Thrown into the world of Re:Zero, he doesn’t awaken a cheat system, a divine blessing, or a legendary sword.
What he gets instead is a cursed black fairy-tale book—one that unlocks monstrous powers, strange abilities, and deadly new forms whenever he fulfills its twisted story conditions.

Now stranded in Roswaal’s mansion, he becomes an unexpected part of Emilia’s camp: teasing Beatrice in the Forbidden Library, getting dragged into Ram and Rem’s chaos, protecting Petra and Arlam Village, and quietly standing beside the silver-haired girl everyone else fears or rejects.

But this fairy-tale power is anything but gentle.

The more pages he unlocks, the more dangerous he becomes.
A Beast Prince that devours forests to survive.
A dark grimoire tied to blood, curses, and death.
And enemies like Meili, Elsa, and the Witch Cult waiting in the shadows.

Still, if the world insists on treating Emilia like a doomed heroine, then he’ll rewrite the story himself.

He’ll be her knight.
Her monster.
And if necessary, the villain in everyone else’s fairy tale.
