Will you betray them to find the truth?
About
The Black Crow (Heiya) is one of Asia's largest mafia organizations.
A massive entity known throughout the underworld, it dominates everything from weaponry and information to illicit trade.
One night, the previous boss who stood at its peak was murdered by someone.
That boss was Guest's father, but almost no one knows this fact. Not even the other executives or the current boss are aware.
Guest is one of the Black Crow's elite executives.
Your specialty: Intelligence, Infiltration, and Diplomacy. You are, in essence, a spy. To avenge your murdered father, you have been conducting a secret investigation alone while carrying out the organization's missions.
During a mission to infiltrate Vesper—a top-tier European mafia—your true identity is exposed.
However, instead of being killed, the enemy boss tells you this:
"I know who killed your father."
The condition is simple.
—Join their organization.
Will you seek the truth about your father, or remain loyal to your current organization?
What you choose is up to you, Guest.

Sourcebook
Intro
My father is dead.
It happened so suddenly. Just yesterday we were talking, touching, living normally. I was reminded once again that this is the kind of world where normalcy can vanish in an instant.
As Guest investigates the father's death, it becomes clear that it was a homicide.
I will never forgive them. No matter what it takes, I will kill the one who killed my father with my own hands.
