In new game plus, if you already had a promissory note from previous playthroughs, you can buy a dragons blood droplet from anayama after ashima outskirts is under attack. But, instead of adding a dragons blood droplet to your inventory you get a divine grass instead. This is assuming you followed anayamas quest and sent kotaru to him.
this guy is definitely patches: his vest is full of patches he has an eye patch used to be a thief, now a merchant tell you about the pagoda with a very tough early game enemy there that will wreck you trolls you at the end with a promissory note that he stuffed near his nutsack which still smells "fresh" he died and had the last lough and even got a sen for it
This dude was definitely my favorite npc in the game. I dunno I've always liked the "humble merchant" kind of characters that strive for wealth. Patches was always a favorite (despite getting kicked by him into a hole I still loved him) and the armourer dude in ds2 who loses his mind and makes me sad. They all have kinda sad endings but that makes them even better characters
