Onizuka, Kenya

鬼塚剣哉

Onizuka Kenya, the resident bully and delinquent of Class B, was originally from Class A but was demoted due to his bad behaviour. He had a run-in with Akatsuki and Miu on their very first day at Babel, and he has been at odds with Akatsuki ever since, though he eventually grows to grudgingly respect Akatsuki in the end.
He makes use of fire magic, and his weapon of choice is the chakram.
