Character

Umi Mamizuka

まみずか

Umi Mamizuka, is the P.E. teacher at Morinomiya Academy's high school, the wife of Mamizuka Kousuke and the mother of the twins Takuma Mamizuka and Kazuma Mamizuka. Like Takuma, Umi has a bright and bubbly personality. Ever since she was a young child, Umi has rarely been seen without a cheerful smile on her face. She has a generally more relaxed and calm approach to parenting, especially when compared to her husband, Kousuke. She is a very maternal and comforting presence to her son, Kazuma, who cries easily. Umi cares a lot for her family, letting her eager sons run their first errands by themselves (with Kousuke following them to keep them safe). She trusts her husband greatly, especially when he felt guilty for having to kiss other women as an actor.
