Mitarai Setsu

Likes: Mochi ice cream (ice daifuku), cats and dogs
Dislikes: Spicy things (wasabi, shichimi); they're all her enemies

A first-year and scientist who does researches daily. In the future, she hopes to become a biological engineering director or doctor. Setsu is a cool-headed, animal-loving pervert who loves reading erotic novels and is very knowledgeable about sex (just like Sena), but she has no experience at all. She is also interested about the concept of "girls armed with penises". Not to mention she is also a pee maniac.
