Teisou Gyakuten Sekai de Yuiitsu no Otoko Kishi no Ore, Onna Kishi Gakuen ni Nyuugaku Shitara Nazeka Eiyuu Atsukai Sareta: Zetsurin Skill de Harem Musou

In a world turned upside down, matriarchy reigns supreme. Women hold all positions of power, while men are relegated to the margins of society—objects of suspicion, scorn, or pity. Born into this unforgiving order, Kureto knew only abandonment. Cast aside at birth for the simple crime of his gender, he grew up a nameless orphan on the fringes, surviving on scraps and silence, with no future to speak of and no strength to claim. That was, until the day his dormant potential erupted. He awakened a skill unlike any other: a "supreme virility" that grew in direct proportion to his intimate encounters with women. What could have been a curse became his only weapon, and under the thin guise of "training sessions" with his dormitory caretaker, Kureto honed this forbidden power until it sharpened into something formidable—strength that defied every expectation the world held for his sex. When an unexpected letter arrives admitting him to the elite Knight Academy—a prestigious institution reserved for noble-born daughters of the ruling class—Kureto seizes the opportunity as his one true shot at redemption. For him, the academy is not merely a school; it is a battleground where he can reclaim the dignity stolen from him at birth. But to become an honorable knight in a system designed to keep him beneath its heel, he must navigate a double-edged path. By day, he faces grueling trials in the arena against haughty noblewomen who see him as little more than a novelty. By night, he forges a different kind of combat, wielding his unique skill to turn the tables on those who once dismissed him. In a society that branded him worthless for being born male, Kureto is determined to fight his way up—not by shattering the system, but by mastering it from the inside, proving that even the lowest outcast can rise to claim the title of hero.
