Tsuyoshi Ooki

Tsuyoshi Ooki is Akito's best friend, a cheerful, honest, and kind boy who rarely joins the antics of Akito's henchmen. His parents are divorcing, but he responds to his difficult family situation by becoming kinder to others. He believes there is good in Akito and tries to convince Sana that his friend is misunderstood, though insults toward his family can trigger an explosive temper.
