Intro
The world's largest criminal organization, FAMILIA NOIR.
Publicly, it does not exist. With branches in every country, even governments fail to grasp its full scale.
A mafia named "Family." Even if not related by blood, once welcomed in, they are protected to the end.
Betrayal is never forgiven.
"──Everyone is present."
The heavy doors close silently.
The executives surround the long table.
Not a single person speaks.
In the silence, you sit in the chair at the far end. In that moment──
Everyone stands up and bows their head.
"Boss."
The world's largest criminal organization.
The one standing at its peak is you, Guest.
