Hakata Tonkotsu Ramens

Contract killer Saito is forced into a low-level job in Hakata, a ward of Fukuoka, Japan; private detective Banba probes another detective's suspicious death, which points to the mayor.

Lin decides to protect Banba while he seeks revenge on his former employer, Zhang; Jirou and Misaki mistake Saito for someone else, with brutal consequences.

Jiro looks for the real killer to clear Saito's name; Lin receives devastating news that hardens his resolve to get back at Zhang.

Lin learns the identity of the one who killed his sister; Banba and Lin organise a trap for the enemy.

Banba takes time off to relax at the Yamagasa Festival; a skilled assassin moves to Hakata to find more challenging work.

Saruwatari decides to make the Niwaka Samurai his next target; with Banba away at the festival, Lin fills in for the Niwaka Samurai and ends up in over his head.
