川原 瑞葉

Yuu's cousin and Touka's elder sister. Yuu was always looking up to her, so he was very happy when she adopted him after he lost his parents. Mizuha also works as a teacher at the school characters attend (出水城学園), where she's very popular (especially among boys). On the other hand, her housekeeping skills are nothing but a disaster. Whenever she tries to cook, it ends up in lots of smoke, and when she tried to clean the bathroom, allegedly the bathtub had exploded. She wields deadly 48 variations of dekopin (poke in the forehead), and uses this killer technique to solve most of family disputes and problems. Her hobby is teasing Yuu with seductive attempts, which causes him lots of headaches recently. [adapted from character introduction in manual]
