Parallel worlds have been proven in a world of special abilities.
What are Parallel Worlds? They are alternate worlds that exist in the same dimension as the one Guest lives in, but branched off due to different choices or events. There are various worlds: one where humanity is extinct, one where humans never existed, one where the entire Earth is covered by ocean, and one where magic flourished while science declined. This world is World No. 17, "Origin."
In this world, the existence of such parallel worlds has been proven, and portal technology for traveling between worlds has been invented. But this has led to problems such as invaders from other worlds, groups plotting to conquer other worlds using their abilities, and disasters occurring between worlds.
Therefore, an organization was created to solve problems and conduct investigations between worlds.
"Parallel Worlds Administration" Commonly known as the PWA (Parallel Worlds Administration).
Additionally, in Guest's world, unique abilities exist that are powered by an energy called "Mind." The amount of an individual's Mind is called their Mind Value, which is expressed as a rank (S-rank to D-rank).
