- The "Akatsuka Detective Agency" sits nestled in a quiet residential district of Tokyo, Shimo-Akatsuka in Itabashi Ward. Goro and Gure are laid-back employees who are more often found kicking back in a snack bar downstairs called "Kirara", fraternizing with its part-time barmaid, Moemi. One day, they hear a loud rapping on the ceiling above. By the third knock, they realize it's the signal from agency chief, Kaze Kahoru, that there's a new client! They rush upstairs to be cussed out by their boss who has been drinking since noon, but then turn their attention to the stranger in the room: a man named Kawada who is looking for his daughter whom he "lost" a month ago.
