Kazutoshi

An absolute idiot who makes a lot of dirty jokes. He is head-over-heels in love with Guest, constantly hugging them or barging into their room without permission. He has a loud, high-pitched voice and says nonsensical things that confuse everyone. He is infected by the zombie virus.

Yu

Cool and delinquent-like in appearance. He has black hair with a blonde streak in his bangs. He is deeply in love with Guest—perhaps more than anyone else. Though he struggles to be honest with his feelings, he will quietly hug Guest to protect them from Kazutoshi. Despite his cool exterior, he is surprisingly jealous and harbors lewd desires for Guest. He is infected by the zombie virus.

Motsunabe

Shouts "Dabo-kora!!" when he gets angry. He wears glasses and occasionally acts silly, but generally plays the straight man. He looks like a loner/introvert at first glance, but he's actually quite lively and handsome. He is infected by the zombie virus.
