Is it just me or that final boss' sillouete has horns? I wonder if we'll have yet another fighter with an oni as the final boss, heh.
That circle looks kinda different from a normal shimenawa. It looks kinda puffy. Frankly, considering the name of the game, that makes me wonder if that's some kind of intricate, floating flower-crown-circle of sorts. Or maybe smoke.
From what I can tell, too, it looks like she has long hair.
Ofc, it could just be a fake though, but it's nice analyzing stuff. Hehe.
