Melancholy, unmotivated Ayanokoji Kiyotaka attends his first day at Tokyo Metropoiltan Advanced Nuturing High School, a government-run institution where everything is decided based on merit, including the students' generous monthly allowances.

Thanks to a lot of hard work and scheming, Class D managed to get surprisingly high scores on their midterm exams. But when a student fails a single test, Ayanokoji makes one final play to save his classmate from expulsion.

With the hearing for the assault approaching, Ayanokoji and Kushida attempt to secure the cooperation of Sakura Airi, possibly the only person who can testify that Sudo was acting in self defense.

Sakura's testimony has bought Class D time, but Horikita and Ayanokoji still need to find a way to tilt things in their favor. Meanwhile, Sakura senses the presence of a strange man nearby.
