So I will keep it short, because not much thing to say. I only suggest to swap Nobushi and Hitokiri headgear, but not entirely. I think the fox mask fits Nobushi much more, and I see no connection between an executioner (Hito) and foxes. I would really like to see a mask only headgear on Nobushi without helmet, with the standard headgear type hair.
I hope this reaches someone o/
