With this new original story set before the arrival of Hayami Takuro, the protagonist of the first series, the hit anime series Discipline is brought back to life. At St. Alcadia Academy, Leona Morimoto and Saori Otokawa are new boarding students. Leona Morimoto wants to subjugate everyone at the school, punishing those who aren’t useful to her. Teachers aren’t exempt from this. Yuuki, Ruri, and Maiko, who are completely unaware of the scenario, become victims of the male students’ insatiable sexual urges.
