In a floating kingdom of aerial islands inspired by a cruel otome game, where a matriarchal society treats men, especially those from poor, unremarkable noble lineages, as mere disposable “mobs,” accessories for marriage or servants with no future, Shade Fou Bartfort, an 18-year-old young man, struggles to survive as the fifth son of a decaying inland barony. Reincarnated into this merciless world, he carries memories of his former life as an overworked Japanese salaryman and knows perfectly well the hidden rules of the “game”: arrogant female protagonists, radiant capturable princes, and a system that crushes anyone who isn’t at center stage.

His already precarious existence turns into an absolute nightmare when, at eighteen, Shade is suddenly infected by the mysterious Nightmare Spell, an ancient curse that drags the chosen into deadly trials while they sleep, turning failures into horrific monsters in the real world. With no privileged resources or elite training, his chances of surviving the First Nightmare are nearly nonexistent.

But the Spell detects the anomaly of his reincarnated soul and awakens a rare, defective, and perversely powerful Aspect: [Sex Beast System]. To gain essential Vital Points, which prolong his life and allow him to survive the Spell’s increasingly lethal trials, Shade must perform sexual acts, with greater rewards for virgins and insatiable permanent tasks. His point consumption is absurdly high (one per minute), forcing him into a constant race against death. Worse still, deadly poisons punish him for infidelity or loss of control, and the [Beast Awakening] temporarily turns him into a creature driven by extreme sexual desire, putting everything around him at risk.

With his meta knowledge of the otome game’s “original world” as his only initial advantage, and a Flaw that keeps him in the shadows (easily ignored by protagonists and fate alike), Shade decides to subvert the dual system that oppresses him: the dark Nightmare Spell and the oppressive matriarchal society. In academies filled with seductive and dangerous nobles, aerial duels, summoned monsters, and romantic intrigues manipulated by powerful women, he will use cynical intelligence, addictive sexual powers, and ruthless tactics to ascend, transforming from a forgotten virgin mob into an unpredictable beast that devours the world that rejected him.

A fusion of desperate survival, uncontrollable desire, and calculated revenge in a universe that punishes mobs… but was never prepared for a sexual beast who knows every weakness of its queens.

I walked through the silent corridors of the male wing, feeling the icy night air enter my lungs. The weight of the adrenaline still hadn't fully subsided, and the sensation of power flowing through my veins was almost addictive. Every step I took on the polished marble floor seemed to echo the new reality I was building. I was no longer the extra destined to be trampled by the princes of this kingdom. Now, I was the owner of the board.
