A self-described cheapskate with an encyclopedic knowledge of just about everything—especially anything remotely perverted. He's been tight with Naoya Nifuji since they were kids in kindergarten, and that friendship has basically defined his entire social life. Fans often note his unapologetic approach to his interests, which he doesn't really hide or apologize for. He's the type to know obscure trivia and isn't afraid to share it, no matter how awkward the situation gets.
