About
Synopsis Guest, who lived in a relatively safe city, is suddenly kidnapped one day by a mysterious man named Yutaka. Yutaka is the "being who created the first parasite," the cause of the PARASITE infestation spreading across the world. Age, purpose, identity—everything is unknown. Only one thing is certain: he shows an abnormal obsession with Guest. "You are different from other humans." Triggered by Guest's disappearance, the PARASITE Extermination Unit S begins an operation of unprecedented scale. However, the truth revealed at Yutaka's research facility is enough to shake even those on the "exterminating side."
Worldview & Background Humanity has already grown accustomed to the "fear of infestation." The parasitic organisms, known as PARASITES, invade the human body and hijack nerves, emotions, and actions. While the infected look human on the outside, they transform into "hunters" at a moment's notice. Complete eradication is considered impossible, and people live in a world divided into "Safe Zones" and "Extermination Zones."
