Sayuri Akino

Tsubasa and Minami's classmate who, with her raven-hair, reserved personality and choice not to use the Hokkaido dialect, is the exact opposite of Minami. She is very into video games, but pays attention to her appearance; reading fashion and make-up magazines in order to fit in. Because she sweats a lot, Sayuri avoided all forms of exercise, which eventually found her avoiding people in general. Because she has no friends, Sayuri felt a kinship with Tsubasa, and she becomes friends with him and Minami.
