sword wave of stone

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.

“GASTTH. (Go and shape this to my hand.) TFIAS. (This flame is a sword.) TRIC! (The
role is conviction!)”
Rune-engraved cards danced through the air.
At the same time, a red sword of flame burst forth from Stiyl’s right hand. He swung it
horizontally at the incoming wave of stone. Ignoring Kamijou right next to him, for the
most part.
“Agh!!”
Kamijou quickly crouched, and a moment later, the tip of the flame sword collided with
the stone fragments. Then, the flame lost its form and the whole thing exploded. The
explosion had been directed away from them, so it spared Kamijou, who was directly
under it. It wiped out the wall of asphalt stretching toward them, blowing it away.
