Yagyuu is as unflappable as always. Of course he doesn't rise to the bait-- that would be too easy. Nor is he ignoring it in hopes it might simply disappear. The man is smart enough-- and knows him well enough-- to know the challenge only makes him more interested. If Yagyuu were an easy target, it wouldn't be fun.

But what really makes it engaging is that he welcomes the game. Yagyuu's bantering response is all the proof anyone should need of that. Challenge accepted.

"Wouldn't that be a loss," he says, his eyes fixated on Yagyuu's. Never mind they're supposed to be following a finger.
