[Touma was able to handspring backwards over his weapon to avoid the leg sweep. He was surprised by the strength to be certain, but, at the same time, not. He'd fought supernatural beings before, so unusual strength or power wasn't completely foreign to him.
But, it did give him pause about Ashura's fighting ability. The shape of his opponent's ears had been a little telltale to start, but this strength factor added a whole new level of realism to the fact that Ashura wasn't going to be like another kid sparring against him in a normal dojo.
Of course, then he also realized he'd grabbed the other end of his sword. Oops... Switching back to a sword grip from a staff one, he settled his stance once again before coming at Ashura with a quick attack to the left arm, followed by a reversed spin to attack the right.]
