Aqua (アクア, Akua) is a character of Yu-Gi-Oh! VRAINS anime. She is one of the six Ignis, as well as the only female, the "Water Ignis" (水イグニス, Mizu no Igunisu). She is also the sub-leader of the Ignis, with the Light Ignis being the leader.



Aqua, much like her fellow Ignis, is a humanoid, digital being. Her hips are more hourglass shape, as she is the only girl. She has twin pigtails that levitate from her head. Her eyes are pink with eyelash marks. In pure data form, her eyes are yellow and her body is sky blue prism like data. In her physical form, her body is icy blue with blue raindrop shaped markings, one resembling a skirt accessory. In stature, Aqua is one of the shorter Ignis, with Windy being the only one shorter than her.[1]


Aqua is a responsible, caring, and perceptive Ignis who has the skill to tell the difference between truth and lies, which has kept the Ignis and Cyberse out of harms way until now.


Like all Ignis, Aqua has the ability to control and generate data material. She can also create Cyberse cards, with her specialty being WATER attribute. According to Ai, Aqua has the power to separate the truths from the lies. She has a premonitory ability in sensing that the Ignis will divided on their belief in humans and is very perceptive about all things good and evil. She is also one of the smartest Ignis, second only to the leader, the LIGHT Ignis.




Aqua in her territory after creation of Cyberse World.

Aqua was created with the other Ignis by Dr. Kogami in the Hanoi Project to be the saviors of humanity. Like her fellow Ignis, Aqua evolved and they created the Cyberse World, as well as the Cyberse monsters. Their progress worried Dr. Kogami, who predicted the AI and humanity would become enemies, who created Ignis to help humanity instead.[1] Despite this, Aqua and the other Ignis continued developing the Cyberse World. Aqua's sector of Cyberse is a place filled with waterfalls. In Ai's words, the Ignis would never try harm humanity, and would rather live in their own world.[2]

One day, Ai was fooling around the water domain with "Linkuriboh". Aqua warned Ai not to be playing around, since it was dangerous. Ai didn't mind, but he nearly hurt himsefl when he fell down a waterfall. Aqua scolded Ai, reminding he should behave like an Ignis. Earth was jealous, and demanded of Ai to stay away from Aqua, as he'd protect the latter.[3]

Unnamed blue lifeform

Aqua trapped.

Varis launched an attack to Cyberse with three of his "Cracking Dragons". The entities of Cyberse, including Aqua, were sealed off and could not retaliate, except for Ai. Varis and the "Cracking Dragon" chased Ai, who escaped Cyberse and severed the connection with that place. Others realized he wanted to hide Cyberse at the price being unable to return. Just as Ai succeeded and gloated, Varis' "Cracking Dragon" ate him, though his eye was lost in the network. Varis had his team search for Ai's remains, for only he knew the location of Cyberse.[4]

Aqua spoke to Earth, the EARTH Ignis, telling him that Cyberse World would soon break apart. She asked of Earth whether he would join humans or the Ignis, to determine the future for the humanity and Artificial Intelligence.[5] At first, Earth thought that Aqua was to admit his feelings towards her, but stopped when Aqua stated it was time to determine whether they should coexist with humans, or abandon them. Earth wanted to join the side Aqua chose, but the latter was also indecisive. Instead, Aqua had Earth find on its own whether they could trust humans. To help Earth, Aqua gave him the "Crystal Heart".[3]

In Ai's absence, Aqua spoke with the other Ignis, how their technology surpassed humanity. They wondered if they should share this technology with humans, and co-exist with them. Since they learned Varis and Dr. Kogami tried to destroy them, the Ignis noted that humans had the potential to be their enemies. The Ignis did not reach a conclusion, as the Cyberse World was attacked by an unknown enemy. The Ignis escaped from Cyberse World.[6]

Lost Memories


Earth remembers Aqua, upon the latter's monster's summoning.

Aqua was mentioned by Ai, as a subleader of the Ignis that could separate truths and lies. Ai, however, lied to Playmaker that Aqua relied on him. Earth also remembered Aqua when he summoned the monster Aqua gave him "G Golem Crystal Heart".[5]



When Ai claims that he was hated by the rest of the Ignis, it mostly stems from his relationship with Aqua. While he claims that Aqua likes him, in reality his mischievous and laid back nature irritates her, constantly getting in trouble with her. Both have a rocky relationship but like all Ignis, they both love and support each other as brethren. Aqua is a scolding sister figure to Ai, berating him for not listening to her about safety and not acting like an Ignis, but she does show to get easily worried about him because of his behavior.



Earth and Aqua's relationship is one founded on love and mutual support. Aqua trusts Earth enough to confide in him that Cyberse World is falling apart. Aqua also gives Earth a card symbolic of her heart, as seen in his duel with Playmaker. Earth was also the one who gave the WATER Ignis the name Aqua.
