Sword strikes continue for dozen meters

In an instant – truly only an instant – Kanzaki’s right hand blurred and disappeared like
a bug in a video game.
With a roar, something flew towards Kamijou with frightening speed.
“!?”
Kamijou felt like giant laser guns were being fired from all directions.
It was like a giant tornado made up of blades of air.

Kamijou Touma watched as that typhoon sliced the asphalt, the streetlights, and the
trees lining the street at set intervals to pieces as if with an industrial water jet cutter. A
fist-sized piece of asphalt flew through the air and struck Kamijou’s right shoulder. That
was enough to send him flying and almost knock him unconscious.
Holding his right shoulder, Kamijou looked around while moving only his eyes.
One...two...three, four, five, six, seven. A total of seven straight sword cuts continued for
a few dozen meters across the flat ground. The sword cuts came in at many seemingly
random angles and looked something like fingernail scratches on a steel door.
