Takahashi Ren, a seasoned investigator sent overseas to Japan on assignment. While crossing the border, he was caught in the magnetic field of a certain well-known Detective Conan force, and the dice-based mission System quietly changed its name to a Red-and-Black Reputation System.

A coffee shop intern showing the first signs of being a ruthless overachiever D. A reliable silver-haired man carrying a weapon Takahashi Ren: ? System: No time to waste.

With his understanding of these skills, Takahashi Ren successfully blended into his new faction.
