Jin Tojo is Basara Tojo's father, a Japanese photographer by profession. He stands 1.83 meters tall with brown hair and brown eyes, bearing a facial scar as a distinctive trait. Jin is frequently depicted wearing glasses and slippers while smoking a cigarette. He appears at the series' outset when he and Basara await Mio Naruse and Maria Naruse, Basara's soon-to-be stepsisters, at a restaurant. Shortly after this meeting, Jin departs on a business trip, leaving Basara to live with Mio and Maria. This early exit establishes the initial family dynamic without Jin maintaining a consistent presence in the household. He later features in a flashback sequence during the BURST season, though the flashback's context remains unspecified.
