ice armor sword dodge

Kamijou responded by trying to strike the sword with his right hand.
Then, suddenly, the ice armor’s legs broke apart on their own. It began to fall backward
and diagonally across an axis on its thigh portions.
The great sword’s mowing path changed to match—from a horizontal one aiming for his
gut to one thrusting up toward his neck from below. As if to go around his right hand
protecting his stomach.
(Shit...!!)
The burst of wind from the sword blew away the cold sweat on his cheeks.
“Uooohhh!!”
He crouched with all his might.
Several of his hairs touched the sword. They weren’t severed without resistance; instead,
an intense pain shot through him as though the sword had pulled out a piece of his scalp
with it. He heard a terrible tearing noise.
But he had still dodged it.
