Toudou Rin

A Strict but Naive Oni Sergeant-Senpai

Zodiac: Aries

A senpai at Acacia Academy, she is Yui's squad leader and instructor. An oni who imposes strict training and life lessons. At first glance, she seems mannish and determined, but there are rumors that she is surprisingly a maiden at heart......!? In the dormitory, she shares a room with Yaeka, and has a hard time dealing with the cheeky kouhai.
