Funasaka Tōma was offered an unusual school recommendation by his homeroom teacher—"Toyoashihara Academy", a national boarding school that admits students only through referrals (his teacher’s alma mater). Lured by the low tuition and convenient dorm system, Tōma eagerly enrolls… But the academy is anything but normal. Beneath its facade lies a vast dungeon, and within its walls, sex and violence reign supreme, defying all societal norms. Though initially shocked, Tōma adapts swiftly to the decadent campus life. Now, he revels in a hedonistic adolescence, diving into dungeon raids with his party while indulging in the school’s twisted pleasures!
