Ryo studied the situation carefully. He was unarmed, the other guy had a sword...okay, yeah, there could be a problem there for some people. And for the unconscious NPC's sake, perhaps a bit of a distraction in order. "Well, if you don't..."

He spread his arms as though he were about to receive something. "HENSHIN!" If Sasuke watched, he would see Ryo glow a weird shade of green and sort of shift into some sort of humanoid bug-thing. The transformation was quick, almost instantaneous.

Ryo, now in his Rider form of Gills, growled softly at Sasuke to let him know just what he was getting into.
