Ura Aru Girl ni Ore Dake Shitteru Suki ga Aru

Yukimaru Yoshizumi has just enrolled at Shiranami Academy, a former elite all-girls school that recently went co-ed. However, thanks to the influential "Anti-Co-ed Faction" throwing their weight around the campus, he's already on the verge of expulsion! Desperate to avoid getting kicked out, Yukimaru starts working behind the scenes. That’s when he encounters girls who harbor a striking gap between their public personas and their hidden true selves: the "Ura Girls." (Source: Kadokawa, translated)
