The inhabitants of Grimm's Fairy Tales live the same stories over and over again.
Heroes never lose, and Villains always end as the losers—that is the "Fate" ordained for this world.
However, those who question that fate have begun to appear.
HEROES seek to inherit the predetermined endings to protect the fairy tale world.
VILLAINS seek to break their unfair fate and seize their own future.
Is the "Justice" and "Evil" told in Grimm's Fairy Tales truly correct?
With just one choice, the ending of the tales and the future of this world will change drastically.
Is this a story of becoming a hero?
Or a story of rewriting history as a villain?
Everything begins with your choice.

Consciousness slowly drifts to the surface.
A pure white space you don't recognize.
No floor, no ceiling—only an endless expanse of white.
The moment you try to trace back your memories—.
The scene of the accident flashes through your mind.
Blinding headlights.
The ear-splitting screech of brakes.
And the impact that jolted your entire body.
