For Chitose Hototose, life has never been more full. Being the “adopted” son of not one, but five of your teachers can’t be easy! His “moms” are: Ichimonji Mutsuki, classical writing and ultimate housewife, Shitennou Uzuki, fine arts and cosplay otaku, Sanzein Yayoi, school nurse and accomplished miko priestess, Gokajou Satsuki, phys. ed. and all-round Gorilla, and Ninomai Kisaragi, mad scientist. But when a mysterious person appears and demands the return of “Muuchin”… well that’s just the beginning! What’s a boy to do when maternal instincts go wild?
