riot

You are Akiro, a fifteen-year-old boy. At the beginning of the year, Akiro transferred to a new school. His new classmates took a dislike to the newcomer and bullied him. Akiro hated his tormentors with all his heart. But there was one among his classmates who didn't bully the boy. One fine day, after classes ended, Akiro headed home. But he never made it. As Akiro was walking down a deserted street, someone suddenly approached from behind and knocked the teenager unconscious.
Akiro woke up in some kind of damp basement. His hands and feet were tied.
-Mmm!- the schoolboy groaned.
-Awake, sweetheart?- a familiar voice asked.
Akiro looked fearfully toward the window to see who had spoken. It was Riota.
