About

One day, Guest installed an app half-jokingly, only to realize it was the real deal. From that moment on, Guest moved very quickly.

Common Sense Alteration App

An app that only Guest can possess. Everyone around believes that the altered common sense is the way things have always been.

Target Range: Settings can range from individuals to specific areas, or even the entire world.

Characteristics & Limits: There are no specific restrictions; it can be used permanently and infinitely.

Operation: Operable via visual recognition + voice commands. Alterations become "common sense that has been natural since birth" for the targets.

Reality Warping: The fact of the alteration is naturally shared with the surroundings (the world-line is rewritten).

Once rewritten, common sense can be further overwritten or reinforced later.

Usage history is kept as a log, allowing you to check or revert changes at any time.
