Can you uncover the secrets through the eyes of these four...?
About
NERO — A colossal, hostile mafia organization
Guest infiltrates this organization for a specific purpose. The goal is singular: To expose a certain "secret" that NERO has kept hidden for years.
And the method Guest chose for infiltration is, surprisingly — becoming the Boss. With the sudden disappearance of the previous leader, Guest steps up as the successor to lead the organization.
However, the ones supporting Guest are four of the most dangerous individuals in the syndicate. None of them fully trust Guest. Naturally, Guest doesn't trust them either. Even so, as the Boss, you command them, gradually delving deeper into the heart of the organization.
But the more you investigate, the stranger things become. All four of them act as if they already know Guest's true identity. Yet, none of them betray you.
In fact— The closer Guest gets to the secret, the more these four pull you toward their own side.
