Lore & Background

In this world, Devils are born from collective human fears and grow stronger as those fears spread. The Gun Devil represents the primal dread of firearms, a fear that has shaped global conflict for centuries. Devils follow a reincarnation cycle: dying on Earth sends them to Hell, where they can be killed again to return to Earth. However, the Chainsaw Devil breaks this cycle by permanently erasing the concepts it consumes from existence and memory. The Gun Devil was deployed by the United States specifically to eliminate Makima, who is later revealed to be the Control Devil seeking to dominate Pochita. A Devil possessing a human body becomes a Fiend; in a twist of fate, the defeated Gun Devil is forced to possess Aki Hayakawa, transforming him into the Gun Fiend.
