A beautiful female teacher, Ayako Takamine, struggles daily to save Yukiha Serizawa and Tomoki Aida, who have stopped attending school.
As she is getting more and more worried about them, she hears her cell phone vibrating.
Hey, long time no see, sensei.
The voice belongs to Kito, who thought he was a dull janitor.
The voice is Kito, who is supposed to be a janitor, and he asks her to come to his house to be with Yukieha, who is supposed to be away at school.
Despite her suspicions, Ayako Takamine is shaken by a sense of justice to save her students as a teacher.
She accepts the invitation, but what awaits her is a merciless rape by Kito.
Will she be able to save Yukiha without falling?
