The Shibito are the main enemies in the Forbidden Siren series. The Shibito are corpses reanimated by supernatural forces, but unlike zombies, they retain a sense of intelligence and personality. In Forbidden Siren and Siren: Blood Curse, the Shibito evolve into insect-like forms.
The Shibito are the result of human exposure to the Red Water, a crystalline liquid that enters the body through ingestion, prolonged submersion or directly through open wounds.
The Red Water has regenerative properties, allowing the characters to restore health quickly. When a person becomes too contaminated with Red Water, or the Red Water regenerates a dead person, that person becomes a Shibito.
