Sumire Karino 狩野菫

Tadashi's mother, age undisclosed, is the director of Private Hakusen Academy. Little is known about her and she never appears in front of the students. A woman whose actions speak for themselves, she is strict and intimidating. She is the primary reason why Tadashi entered the SA class and has threatened to punish him if he gets a lower rank than fifth place. In the past, she frequently punished Tadashi when he failed to please her and does not hesitate to do so in the present when he offends her, often extending the punishment to the rest of the SA if she deems fit. She and her husband were really popular in school when they were still students. As Tadashi stated, his parents always had a boyfriend and girlfriend.
