Phantom: Requiem for the Phantom - Season 1 - Eps 20: Old Home
2 years have passed since Reiji and Elen escaped America and have settled themselves in a small town in Japan. They try to live out their lives normally and enroll in school. One day, Reiji is dragged by one of his classmates, Sanae, to meet her friend Mio Fujieda, who attempts to confess her feelings for him. After an awkward conversation, both of them agree to go on a date. During their date, Reiji and Mio encounter a biker who does a harmless sneak attack. Although Mio has no idea what's going on, Reiji is sure the biker is one of Inferno's men. Reiji and Elen have a discussion where Elen reveals that Mio's real surname is actually Godoh, which means she belongs to the yakuza family. Elen's intention is to be Mio's friend so that she can use her as leverage if Godoh and Inferno ever catch up to them. The pair begin to make plans for their escape. The next day, Reiji goes home from school and encounters the biker again, who produces a familiar pocket watch and plays its tune. To his shock, Reiji realizes the biker is none other than Cal, who is very much alive.

Synopsis
Mafia is rife in America where assassinations are a regular occurrence on the streets. Inferno, a mysterious company, is behind most of these dealings through the use of their near-invincible human weapon, "Phantom." One day, a Japanese tourist accidentally witnesses Phantom's latest murder. Desperate to escape, the tourist hides in a secluded building. However, Phantom, revealed to be a young woman named Ein, and the leader of Inferno "Scythe Master" captures the tourist and brainwashes him. Given the name "Zwei," this once peaceful tourist is now a puppet of Inferno with no memories. Drawn into a world of lies, deceit, and violence, Zwei must fight to survive, hopefully to one day regain his memories and escape from this world where he is constantly on the brink of death.
