hmm! there is the last character of "main fighter character's" in Soie & Tamahagane
His (may be temporary) name is Miya.
he will appear a bit further than the 3 others in the story.
It's an amazing character, so crazy a bit insane in his head.
well if u had reconized him, haha it's a very popular real life person that i admire a lot for his style and songs of courses (zoom a bit more the face if try to remember who is it).
His weapon is a very heavy japanese Yari's head linked to a long chain. I imagined a fun combat style for him. can't wait to draw him in scans!
cya & take care!
