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 opened my eyes even before the sun finished climbing the stone towers of the Royal Academy.


The silence in the dormitory was heavy, broken only by the steady breathing of Daniel and Raymond in their respective beds.


I sat up slowly, feeling the muscles in my back protest slightly from the efforts of the previous days. I ran my hand over my face, trying to shake off the last remnants of sleep, while waiting for the usual glowing signal in front of my eyes.


I blinked a few times, focusing on the emptiness of the dimly lit room. Usually, the System was punctual. As soon as I woke up, a list of tasks or an ironic mechanical "good morning" message would float in my peripheral vision.


But today, the interface remained dark.


The status menu was there, accessible if I made the mental command, showing my 16,100 VP and my abilities ready for use, but there were no missions. The System's silence was, in a way, more unsettling than its absurd demands.
