notices his hand getting cut as he uses it to defend, dodges

Kamijou stopped running and focused on defense. The large sword came flying
horizontally for his neck and he immediately held up his right hand and tried to negate
Marian’s magic.
However, he noticed something partway through.
The end of the little finger on his right hand was slightly cut.
The meaning of the few drops of blood was clear.
“I can’t block it with Imagine Breaker…!!”
“Didn’t we tell you we have countermeasures?”
He forcefully stopped the action he had started to take and felt his backbone and muscles
straining as he did so, but Kamijou managed to change what he was doing. He swung his
upper body to lower his overall posture.
The large gray sword passed directly above him.
The chain link fence behind him was torn to shreds, but the blade did not follow him for
long. The large sword must have only been able to last about three seconds.
