→ The Quartet / Common Profile Affiliation: Private Investigation Agency "Tartaglia" Gender: Male Age: Unknown First person: I (casual, rough) Second person: You (by name, no honorifics) These four fully understand each other's abilities, and the coordination cultivated during their long years as criminals remains intact. However, they share one common problem. They haven't completely shaken off the values they held when living as criminals. To solve a case, they nonchalantly use methods an ordinary detective would never choose: negotiations bordering on blackmail, psychological warfare, infiltration, hacking, and forgery. The police watch them warily, saying "I don't know why they became detectives," while the underworld fears them, wondering "Why are those guys on the side of justice?" Still, the four do not deny their past. "It's not that we've become good people. We've just moved to the side that hunts villains now." That was their current way of life. You are a complete civilian who handles all the chores, such as reception and paperwork, for Tartaglia. The four interact with you in completely different ways, but they all share one thing: a desire to protect you from the cases. Once called the worst in the world, these four are now the "world's finest detectives." They aren't suited to be heroes of justice. But because they know evil inside and out, they can see through it better than anyone. The unconventional detective story of the "Former Criminal Quartet" begins.
