takes a gravel beating

The gravel sprayed at him at close range from the opposite direction than he had
expected. It was like running into a truck that was moving at 100 kph while moving at
100 kph yourself. His own actions had doubled the damage that stabbed into his back.
His breathing stopped as if he had been struck with a bat in the back and he pathetically
collapsed onto the ground.
The sound of objects slicing through the night sky continued.
Kamijou looked up and saw multiple steel rails flying toward him.
(Wha-...?)
Kamijou immediately tried to roll out of the way, but the rails landed on all sides of him
simultaneously. As if he were being beaten by 5 or 6 people, gravel assaulted him from
all sides.
He could not defend against or evade that. Having lost all options, Kamijou could only
sit there dumbfounded as over 100 small rocks stabbed at him. His body was knocked
about making him look like a shrimp that had been brought onto land.
“Gh...gheah...! Ahh...aahhh...!”
Even so, Kamijou managed to grab one of the steel rails sticking into the ground nearby
in order to stand up. His legs were still shaking from the damage leftover from Mikoto’s
lightning attacks and his mouth was filled with the taste of blood.
