Mafuyu Shimotsuki

A chemistry teacher at Sakuraba Girls' High School, and subsequently the homeroom teacher of Akiho, Haruka and Akatsuki's class in their second year. She is the advisor of the kyūdō club, but she is not that skilled at it. She is childishly innocent, but she speaks very politely. She has the appearance of a 7-year old grade schooler with brown hair, tied on the left side of her head. Though the reasons for this is unknown, she apparently has a license to cook fugu.
