Who in the heck is Ryofu? If you mean Ryoko, she's one of my favorites along with Brocken (yeah, I know, real original. But he reminded me of a comic charicter from JoJo's Bizarre Adventure part 2, that I liked), Janne, Muscle Power, J.Max, and Erik ("Eggel Hemming!"--whatever that means). Oh yeah, and Captain Kidd. And Hanzo.
I wouldn't say WH was my favorite series, but I can't think of one character in WH2 that I didn't play as and enjoy.
If you didn't mean Ryoko, and Ryofu is a character that appears in WH2J or WHP, then put Ryoko on your list and I'll vote.
