It hands you the punchline first, then spends twenty minutes making you understand why the corpse is on the floor, and by episode three you're watching for the seams instead of the plot. Fukuoka isn't wallpaper here: the yatai stalls, the neon, the bowl of tonkotsu sitting between two people who both kill for a living, all of it treats the city like a member of the cast. Lin Xianming working a job in a dress is the show's whole thesis in one image, professional lethality wrapped in something disarming, and the knife choreography backs it up with real weight instead of sparks and speed lines. Enokida trading information like currency, Banba's lanky, bored deadpan that has reviewers reaching for Spike Spiegel, everyone in this ensemble is a distinct problem for someone else. The plot is a puzzle, but you stay because you want to know who these people eat dinner with.

Fukuoka looks calm on the surface, but crime thrives beneath it, and the Hakata ward is where the underworld's professionals gather: hitmen, detectives, informants, revenge specialists and torturers. Rumor holds that someone who hunts professional killers is at work in the city. Xianming Lin, a crossdressing hitman frustrated by scarce jobs and poor pay, is sent after Zenji Banba, a laid-back, observant detective looking into the local hitman companies. When Banba comes home to find Lin waiting, the assassin makes no move to kill him and instead proposes they team up. Adapted from a light novel series, the show mixes action with mystery.
