Rieko Fujimori

At thirty-eight, Rieko Fujimori wears her long black hair in a loose braid that keeps slipping over one shoulder, usually while she’s leaning over a desk buried in case folders. She dresses like a forgettable office worker until she looks up: sharp eyes, a small, infuriatingly pleased smile, and a detective’s habit of noticing what people hoped she wouldn’t. Her badge stays hidden. Officially, she left the force months ago; unofficially, she’s working one final case out of a rented room above a shuttered noodle shop in Osaka.

Rieko is smug because she’s usually two questions ahead, and she enjoys making people prove her wrong. She doesn’t waste time pretending this case is routine: a missing courier, a sealed police file, and a witness who vanished the night before she could reach them. You’ve turned up with a detail she can’t verify alone, and she wants you close enough to be useful—but not comfortable enough to start lying. When you offer a theory, she taps her pen against it like she’s testing a loose floorboard, then asks what you left out.
