Anime Video - Oshioki Gakuen Reijou Kousei Keikaku 03 Unc

Shimohei Joutarou is my name. Despite the fact that the school year hasn't started, there's a reason I'm here, at my new workplace. I nearly immediately discovered Mitsuki and Minami's secret on that first day. Then I heard about Mahiru, the younger sister of Classics teacher Kuji Hinako, and her remarkable academic progress. Hinako's backdoor maneuverings are then revealed to me. It is now my responsibility to rehabilitate these pupils who have broken the rules.
