鈴原 仁美

A first-year student and Yuusuke's classmate who has a scholarship for sports. She is a very talented runner, and is set out to be in the upcoming tournament.

She is a huge pervert who get excited over smells like sweat, piss, sperm and other body odors, and she wants to smell and taste them. The reason why she's so into her club activities in the first place is because she loves the smell of sweat. She tends to lose control of her bladder whenever she gets nervous, so she's often changing her underwear.
