At the sudden blast of dust Tonbokiri makes a small noise of surprise in his throat. This is far beyond just kicking up dirt to distract an opponent. It is also a tactic that he regards as rather low, but he should have known that ones from other worlds would have different ideas of what 'proper' tactics are.

He jumps backwards as powerfully as he can, intending to get clear both of the dust cloud and of the attack that is quickly incoming. Sometimes it is best to press the offensive, and sometimes you must wait for a better chance. Crystal-people must be more impervious to elements than he himself is with his human body. He will not let Cairngorm keep such an obvious advantage.

Tensing his stance and narrowing his eyes against the dust as he jumps clear of it, he can only rely on his senses to tell him what move Cairngorm will make. Low. To his legs, is it?
Wanting to gain more information about his opponent, he prepares himself to block and counter. But given how easily Cairngorm had brought up that dust cloud, he sets himself to block a heavy blow.
