Yeah, the SSIV cast is in there, plus clones of Nakoruru, Haohmaru, Ukyo, Genjuro, Kazuki, and Sogetsu, and a few new characters, one being a massive demon. I call
Tokugawa, and i might be up for some LB2 and such tonight.
I think the clones are supposed to be from the demon world or something to do with Amakusa, but we'll have to wait a little while to find out, since the US version has NO CUTSCENES.
At least you can still commit suicide. :D
