I have a Mitsunari if you're interested, and while I haven't played him before, I've been considering putting together a Kojuro journal lately so I can offer him, too. Bad blood is always my game.

Also - I've got a Sicks from Nougami Neuro, and I'd be interested in trying him against your Kasai or X. Neuro RPers are pretty rare, so I was more than a little excited to see both of them on your muselist.
