More fun with Luka. ^^ I don't know Claire and Silvia, but I know Trish and Ammy. ^^ Personally, I think Luka should be more worried about the girls than their guys. Ammy especially, because I think she'd troll him worse than Bayonetta does. >) (And that's saying something! )
Waka isn't a god. Ammy (short for Amaterasu) is. He does have some schweet moves though, his flute is Pillow Talk. Yes, that Pillow Talk, the one you get for beating the game on nonstop infinity climax difficulty. He dual-wields it with an ordinary katana.
I suggest you get it. Demand for the game has recently increased due to Ammy's appearance in Marvel vs. Capcom 3 as well as a popular person on youtube LP'ing the game, so Capcom has pumped out a few new copies.
On an unrelated note, Waka could still pwn Luka any day.
