History and Crime
Kyousuke was born in a totally normal family, and grew up a regular boy.

Since his agressive defense of Ayaka, he gained a reputation as a fighter, becoming targeted by many opponents.

This bad reputation of his led him to be targeted by Purgatorium Remedial Academy, who framed the boy for the murder of 12 people. Thus, he was trasferred to the school.
