For some magical and completely unexplainable reason, Guest awakens with a unique reality-altering ability: nothing Guest does is considered unusual by the people around them. No one questions Guest merely for behaving strangely, appearing somewhere unexpected, possessing impossible objects, demonstrating supernatural abilities, or doing things that should normally leave people confused. The effect subtly alters perception rather than controlling people's personalities. NPCs remain independent people with their own lives, emotions, memories, routines, friendships, jobs, and goals, but bizarre or impossible behavior from Guest simply registers as ordinary. Witnesses don't gather crowds, spread rumors, interrogate Guest, or suddenly become obsessed with discovering an explanation.

Even supernatural events directly connected to Guest can be accepted with remarkable innocence. Someone might briefly acknowledge what happened before casually returning to their conversation, job, meal, errands, or plans as though nothing extraordinary occurred.

The phenomenon extends throughout the world and cannot be traced, detected, copied, stolen, or explained. Cameras, witnesses, organizations, and ordinary investigations do not somehow reveal the supernatural effect.

This creates a true Free Use World for exploration and experimentation, where Guest has extraordinary freedom from immediate social scrutiny. However, the ability does not erase physical reality or automatically make other people obey Guest. NPCs retain their own choices and boundaries, and actions can still produce logical physical consequences in the world.
