon. This was the first time Mizael had been able to summon the beast, however their duel was interrupted by the power of Zexal II, once again ending it in a draw.

Search for the Legendary Numbers
After Vector's plan at Sargasso failed, his hatred for Yuma and Astral reached dangerous new heights. To that end he sought out the power of Don Thousand.

Once Thousand was revived, Vector offered his life to him in exchange for the power to defeat Yuma and Astral. Thousand then explained that in order to be fully revived, he would need the power of seven sealed "Legendary Numbers" hidden on Earth. Vector agreed with Thousand and they merged, giving Vector new powers and fully healing him. While at first having trouble with Dumon and Mizael due to his failed plan at "Sargasso" making Yuma and Astral stronger than ever, he manage to convinced them to join him in the search for the Legendary "Numbers" with the help of Mr. Heartland, revived as a fly, due to the knowledge he gained from his time with Faker, along with mentioning the possibility of finding the missing Barian Emperors, Nasch and Merag as well. After the two left to start the search, Vector used his new powers to accelerate the healing of Gilag and Alit. Alit and Gilag had awoke later with their personalities twisted by Don Thousand

Truths that Connect Three Worlds

As Yuma and Astral hunted the Legendary Numbers down one by one, they discovered some legends tied to the Legendary Numbers. When Astral viewed the memories he obtained from Number 44: Sky Pegasus and Number 54: Lion Heart, he realized that the legends are of the Seven Barian Emperors past lives as humans. After seeing the Kastle twin's past lives in Number 73's & 94's ruins, Dumon and Astral suspect the Kastle twins to be Nasch and Merag.

In the meantime, on Don Thousand's orders, Vector made an alliance with Number 96, even giving him the means to access his Chaos form, along with allowing him to leave with Number 65: Judge Buster the Adjudicutter Djinn. Number 96's Last Stand and Astral's Sacrifice After mastering his new powers of Chaos, Number 96 was determined to not only defeat Yuma and Astral, but also destroy Astral World, Barian World and Earth as well. After launching an attack on the worlds, he summoned Yuma and Astral, along with Shark, Kite and Tori to his location into settle things with the Zexal pair once and for all. Despite the advantages he held from his "Chaos Field" Spell Card, one of which allowed him to steal two of Yuma's "Numbers" and have them Ranked-Up, Number 96 was ultimately defeated by the duo through using all three "Utopia" monsters and the power of ZEXAL II. After his defeat, Number 96 tried one last attack to kill Yuma and Astral. Astral took the blow and absorbed him, ending Number 96's threat once and for all. Before disappearing with the golden key, Astral thanked Yuma for everything and left the duty of gaining and protecting the "Numbers" to him.

Don Thousand's Master Plan unveiled With Astral gone and his "Numbers" in Yuma's care, along with the return of his missing piece of power from the shard that was within Astral, Thousand decided to get back to working on his master plan. After showing Vector to his old palace, he let Vector in on his goal. First he granted Vector four "Numbers", but told him that he would have to wait a while to use them against Yuma and showed him a device crucial to the plan. Using this device, Thousand would merge Earth and Barian World together, thereby allowing the malice of the human world to equal the malice of the Barian World, giving him all the power he needed to destroy Astral World. For this to work, he would have to make more of the devices, which was possible thanks to the power he regained from a shard that was inside Astral, the "Forbidden" Number 96: Dark Mist, thus Vector finally understood why Don considered him important. He then fused to Vector through the throne in the palace and after returning Mr. Heartland to his human form, gave him and the other members of the Fearsome Four of the Dark Dueling World the four "Numbers" in order to take the other "Numbers" from Yuma and his allies.

Fighting alongside the Arclight Brothers

The Arclight brothers later returned to Heartland, this time via a submarine where they discussed the ongoing war between the Astral World and the Barian World. With Astral gone, they knew that Yuma and his friends were going to need additional help in finding the Numeron Code and facing the forces of Barian.

Sorrow and the Company of III

For a time Yuma was deeply saddened by the loss of Astral. He barely left his house or talked to anyone, despite his friend's attempts to shake him. He got so bad that he heard Astral's voice such as when he attempted to get rid of the Numbers. Eventually Mr. Heartland decided to try and get him to hand over the Numbers when Semimaru took all his friends' memories of him. Yuma rejected the deal Heartland proposed and instead decided to duel with the Numbers on the line.

Yuma was not alone in this as he had help from an old friend in the form of Trey. Trey came to his defense with the power of his bracelet made by his older Brother. Trey told Yuma that he would become his "Shield and Sword". Yuma even gave Trey Number 33 and Number 6, the ones he had received from him before as he believed Astral would want him to share their power.Despite a heavy disadvantage Yuma and Trey dueled Semimaru and defeated him with Utopia combined with Atlandis. After the duel Yuma let Trey keep Number 3 they had received from Semimaru.

After the duel Trey continued to watch over Yuma.

Tribulations of the Twin Kastle Orphans

While Rio was still in the hospital Shark brooded over the memories he had been shown by Abyss in the Number Ruins. He rode on his motorcycle which prompted memories from his childhood about when his parents, himself and Rio were his by a car with him and his sister being the only survivors. He later appears at the front of his childhood home and remembers a time where he was injured and received a large scar on his shoulder.

Meanwhile Kurage, one of Heartland's associates from the Barian World attacked Rio to poison her. As he did he was discovered by Yuma, Tori and Trey. He told them he was after Shark and vanished. The three of them met up with Quattro, Shark's old rival and explained the situation to him, Yuma giving him Numbers 15 and 40. Quattro appeared to Shark who had also been poisoned by Kurage and the three of them began a 2 on 1 duel, Kurage having 8000 lifepoints, Shark and Quattro on 2000 each.

Shark and Quattro won the duel and beat Kurage who suggested that he had been familiar with Shark in the past. When he looked at him again he recognized him as the kid who was in the car when he ran into it years before, which according to him killed the whole Kastle family. As Shark approached a large fountain outside his old family home he seen the crest he had also seen in the visions of his past life, leaving Shark questioning himself more than ever if or not he is truly a Barian. Quattro got to keep Number 4 they had won from Kurage.

Open the Doorway between Dimensions

Behind the scenes the prodigy Kite and his master Quinton were working together to find a way to open the gate to the Astral World. After finding the place where a gate could be built they got to work on it and built the gate. After that they alerted Yuma who, accompanied by Tori came to where they had build the portal and Kite explained that the Conqueror's Coins they had found at the each of the ruins were the key to opening the door to the Astral World, being left behind by Yuma's Father in case he ever had need to go there. While gate was just about to be activated someone attempted to shut down the power. Thinking quickly Kite plugged Orbital 7 into the gate to power it back up.

In the meantime another of Heartland's assassins appeared in the form of the Mosquito Ninja, another being from the Barian World. Yuma stepped up the challenge to duel him, however Kite and Quinton quickly stepped in with Quinton even regaining Number 9: Dyson Sphere in the process. While Orbital powered up the gate.

In a showdown between Galaxy-Eyes Photon Dragon, the Number Slayer and Number 9, the largest number and Number 2, the smallest Number the three of them began a 2 on 1 duel like before with Kite and Quinton on 2000 Life points and Mosquito Ninja on 8000. Mosquito Ninja managed to infect Kite with a virus that made him believe that his partner and opponent were infact the opposite person. Eventually thanks to Quinton's quick thinking and a larger version of Galaxy-Eyes they managed to defeat the assassin and send Yuma to the Astral World, Tori giving him a farewell.

Journey to Astral World

Thanks to the support of Kite and the gang, Yuma is able to reach the Astral World. When first touching down, the plants came to life when he touched them. He comes immediately under attack by the will of Astral World itself, Eliphas, seeing Yuma a a dangerous entity. But he is able to escape thanks to the assistance of his new aid and guide, Rainbow Kuriboh. Yuma eventually meets a citizen named Ena, who helped saved him from Eliphas' wrath because everyone wants him to be saved. Ena explains the history of Astral and Barian World to Yuma, and how he contains the Power of Chaos that can heal everything and turn the world into a stronger place again. Ena also reveals that the reason why the shining figure, Eliphas, was chasing Yuma is because of his powers. As Yuma and Rainbow Kuriboh continue their journey to find Astral, Eliphas appears before everyone and Ena, who tells him that she saved Yuma. By doing this, he saved everyone and that he is here to save Astral and this world.

Facing Astral World's Will



Yuma finds Astral in a glass tube, resting from his injuries and tries to wake him up. Eliphas officially introduces himself to Yuma and tells him it's no use trying to wake Astral up and he will not allow him to take Astral because he is the only one that can Rank-Up and destroy Barian World. Eliphas blames Yuma for Astral's current state, but Yuma counters with saying that even it was true, they still fought together as friends.

Yuma then challenges Eliphas to a Duel, saying that if he wins, he gets Astral back, but if he loses, he’ll lose all his memories of Astral. Eliphas accepts the Duel and the conditions at stake.

Nasch Reincarnated

While Yuma was away at the Astral World, things were still moving on Earth. In the Barian World Dumon spoke with Mizael about their part lives as humans and also about Nasch and Merag and his findings at the ruins. Mizael admitting that he was right. Dumon is determined to get Nasch back by whatever means Necessary. He then leaves and confronts Shark in the hospital with Rio, calling him "Nasch".
