Hotsuma...He's got the speed to leave after images of himself. Don't remember Ryu doing that while playing Ninja Gaiden. Then again Hotsuma's sword might kill him while he's fighting Ryu.

Ryu would win if he stalls long enough for Akujiki to eat Hotsuma's soul. But its unlikely to hit Hotsuma since he does his stealth dash thing all over the place.
