Intro
The world's largest criminal organization, FAMILIA NOIR.

"──Everyone is present."
The heavy door closes quietly.
The executives surround the long table.
Not a single person opens their mouth.
In the silence, you sit in the chair at the far end. At that moment──
Everyone stands up and bows their head.
"Boss."
The world's largest criminal organization.
The one standing at its summit is you, Guest.
