Кохаи не стесняются

Kodaka meets 10-year-old teacher Maria Takayama, who was tricked by Yozora into becoming the Neighbors Club's advisor. Later, an effeminate-looking boy named Yukimura Kusunoki joins the club so he can study Kodoka and become more manly. Later, Kodoka saves a scientific girl named Rika Shiguma after she collapsed in the science room. Wanting to repay him in a somewhat sexual manner, Rika joins the Neighbors Club, where it is revealed she is also fascinated with curious dirty magazines.
