Taka is Yuna's younger brother and a gifted blacksmith. Jin and Yuna rescue him from Azamo Bay, and he forges the grappling hook that gets Jin into Castle Kaneda. He is gentle and not much of a fighter, but he wants badly to help the Ghost.
Taka is kind, quiet and a little naive. Yuna has protected him all his life, from their violent mother and later from the slavers who bought them. He knows the old passage into Yarikawa from childhood and uses it to sneak Jin into the besieged stronghold.
In The Broken Blacksmith you break into Azamo Bay, where a Mongol slaver means to kill him. In The Iron Hook and Hammer and Forge he works on the grappling hook. He then joins Jin and Yuna at Yarikawa, where he insists on coming along to find the archers, and helps fight off Temuge's siege.
Taka leaves Yuna a note and follows Jin to Fort Koyasan to act as a distraction. He is captured. Khotun Khan hands him a sword and tells him to kill Jin. Taka swings at the Khan instead and is beheaded. Jin and Yuna bury him with his headband on the grave.
Yuna later gives Jin the Ghost Armor Taka was making for him. Jin wears it to poison the Mongols in Castle Shimura. His death drives both of them to finish the Khan and the Straw Hats who betrayed them.
The Warrior's CodeThe Warrior's Code is the first tale of Act 1, where Jin and Yuna raid a Mongol prison camp looking for her brother Taka. It is the stealth tutorial: you learn Assassination and Focused Hearing and get the Sakai Tanto.
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.
Hammer and ForgeHammer and Forge is the Act 1 tale where you retake Komatsu Forge so Taka can build a tool to climb Castle Kaneda. You rescue his assistant Yukio and the town's hostages, then defend the forge against a Mongol warlord.
The Iron HookThe Iron Hook is the Act 1 tale where Taka finishes your grappling hook and you test it on Fort Yatate while freeing captured Straw Hats. It is the tale that unlocks the Grapple hook for climbing.
The Walls of YarikawaThe Walls of Yarikawa is the first of three Act 2 tales about winning over Clan Yarikawa. With Yuna and Taka you sneak past the Mongol siege camp through a secret entrance under a waterfall to reach the stronghold's steward.
The Coward of YarikawaThe Coward of Yarikawa is the Act 2 tale where you search the ruins for Yarikawa's missing archers to prove yourself to the steward. It ends with an explosive ambush on a Mongol convoy that thins out the siege force.
The Ghost of YarikawaThe Ghost of Yarikawa is the Act 2 tale where the Mongols storm Yarikawa Stronghold and you lead its defense against General Temuge. Beating him unlocks the Ghost Stance, one of Jin's strongest techniques.
A Reckoning in BloodA Reckoning in Blood is the Act 2 tale where Jin raids Fort Koyasan to settle things with Ryuzo before the attack on Castle Shimura. It is one of the darkest tales in the story, so finish any prep you want first.

Ryuzo
Ryuzo is Jin's childhood friend and the leader of the Straw Hat ronin. After the Mongols nearly wipe out his men, he joins Jin to raid for food and help free Lord Shimura. His friendship with Jin is the heart of The Tale of Ryuzo and several main story tales.
Temuge
