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.
Ryuzo wants to lead, not follow, and he cares more about feeding his men than about honour. He admires Jin and resents him at the same time, ever since Jin beat him with real ferocity at the tournament. He is realistic about his own skill and admits Jin is the better swordsman.
Jin finds him hunting near Kishi Grasslands in Blood on the Grass. Ryuzo will help rescue Shimura, but first Jin must help his starving men hit Fort Ohira for supplies. In The Tale of Ryuzo and The Iron Hook they follow a supply map and free captured Straw Hats near Fort Yatate.
The Mongols fed his captured men well, and Ryuzo sells out to them. During the assault on Castle Kaneda he turns on Jin, loses a duel and runs. The Khan then makes him burn a peasant alive outside Castle Shimura, which breaks him. He later sets the trap at Fort Koyasan that leads to Taka's death.
Jin finds him in Castle Shimura's keep after the poisoning. Ryuzo asks Jin to say he was a spy all along, but Jin will not forgive Taka's death. They duel a final time and Jin kills him with his tanto, ending the Straw Hats.
Blood on the GrassBlood on the Grass is the Act 1 tale where Jin looks for the Straw Hat Ronin and reunites with his childhood friend Ryuzo. It rewards the Ronin Attire and leads straight into The Tale of Ryuzo.
The Tale of RyuzoThe Tale of Ryuzo is the Act 1 tale where Jin helps Ryuzo's Straw Hats find food, starting with a raid on Fort Ohira and ending on Mongol ships offshore. Finishing it secures the Straw Hats for the rescue of Lord Shimura.
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.
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.
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.
From the DarknessFrom the Darkness is the last tale of Act 2, where Jin goes against his uncle's orders and sneaks into Castle Shimura to poison the Mongols. It gives you the Ghost Armor and ends with the story moving north to Kamiagata.
