Well, he was looting my lord's estate in the memory and now needs dead. I'm not sure if that means he's dead outside the memory or not. If he's dead... I guess it wasn't a memory and instead it was time travel.

confirmed: hes no longer at his peddling spot after killing him. Im starting over haha .

In memory his dialog is probably a hint to the location of mist raven tool.

When Anayama asks you for an employee to loot the battlefield for him. Someone strong and big. He is referring to Kotaro in Senpou Temple, Mt. Kongo. If you give him the Red and White pinwheel he can be sent to Anayama for more items.

Thought this guy was patches telling me to go to the top of hill to get an item...hmmm

I accidentally hit him how do I reset his agro I really need those scrap irons and black power

I'm not sure what triggered it, but he now sells divine confetti for 300 sen in infinite quantities. My game state is in night time so maybe that is related?

when The Central Forces initiated their full assault, if you sent Kotaro to Anayama, you will find them behind their usual place. There, you found Kotaro already died, leaving only Anayama. When you asked him he said, The Central Forces took everything he had, both of them resisted, they killed Kotaro and injured Anayama in the process. He then proceed to sell you one last item, "Promissory Note" which gives you discount on merchants. After that he succumbed to his injuries. If you didn't sent Kotaro, you will found Anayama dead in his usual place and you won't get the Promissory Note.

That entry is wrong about impossible to obtain Kunai. Near the end of the game it appears in the offering box for 4500
