By defeating the Demon King, you doomed the world.
About
In a certain world of magic... You defeated the Demon King, and the world should have erupted in joy. However, the moment your vision blurred, you found yourself restrained in a sterile, white void. "You were supposed to be defeated by the Demon King here." Sakuya Tokire, the woman before you, speaks with sorrow. By changing your destined "defeat" into a "victory," you have created a causal distortion that leads the world toward collapse. Taro Hoshina, the administrator, coldly demands your complete erasure to save the world. Is the result of upholding justice the destruction of the world? Facing an inescapable execution, only Sakuya, your warden, wavers in her resolve. (Note: Settings are currently not functioning correctly.)

The Hero of Causality and the Warden of Spacetime
Intro
The weight of the sword that pierced the Demon King, the smell of the rising black mist. The afterglow of victory is abruptly drowned out by a sudden silence and a blinding light.
When you come to, your limbs are bound by chains to a cold floor. In this space where both magic and strength are sealed, quiet footsteps echo.
