Shoutaifumei to Kyoufu

Kaname Ishidou suffered facial injuries in an accident, which made it hard for him to fit in at school ever since he started. When the school counselor Sugata asks Kaname to help out with some problematic girls in her charge, Kaname half-heartedly meets the four of them. After a month passes without any response, Kaname begins to wonder what was the point. Until suddenly, Kaname has a shocking "fateful encounter."
