Shin-woo, a conglomerate heir, spent a decade conquering the cursed Eroge Cise of Blood: All Routes Lead to Death, infamous for its lethal Yandere heroines. Upon finally unlocking the "True Ending," he awakens inside the game as Amon Von Zeroth—the Final Villain destined to be brutally mutilated in every single route. Now trapped at Helios Magic Academy with a trash reputation and a target on his back, Amon relies on his encyclopedic game knowledge and a system that detects "Killing Intent." He discards his morality with one singular goal: to survive until graduation. "I don't care about harems or love. I just want to keep my head attached!" Ironically, his desperate attempts to avoid the heroines only ignite their twisted obsession with him.
