negates building busting hammer

An enormous sound came from Oriana, five hundred meters away. The air around her in
a sphere had churned. A giant invisible hammer shot toward them in defiance of the
distance. It rotated clockwise as it spun toward them, its force utterly destroying the
building she’d been leaning against. It plunged toward Kamijou, turning over the
asphalt as it went.
“!!”
Kamijou’s right hand shot up instantly.
With a cracking noise, the high-pressure wall was blown away, still invisible. Five
hundred meters away, the tiny Oriana, clearly irritated, brought her flash cards back up.
However, the asphalt was still spraying. The wave of stone in the wake of the hammer
closed in on him.
