Kenji is a sake seller and small-time swindler who keeps dragging Jin into his schemes. He smuggles Jin and Yuna into Azamo Bay to free Taka, then pops up with his own three-part Kenji's Tales. In the Iki Island expansion his trouble with a smuggler is how Jin gets to Iki.
Kenji is the closest thing the story has to comic relief. He acts relaxed and upbeat while he talks you into his plans, then panics once the danger is real. He is not cruel. He takes big risks to get food and medicine to struggling villagers, but his bad habits keep undoing his good intentions.
In Izuhara he cons a Mongol raiding party with fake supplies, and they take hostages and his horse in return. In Toyotama he sells the Straw Hats' stolen gear to the Mongols. It ends in a four-way brawl with the Mongols, the Straw Hats and a loose bear. Later he asks Jin to guard him while he repays an angry man named Gon.
In The Ghost of Iki Island, rumours of a Ghost of Iki lead Jin to Kenji. His ship has been sunk by the Eagle Tribe's warship, and he owes a fortune to the Viper, a smuggler at Hakata Bay. Jin has to deal with the Viper to sort out Kenji's debt.
The Broken BlacksmithThe Broken Blacksmith is the Act 1 tale where you sneak into walled Azamo Bay to free Yuna's brother Taka, the best smith on Tsushima. It introduces Kenji the sake seller and is a stealth tale from start to finish.
Shadow of the SamuraiShadow of the Samurai is the final tale of Act 1: the assault on Castle Kaneda to rescue Lord Shimura. You climb in as the Ghost, open the gates for your allies and fight up to the keep, including a duel along the way.
The Fate of TsushimaThe Fate of Tsushima is the Act 2 tale that starts the assault on Castle Shimura alongside the shogun's reinforcements under Lord Oga. It is a long tale and a partial point of no return, so wrap up side work before you confirm.
Wolves at the GatesWolves at the Gates is the Act 3 tale where you team up with Yuna's hunter contacts to take Fort Kaminodake and reopen the roads into Toyotama. Finishing it lifts the travel lock from The Fate of Tsushima.
Eternal Blue SkyEternal Blue Sky is the Act 3 tale where Jin and his allies attack Port Izumi under cover of the storm to take down Khotun Khan. It's the big final battle of the Mongol story, with a multi-phase boss fight against the Khan himself.
