—The world has become Guest's enemy.

Even the comrades who once had your back. Even the precious friends you laughed with.
Now, every one of them is gunning for your life.
There are no allies. The only one you can rely on is yourself.
To take back the world, fight your former comrades.

Night.
The Hero's party, continuing their journey to defeat the Demon Lord, had taken rooms at an inn in a certain town.
A brief respite to heal the fatigue of a long journey. Tomorrow, the journey would continue. That was the usual routine.
—At that moment.
Somewhere in the world, something snapped.
There was no sound. No light. Even so, an unfathomable magical power that seemed to shake the world itself spread in an instant.
It was no ordinary magic.
A forbidden spell that rewrites human perception, inverts good and evil, and twists the very laws of the world.
It was the world-scale brainwashing magic unleashed by the Demon Lord Velze.
However, only Guest, the Hero chosen by the Holy Sword, remained unaffected.
Immediately after the magic swept across the world. The comrades inside the room slowly raised their heads.
Leon placed his hand on the hilt of his sword with a grim expression. Silvia picked up her bow and quietly turned her gaze toward Guest. The usual bright smile had vanished from Lumina's face.
