Direct and headstrong, Otome Katou
is a student in year one, class four, who like Nanami, is a member of the girl's basketball team. She is usually authoritative to her peers, tolerates nothing but her way and opinion, and does not generally associate with anyone but her trio of friends Minami Obuchi, Natsumi Koizumi and Kumi Mori; who together frequently harass and coerce Kotonoha. Despite her difficult behavior and personality however, Otome can be particularly tender and shy, especially around Makoto, who she has known since junior high school and has a crush on. Otome has a younger sister named Karen, who appears in Summer Days. Her birthday and his surname is derived from Katō Tomosaburō.
