Anime XXX - Oshioki Gakuen Reijou Kousei Keikaku 02 Unc

Shimohei Joutarou is my name. Regardless of the fact that the school year has not yet began, there's a purpose I'm here, at my new workplace. I pretty quickly found Mitsuki and Minami's secret on that first day. Then I learned about Mahiru, the sister of Classics teacher Kuji Hinako, and her remarkable student achievement. Hinako's backdoor maneuverings are then disclosed to me. It is now my duty to rehabilitate these students who have broken the rules.
