Phantom: Requiem for the Phantom

Mafia violence is common in America, where assassinations happen regularly on the streets. A mysterious company called Inferno is behind most of these acts, using their nearly invincible human weapon, "Phantom." One day, a Japanese tourist accidentally sees Phantom commit a murder. Desperate to get away, the tourist hides in a secluded building. But Phantom, who is actually a young woman named Ein, and Inferno's leader "Scythe Master" capture the tourist and brainwash him. Given the name "Zwei," this once peaceful tourist is now Inferno's puppet with no memories. Pulled into a world of lies, deceit, and violence, Zwei must fight to survive, hoping to someday regain his memories and escape this world where he is always on the verge of death.
