How to Eliminate My Teacher

High school teacher Tsuneo Yoshizawa arrives at Teisen Private High School on a collision course with the four student ringleaders in Class 3-D.

Assistant homeroom teacher Asahi Yorita schemes against Tsuneo, manipulating Toya and Nagi into leading an effort to eliminate him.

Frustrated by Nagi's failure, Toya turns his machinations on Yumi, who's been in love with him since an incident with her mother two years ago.

Toya gets so angry that he tries to stab Tsuneo, but Asahi manages to stop him. Instead, Toya tries to kidnap Tsuneo's girlfriend from the hospital.

While the four students are wracked with guilt over Tsuneo's fate, Asahi happily takes over as the homeroom teacher for Class 3-D.

Tsuneo returns, but the only thing he seems to remember is his desire to have revenge on the four students who wronged him.

The four students tell Asahi about Tsuneo, but he has difficulty believing them. Nonetheless, he gets the riot police to go after Tsuneo.

Tsuneo regains his memories only to find himself at Asahi's mercy, with Shizuka held hostage to ensure his compliance.
