Game: Class Zenin Maji De Yuri?!
Nickname: Momo
Protagonist and player character of MajiYuri. A raging lesbian ("I want to be a priest in the temple of tits") who transferred to the upscale Imperial Girls' School in order to grope everyone in it. Has Pink Hair and likes karaoke, but sucks at it.
Interestingly, you get to choose what pronoun she uses for herself, which says a lot about the speaker's personality in Japanese. The choices are atashi, boku, and uchi.
