Sakura, the only human in a class full of monster girls, dives headfirst into interspecies sapphic school life! Now at Satomigaoka’s seaside school for a hands-on summer learning camp, Sakura meets a slime girl, Komari, who molds herself to Sakura’s likeness! Then, Sakura gets into an accident with Mai, a scylla who has something against succubi, and gets ensnared in a boob-a-licious swimsuit jostle…! But can Sakura keep her cover story intact even if she loses her top?!
