小鳥遊 圭

Kei is a strange girl in Mizuho's class who usually has a quiet voice and doesn't show much emotion which often gives her a creepy visage. She is the director of the drama club and during times on stage she has to be very forceful in order to get a good response out of her actors. A character with the same name and similar appearance,Takanashi Kei, appears in Alicematic, a game made by Caramel Box (the same studio that created Otoboku).
