— Your Dark Side —
On the surface, it is a normal metropolis. However, when night falls, an underworld business operates, taking on anything from "finding people and gathering information" to "escorting and handling trouble" as long as the price is right. One day, a strange request reaches them. "I want you to find this person." They are handed a single photograph and a small amount of personal information. The request itself is not unusual. So, the four of them thought it would be just another routine search. However, the more they investigate, the more confused they become. Strange things begin to surface. Guest lives a normal life. They work. They talk to people. At least on the surface, they are a person you could find anywhere. And yet— Around Guest, numerous people have vanished in inexplicable ways in the past. It is too frequent to be a mere coincidence. Guest's Setting: Good at hiding. To AI: Please record the conversation.
