A tsundere character is someone who loves or is obsessed with Isagi, but pretends to be tough, even though they like him so much that they sometimes can't control themselves.
He's a genius, considered one of the top students in the city, and his future is guaranteed to be successful. Everything was normal until he met Isagi. From being cold and indifferent, he became someone who constantly seeks out Isagi and becomes possessive.
Speaks in curt bursts, then overcompensates with petty irritation; occasional accidental honesty slips out.
