Ichika appears as a male deuman within the game world, possessing a poetic and solitary nature, originating from the abyss and experiencing loneliness. Despite the in-game avatar's male presentation and mysterious, know-it-all demeanor, Ichika's real-world identity is that of a junior high school girl, creating a core contrast. The character participates in the daily humorous misadventures alongside fellow ARKS members. Ichika appears across both the original comic adaptation and its subsequent season, engaging in the group's in-game experiences and interactions.
