Kyousuke "Kyou-chan" Sayama

About

Kyousuke Sayama has just graduated middle school with no regrets. He does anything he wants, and doesn't really take risks. He discovers that he has the ability to restart a day in order to save a girl from making a decision that she'll regret.


On the day he would graduate, he commits suicide by jumping off the school's rooftop.


He then restarts the year all over, initiated by his Chihiro, who thinks he committed suicide because he didn't live highschool to the fullest.

Later it shows that he commits suicide because either him, or one of the girls he had come to be friends with would have to die, and he sacrificed himself.
