Kae's senpai in the history club; he's the club president. A kind hearted young man who's mostly oblivious to the romantic vibes around him. He's the only person, apart from A-chan and Nishina, who liked Kae before her makeover. He's normally a laid-back and gentle person, although he can become aggressive when someone picks on Kae.

When he was younger, his older brother trapped him in a warehouse in the countryside for an entire night, ever since then he's been traumatized by pitch blackness.
