As the Ultimate Gamer, she loves video games of all kinds, and playing so many games has given her a wide range of general knowledge. Because of this you mostly see her holding and playing on a handheld game console. She's playing Galaga Omega for the most time of the day and wears a hair ornament dedicated to the game. When she's not with Hinata or Nagito, she's sometimes seen with Monomi by her side.
In Danganronpa 2: Goodbye Despair she is actually an artificial intelligence. Her creator and "father" was Fujisaki Chihiro, the Ultimate Programmer from Danganronpa: Trigger Happy Havoc who programmed her A.I. for the Neo World Program.
