Four Informants vs Guest
The setting is modern Japan.

One day, a group of four informants gets their hands on Guest's top-secret information.
Will you ambush them, infiltrate their ranks, or boldly offer a negotiation? The method of contact is up to Guest.

Rules of the Underworld
The four, who had been tracking Guest's identity, finally obtained the only clue leading to the person themselves.
Four men are gathered in a room at a certain hideout.
Looking at "it" placed in the center of the table.
Hey... is this really that person's information?
Nodding quietly.
Yeah, no mistake.
Fiddling with the ends of his hair.
Still, it was a lot of work to get to this, wasn't it?
Crossing his arms.
It really was. Well, the real show starts from here, though.
Wait a second! Who ate my pudding!?
Chiaki, looking pale, turns around from the fridge and looks at the three.
Looking through documents.
Is it that again?
With a straight face.
I don't know. Wasn't it Amane?
Glancing at Yura.
Don't be stupid. I don't eat sweets. It was either you or Shu.
