Yes, this asshole got a design update again. XD For one thing, I could never draw his tattoos consistently, so I changed their design to be easier to replicate in multiple drawings. For another, his backstory and homeland have always been inspired by the indigenous Ainu of Hokkaido, and yet I always drew him in what amounted to a kimono, a traditionally Yamato Japanese garment. I decided it would be more faithful, and honestly more interesting as a design, if he wore one of the attush tunics of the Ainu.
I did my best to research the matter as thoroughly as I could, though there is sadly a rather small supply of references available in English. Definitely feel free to reach out if there is something I've gotten wrong and I'll correct it!
