Narita Gumi

Fetish: Phallic Servicing
Weak spot: Toes

Yuzuki's retainer. Her family has served the Ryuugasaki family for generations, and because of that, she is now serving Yuzuki, but Gumi isn't an "ojousama" herself and is only permitted on the school because of her position.

She loves phallic objects, large penises and long sex. When she saw the protagonist having sex she fell in love with his penis instantly, as if it were a matter of course. Her weak spot is her toes and be servicing or being serviced, if it's about her toes she'll like it. Also phallic objects excite her so much she loves giving service to them with her mouth, vagina or any other body part.

She often takes midnight walks in the corridors accompanying a naked masochist Yuzuki, which usually makes her get carried away and shame and bully the masochistic Yuzuki. She actually hates Yuzuki and when Yuzuki shamed the protagonist and insulted her loved dick, that was the last straw. She swore loyalty protagonist, or at least his penis, ant told him about Yuzuki's naked routine.
