Ai

アイ

The "Dark Ignis" (闇やみのイグニス, Yami no Igunisu), also known as Ai, serves as the deuteragonist in the first and second seasons.
Dr. Kogami, the scientist behind the creation of the Ignis, created Ai. The Ignis were developed by observing the six test subjects Duel, with Ai modeled after Yusaku Fujiki. Eventually, Ai and the other Ignis evolved and created the Cyberse World, along with the Cyberse monsters.
Their progress worried Dr. Kogami, who had created the Ignis to help humanity and predicted through his simulations that the AI and humanity would become enemies.
Despite this, Ai and the other Ignis continued to create their world, each with a sector based on themselves. In Ai's words, the Ignis would never try to harm humanity, and would rather live in their own world
