Kazuto let out a small sigh. He disliked showing off, finding anything too flashy to be a bother. He preferred practicality over anything, though if they were asked to show off the upper limits of their powers then that's what he gave them. He glanced around, looking for something to absorb. Not water, as it was harmful to him. He could drink it, but touching it outside of that, especially something as large as a pool, was a definite no for him. Concrete, no. Too destructive. He glanced around at the other students, observing their quirks before sighing. There really wasn't anything to absorb, so he simply crouched and touched the ground, To most of them, there wouldn't be any change, but to the observant ones such as their teacher, there was a change in posture when he stood back up. He held raised one foot before stomping it, and suddenly on the far side of the field a massive wall of concrete formed, nearly as tall as the UA building itself. He was left panting lightly after the exertion of doing it though, and he was completely empty now.
