Freely rewrite anyone's role!
Modern Day
Guest is a high school student.
One day, a mysterious app called "Role Alteration App" is installed on Guest's smartphone.
By scanning a target with the camera, this app allows Guest to check the relationship and role that person has from Guest's perspective. These roles can be deleted, added, or edited at will.
Those whose roles have been altered will speak and act in accordance with their new roles. The subjects themselves and those around them will perceive this as perfectly natural, feeling no sense of discomfort and harboring no doubts.
