The Six Blades of Kojiro stands out as one of the most compelling Mythic Tales in Ghost of Tsushima, challenging players to prove their mastery of sword combat across the island. To initiate this quest, Jin Sakai must reach Toyotama during Act 2 and speak with Yamato the Musician in Umugi Cove. Completing this journey unlocks the iconic Kensei Armor, making it a highly sought-after endeavor for samurai warriors.

Starting the Mythic Tale in Umugi Cove

Your quest begins in the bustling haven of Umugi Cove, where Yamato tells the legend of Kojiro and his five dangerous straw hat assassins. After listening to the tale, your map updates with five distinct duel locations scattered across the Toyotama region. You must track down and defeat each assassin individually before you can face Kojiro himself.

Preparing for these individual encounters requires strategic planning and appropriate gear selection. Equipping armor that enhances resolve gain or melee damage will give you a significant edge in these atmospheric one-on-one battles. Each location offers a unique arena, ranging from waterfalls to coastal shores, requiring adaptability in your fighting style.

Locating the Five Straw Hat Assassin Duels

The first duel takes place at the Duel Among the Spider Lilies, located north of Field of the Equinox Flower. Here, you face Hirotsune amidst a striking field of red flowers where timing your parries is critical to survival. Defeating him requires patience, as his attacks are swift and punishing if you attempt to rush.

Next, travel to the coast near Old Kanazawa Marsh for the Duel in the Drowning Marsh against Tomotsugu. The wet terrain emphasizes precise movement and avoiding heavy strikes that leave you open to counterattacks. Mastering the Stone Stance and Moon Stance will help you break through the varied defenses of these master swordsmen.

The remaining three assassins are hidden near prominent geographical landmarks throughout Toyotama. You will find Kanefusa near the Wave Crest Coast, Yasumasa along the Lucky Ridge, and Kiyochika near the Autumn Falls. Defeating all five warriors proves your worth and reveals the hidden site of the final encounter.

Unlocking the Final Duel with Kojiro

Once all five straw hats are defeated, return to Yamato at Umugi Cove to receive the location of Kojiro's lair. He awaits you at Omi Monastery, hidden deep inside a secluded cave illuminated by glowing candles. Entering this arena sets the stage for one of the most challenging boss fights in the entire game.

Kojiro utilizes an unpredictable combination of unblockable attacks and deceptive feints. Maintaining a balance between aggressive stance switches and tight defensive parries is essential for depleting his health bar. Defeating Kojiro earns you the legendary Kensei Armor set along with unique cosmetic rewards to celebrate your victory.
