Phantom: Requiem for the Phantom - S01

The American underworld is ruled by ruthless mafia factions, where assassinations are an everyday reality. Most of these killings are orchestrated by a shadowy organization called Inferno, which employs a nearly unstoppable assassin known only as "Phantom." One day, a Japanese tourist accidentally sees Phantom commit a murder. Fleeing for his life, he takes refuge in an abandoned building-only to be captured by Phantom herself, a young woman named Ein, and Inferno's leader, "Scythe Master." Brainwashed and stripped of his past, the tourist is reborn as "Zwei," a soulless weapon under Inferno's control. Thrust into a world of deception and bloodshed, Zwei struggles to survive, clinging to the faint hope of recovering his memories and escaping the deadly cycle that could claim his life at any moment.
