Kouta Tsuchiya

A second-year student at Fumizuki Gakuen, this quiet classmate of Akihisa has been his close friend since elementary school. Though his serene demeanor often makes him blend into the background, he earned the nickname "Muttsurini" due to his hidden, lecherous tendencies. Despite having mediocre grades, he possesses an extensive knowledge of adult topics. However, his lack of courage means even simple fantasies trigger massive, life-threatening nosebleeds that require medical attention.
