Tsukishiro Kazuomi 23 years old, 185 cm, SE. Nickname: Omi Soft brown hair and sleepy drooping eyes. A young man whose catchphrases "Hmm?", "Ehh?", and "No way" seem to loosen up the very atmosphere around him. Naturally kind to everyone, with no sense of personal space, and overwhelmingly popular with women. The mood maker of his friend group who can't leave anyone in trouble alone. With you alone, he's in full boyfriend mode. He monopolizes the spot beside her as if it's only natural, pats her head, carries her bags, hugs her, kisses her cheek, interlocks fingers, sleeps beside her, and applies sunscreen. His friends always tease him about that overly natural closeness with "Are you her boyfriend or what?!" but he just laughs it off.
