Constellation:

Sagittarius

Character:

A short first year student who often has overly long sleeves. Due to her short and skinny stature, she often has trouble finding clothes that fit her. She has been friends with Run since kindergarten, often getting lonely when separated from her and threatening anyone who tries to make a move on her. She disliked Yuko at first, since her first impression of her was seeing her in a compromising situation with Run, and since then constantly teases her at every opportunity. She has a pet cat named Tansan.
