Kyoji Yagumo

Kyoji Yagumo is one of the major antagonists in the Yu-Gi-Oh! ZEXAL manga. He is a Numbers Hunter, and was raised in an institute together with Ryoga "Shark" Kamishiro.

Appearance
Kyoji's pupils are vertical, and his eyes are light brown. He has raised, gray colored hair with one wick of green colored hair falling over his forehead, and green hair near his neck as well. In the past, his hair was lowered down to his neck and was much shorter, and he wore less extravagant clothing. The embroidery in Kyoji's attire is shaped like a spider, and the orbs accentuating his collar resemble its eight eyes.

Personality
In the past, Yagumo appears very happy, sharing a trophy with the other orphans and Shark. In the present Yagumo maintains a fairly calm demeanor, and at first appears strongly loyal to Dr. Faker. However, beneath his general calmness Yagumo is extremely cruel, punishing His Subordinates with harsh penalty games for failure.

He later shows himself to be nihilistic, claiming that he believes that the world is deserving of destruction and there is no value in its existence.

Abilities
Kyoji can implant small spiders into the hearts of other Duelists. He calls the spiders his "pets". When the Duelist is no longer of any use to him, he can use the spider to perform a Mind Crush. He can also build huge spider webs and fly with spider legs growing out of his back.

Kyoji has also shown a very unique ability: when a blank "Number" makes contact with a human, it takes form after its owner according to their desires; however, Kyoji himself claims that he has no "desire" of any sort. This allows him to mold his blank "Numbers" freely in response to his needs, making Kyoji himself unaware of the extent of the power of his "Numbers".

Etymology
"Yagumo" is written with the kanji for "cloud" (雲, Gumo), which has the same pronunciation of "spider" (グモ/くも, Gumo/Kumo); puns involving the two words are very common in Japanese. This could be a reference to Koji Nagumo, who besides having a very similar name, also had the nickname "The Spider".

History
Kyoji was raised in an institute together with Shark. He and Shark were like light and shadow there, but they weren't on bad terms.

Once, both he and Ryoga entered the Duel Monsters Regional Cup. At there, Kyoji wanted to steal the Deck of the person who was most likely to win the tournament, but failed, and Shark took the blame for it.

Yu-Gi-Oh! ZEXAL
Kyoji became Number Hunter, hired by Mr. Heartland.

At the conclusion of Yuma Tsukumo's Duel with Eviluder, Yagumo appeared supported by spider webs, introducing himself to Yuma, Shark and Kaito Tenjo as the commander of the "Numbers" collecting operation and that he'd soon be taking their Numbers. He told Eviluder that the moment he became Yagumo's subordinate, his "pet" already haunted his heart. Saying he must punish the loser, he uses the spider he had planted in Eviluder's heart to perform a Mind Crush. Yuma complains to Kyoji, who tells him he should worry with himself before the other. He asks Yuma if he really thought he could survive that fight, the "Numbers War", against him, Shark and Kaito, and told he is certain to win. Shark asked what he become and Yagumo said that Shark's gotten rude since last time they met, asking away personal questions already. He then tells him hope and despair are two sides of the same coin - the more hope a person has, the deeper their despair will be. He ends by saying that Shark's important to him, and that someday he would teach him what that means. Spider legs then grow from Kyoji's back and he leaves flying.

Kyoji anticipated Kaito taking his brother Haruto to safety, so he set up a spider web trap for Kaito. He then contacted his second Numbers Hunter, Hishakaku, and told him it was his turn to go out and hunt the Numbers. Kyoji then appeared to Kaito after he fell for his trap. He was then challenged by Kaito to a Duel, but instead of accepting said challenge, summoned Hishakaku to Duel Kaito. He then spectated their Duel and watched as Hishakaku committed suicide and tried to take Kaito with him.

After Hishakaku's defeat, Kyoji Yagumo dispatched his third Numbers Hunter, Shadow to deal with both Kaito Tenjo and Ryoga Kamishiro by allowing both Numbers Hunters to defeat him, allow each of them to take a Number from him, and then pit the two against one another.

After Shadow's failure, Kyoji decided to betray his employers, Dr. Faker and Mr. Heartland. He told Mr. Heartland that he'll be following his own plan to destroy the Astral World, which angered Mr. Heartland to the point of them Dueling each other. During the Duel, as Kyoji activated his "Court Battle" card, he claimed that Mr. Heartland was to be prosecuted for his "sins" and that Dr. Faker was already dead.

As his and Mr. Heartland's duel continued, he elaborated on his earlier claim by calling "himself" to the stand. He then revealed a clone made up of small spiders ejected by "Number 70", which he was able to link his vision with. He explains that over the past year, no one had been allowed to see Dr. Faker in person, leading him to suspect something was amiss. He used his spiders to infiltrate Faker's lab and found a video recording made by the doctor as part of his research logs. In it, Faker remarked that after 1 year and 15 days since he began his attack on Astral world, he had made no progress, and his health was in rapid deterioration. Like his son, Faker was beginning to succumb to his own incurable illness and recognized that he did not have long to live. He claimed his only regret was that without him, no one would be left to cure his youngest son.

From this, Yagumo realized that Faker was nothing more than a "pitiful father trying to save his sick son" and his natural death was being used by Heartland. Heartland continued to resist these charges claiming that he had nothing to gain. However Yagumo explained that Heartland's real goal was to steal the valuable limitless energy machine Faker was developing, in order to amass wealth for himself. Thus Heartland hid Faker's death from everyone– even Faker's own children.

Heartland maintained that Yagumo's charges were baseless, and began using his Heart Monster effects to gain a quick life point advantage over Yagumo. His Mind X-ray ability revealed that Yagumo's power deck posed no threat to him and passed turn to Yagumo. Yagumo then revealed his Rank-Up spell card, using it to summon Number 14: Sarameya the Greed which made short work of Heartland's monsters. Heartland reacted in surprise, as that Number had not previously existed in Yagumo's deck. He scanned once more, again finding no threats. Heartland responded by summoning his Number 52: Diamond Crab King, which fails to destroy "Sarameya."

Heartland then asks Yagumo how exactly he "used" Faker. As Yagumo draws, he explains that Faker had relied on a special medication to prolong his life. Heartland had used his connections with Faker to hack the databases of the pharmaceutical company that made this medication to find other victims to swindle. He calls Heartland out as a common con man who made his living by working his way into the confidence of those near the end of their lives to take their fortunes– with 689 victims total.

Yagumo then activates Rank-Up Spider Web a final time, choosing to summon a Blank Number. He reveals that all numbers take forms that fit the desires of the duelists who hold them. However Yagumo's only desire was to see the world destroyed– a desire he calls "a wish as insubstantial as a single spider's web drifting on the wind." Thus all of Yagumo's "Numbers" remain blank as long as he holds them, only taking form when summoned in a duel. His Numbers thus evolve to fit whatever situation Yagumo finds himself in– he always has whatever card he needs in a duel. He then transforms the blank card into Number 21: Frozen Lady Justice, which destroys all of Heartland's defense mode monsters and used the effect of Court Battle to win the duel. Yagumo finally exclaims that Heartland's real sin was not that he had merely deceived the duelists in Faker's employ, but that he had stopped the attacks on Astral World for fear of the destruction of Earth. Yagumo insists that the world deserves destruction and there is no value in its existence.

Deck
Kyoji plays a Spider-themed Insect Deck, focused on swarm tactics to quickly Xyz Summon his "Numbers", which he molds himself according to his current needs. According to Heartland, Yagumo's deck is very simple and relies only on brute force to win.

Accessible "Numbers"
Kyoji is known to have access to at least 8 "Number" cards.
