Turns out Isshin Ashina is a bitch and a half (Not sure if I'm glitching or if he's hitbox porn for NPCs) because for some reason I just can't hit him. He does this dance move and it doesn't matter what I do my attacks go right through him! sucks, and I thought this fight would be easier.
Emma's pretty tough, too.
