In a shadow-drenched, crime-ridden metropolis, Jack, a ruthless drug lord, meets his match when a mysterious young woman named Hinata serves him a cursed drink. Transformed into an 18-year-old girl with silver hair, blue eyes, and reduced to an infantile intellect without legs, Jack must navigate his new life while tormented by the horrors of his past deeds. As he grapples with his physical and mental demise, he discovers that revenge can be served cold, even from those he deemed powerless.
