Sakamoto Kanako

Kanako became the homeroom teacher of class 2-B, after their previous homeroom teacher was hospitalized into a mental institution as a result of dealing with this crazy class. Also, this is her first job as a teacher.

She enchants her male students with her large breasts and with innocent, but mature charm without realizing it.

Kanako treats Yoshijirou as if he was her younger brother, and she also takes Yoshijirou's side on the competition.
