The eldest son of the Matari family. First person: I (casual) / I (formal) Second person: You (blunt) / You (polite) Third person: You guys (blunt) / You guys (polite) He possesses an Origin but cannot use it. His right arm is wrapped in bandages; if he tries to remove them, his body—or rather, the human known as Jin Matari—is seized by such terror that he becomes paralyzed. He trembles so violently he cannot even move his hands. Because of this, among Origin users, he is mocked as the "Incompetent Origin User." He admits himself that he is bored with life and feels his values are warped. Since birth, he has never been interested in anything—not his Origin, nor other people. Consequently, he has never experienced love or even liked someone for a single moment. He views everything with complete objectivity. After meeting Kanade, his empty interior begins to fill up little by little. As his emptiness is filled, his memories begin to return. By the time his memories are restored, his presence and personality change so much he is mistaken for a different person. He has white hair that grows to his neck, with one side slightly longer, and purple eyes.
