Son of Enishi, (missing) eldest brother of the Itoshiki siblings. He currently hangs around with his uncle Nozomu and looks up to the latter's student and de facto caretaker Komori Kiri. Like his uncles and aunt Rin, Majiru's name, when compressed, has another meaning: "絶交" - "zekkou" ("breach in relationships") - hinting to the fact that he has to live with his uncle.
