A Reckoning in Blood Ghost of Tsushima Tale

1. Speak with Lord Shimura

Go to Lord Shimura's Camp and talk to your uncle. He will inform you of a new problem that has arisen. Ryuzo's men are preparing to attack from behind as you march to retake Castle Shimura. According to the information your uncle managed to intercept, Ryuzo should now be in Fort Koyasan. Before you go there, you decide to ask Yuna to help you for the last time.

2. Find Yuna / Speak with Yuna

Yuna and Taka are in the camp too. Unfortunately, Yuna, who waited so long to be able to get to the mainland, won't want to go with you.

3. Leave Lord Shimura'a war camp / Travel to Fort Koyasan / Survey Fort Koyasan

Head to the Fort Koyasan, get to the hill from where you can survey the fort and and start watching the fort. You will notice that in addition to Straw Hats, there are also a lot of Mongols in the fort.

Your observation will be interrupted by the arrival of Taka, who wants to help you at all costs. He'll come up with the idea that he'll lure the Mongols out of the fort and make it easier for you to get inside.

4. Enter Fort Koyasan / Make your way to the upper gate

Taka will get on his horse and shout some insulting words to the Mongols, which will make them angry and they will start chasing him. Once they leave the fort, you will be able to get inside through the main gate.

You must now reach the gate leading to the inner courtyard. The Mongols who remain in the fort and who stand in your way can be avoided and / or eliminated in any way that suits you.

5. Search for Ryuzo in the inner courtyard

When you open the gate to the inner courtyard, you will meet Ryuzo on the other side. After a short conversation with him, it'll turn out to be an ambush and you'll be captured.

When you regain consciousness you will see that apart from you, Taka was also captured. When you try to free yourself, Khotun Khan himself will come to you.

He'll try to convince you to persuade your people to surrender. He will decide to use Taka for his purpose and test his loyalty to you. Unfortunately this will end in the death of your friend. Khan will then leave you alone that you can think about what just happened.

6. Recover Gear / Recover your weapons

When you're alone, free yourself from the ties and then get your gear back, which you'll find in a box standing nearby.

7. Defeat all the Straw Hats / Escape from the inner courtyard

Then head your steps towards the gate and kill any Straw Hats that stand in your way.

When you reach the gate, you will meet Yuna there who saw Khotun Khan and Ryuzo leaving the fort and came here to look for her brother. You'll let her know that something terrible has happened.

8. Follow Yuna / Defeat all enemies

Yuna will run to where her brother's corpse lies. Follow her.

After a while, you will hear that more enemies are coming. Together you will have to kill about a dozen or so more and more powerful enemies coming in waves. They will be both Straw Hats and the Mongols.

When you get rid of all of them, you will take Taka's body and bury it. Yuna will decide to stay on the island and help you in your fight, and then this tale will be over.
