spear stab

He casually swung his hand horizontally and the white blade followed suit. The giant
blade evaded past Kamijou’s right hand and lunged at his body.
(Oh, shi-!?)
He lacked the time to even finish the thought.
The blade’s width was thicker than his thumb. He felt it press up against his skin and dig
in. Pain exploded about him.
Kamijou’s body doubled over from the force of the guillotine and he was launched into
the side wall.
Shortly after he heard a loud thud, he heard a painful cracking noise from his body.
(...!?)
He was unable to speak. The force that was pinning his stomach and back had left him
breathless.
“Gha...!?”
However, that was the extent of his injuries. Kamijou’s was not sliced in two like the
outer walls.
