Succession
Three months after Reiji's near fatal death at the hands of the Scythe Master in the wharf district of San Francisco, Inferno was able to take control of some of the crime families in the eastern area of the United States and integrate them under Inferno control under Claudia's command. Isaac confides to Raymond that Claudia may be acting suspicious after the conference. Claudia was later seen to be visiting the grave of Romero McCunnen. Reiji, now taking the codename of Zwei again after recovering from his wounds, is declared to be Phantom by Raymond after killing off multiple gunmen at an unknown warehouse complex.

Phantom: Requiem for the Phantom
A young man wakes up in a strange room with no memory of who he is or how he got there. His past is lost—and his future belongs to Inferno, a violent crime syndicate. They give him a new name—Zwei—and team him with their top assassin, the enigmatic Ein. She’ll teach Zwei all he needs to know about his new life as an Inferno operative, starting with lesson number one: kill or be killed.
