hundreds of air drills

They ate into each other and become a single mass before exploding out in a fan shape
like a shower. Hundreds of pointed air drills shot toward Kamijou all at once.
He could defend against all of them with just his right hand.
“Ahhhh!!”
As he charged forward, Kamijou forcibly twisted his legs so he could roll to the side with
all his strength. With a dull sound, the asphalt was torn up for several dozen meters
behind him. The arm of his school uniform was ripped off and he felt the skin tearing as
well.
