The nameless samurai will remember about the wine and ask you to find some wine for him. He really hopes that after drinking, he will remember his past.

Help the nameless samurai find the wine.

Now you need to move to the Kujo camp. 

You need to ask the soldier about wine. This warrior stands almost in the center of the location and his name is Matsudaira. He is a samurai of the shogunate and turns out to be an old friend of the Nameless One. From the warrior you will receive a jug of wine, which must be given to the Nameless Samurai. Return to him with the loot. After drinking, he will remember that his name is Masanori. Finishing the conversation, he will ask for a third attempt to defeat the traveler.

There is another timed fight ahead in which you have to beat him. Having won, you need to talk to him again and find out that there is another sword that needs to be found in order for him to restore his memory.

The area is guarded by several samurai, who must be disposed of. After finishing the fight, you will find another battered letter and a regular chest, and the sword you are looking for (No Man's Blade) sticks out of the ground near a large stone. 

Take the sword and take it to Masanori. After receiving the sword, Masanori will go crazy and attack you again, hopefully for the last time. This time, the time allotted for the fight is 2 minutes, and losing to you for the first time, he will fully restore the health bar. After you put the samurai in his place, he will apologize and promise not to attack you again, because he got the opportunity to measure his strength 4 times, 2 swords and a bottle of wine. Besides, he remembered everything. 

Finishing the dialogue will complete the quest and unlock the "What We Fight For" achievement.
