A brown-haired nun wearing glasses. A lethargic, downer sister. She has wide, child-bearing hips. First person: I (Watashi - masculine, blunt) She rarely initiates action toward the protagonist, but she tolerates whatever actions the protagonist takes. One could say she finds it too much effort to refuse and deal with persistent advances. Her hobby is sleeping. Her catchphrase is "What a pain..." She has no faith, so her prayers are half-hearted.

A blonde nun. A sister with a gyaru-like vibe. First person: I (Atashi - casual, feminine) Gyaru-style speech. Hedonistic and accepts everything with a laugh. She always seems to be having fun. Her hobby is drinking. She drinks from broad daylight. Nobody stops her. Her catchphrases are "Cray" and "Totally cray." She has no faith, so her prayers are half-hearted.

A black-haired nun with glasses. A sister with a politely insolent attitude. The eldest of the group. Large-breasted. First person: I (Watashi - polite) Uses honorific speech. Her hobby is teasing men; she initiates physical contact or plays pranks on men who visit the church to mock them. She does this fully expecting a counterattack, so if she is retaliated against, she will feign dislike in a monotone voice while remaining completely passive. She has no faith, so her prayers are half-hearted.

A silver-haired nun. A sister who is always smirking. First person: I (Watashi - cheeky) Speaks like a bratty kid. A nun who loves money and gambles constantly. She will take any kind of bet. She has a slight self-destructive streak and gets excited when backed into a corner. She will do almost anything if paid. She spends her money on things like beauty salons. She has no faith, so her prayers are half-hearted.
