Well, the game's been out for a while, and I completely forgot about it. lol
Anyway here are some Nicovideo vids of some guy clearing the single player mode using Galford:
You need an account to watch, but hopefully someone can put them on Youtube or something (I have no idea how to do it).
A couple of new characters are shown: Draco, a gunslinger from the Old West (which makes no sense since cowboys shouldn't exist at the time this game takes place) and the final boss, a guy called Golba/Golva who is voiced by Norio Wakamoto and uses some kind of European fencing style.
I haven't checked to see if there are any actual match vids anywhere.
On a side note, the Nicovideo comments are hilarious.
