Asch's shoulders slump just a little--in tired annoyance, not defeat. He's sick of getting hassled by his invisible visitor over a bunch of shrubbery. The thought of just walking away and finding a different patch of ground to terrorize, but he waves it away. He doesn't want to try to retreat until he can be sure he won't get jumped on the way out.

"There are worse targets to use than bushes." He knows a lot of people wouldn't have bothered finding a less flammable part of the forest to practice in, but he doesn't feel like comparing himself to hypothetical somebodies--especially not out loud. "All you're doing is being annoying." He makes a sharp chopping gesture with his hand as he speaks. "If you're not going to show yourself, then go away and bother someone else."

Cause that's... totally going to work.
