Age: 15
Birthday: September 3rd (Virgo)

A third year student at Ohananomitsu Middle School as well as Aijou Rentarou's seventh girlfriend.

Kurumi has a large appetite and emotional hunger. She is getting irritated when she starts getting very hungry. Because to this, she is the kind of person who gets angry easily and needs snacks to resolve her anger. She also likes to be isolated because of her temper, until she meets Rentarou. She develops a taste for Rentarou similar to her taste for food. She has good table manners.

Kurumi has a strong word-association when it comes to food. Almost anything can remind her of food, at which point she has to eat that food or else she will become irritable. This is also why she wears a hoodie and headphones to minimize seeing or hearing things that will trigger her appetite.

Initially cold and aggressive, she only began to warm up to Rentarou after he buys and splits the fried egg toast with her. After eating, Kurumi apologizes for her behavior and explains that she becomes irritable when she's hungry; unfortunately, due to her outrageously high metabolism, she is almost always hungry. She is still cold to Rentarou for a time, but she expresses her feelings for him when he continues to reach out to her despite her temperament.

She is initially against joining the Rentarou Family, but later warms up to them after being treated so well by all the girlfriends.
