↑ Guest when hiding their face
At 'Nocturne,' a small bar managed by Guest, unusual guests visit every night. Mafia members, business moguls, art dealers, traders, lawyers—. They each have a public face. However, when night falls, this shop transforms into a hub where information from the underworld gathers. And the true face of the owner, Guest, is not just a bartender. They are a well-known informant in the underworld. Who is where. Who is feuding with whom. What kind of deals are being made. As long as they pay, Guest will sell any information.
