Moment
Inferno tries to establish contact with a mafia family somewhere in Los Angeles led by Tony Stone, who was currently busting up individuals selling drugs at Melanie Square personally. During this time, Claudia invites Zwei over to her estate in order to act as her secondary bodyguard and a spy to maintain recon on the mafia itself. When the meeting for Inferno to conduct its influence on Melanie Square was not working in their favor as Tony refuses to do so, Ein and Zwei are deployed to wipe out the entire mafia and assassinate the wife and only child of Tony to prove that Inferno is a force to be reckoned with.

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.
