reflects bullet

He stabbed the gun toward her chest, rising and falling with her shallow breathing. He
placed his finger on the trigger. Just by moving his finger a bit, his special bullet, the Shock
Lancer, would tear her delicate body apart completely. He wasn’t thinking about where
he’d shoot, nor how many rounds. He pulled the trigger, content to keep on firing until
the gun was empty.
The sound of the gunshot rang out in the night.
But that round didn’t pierce the girl’s body.
“—Not gonna happen, you pile of shit!!”

The corpse had risen.
The boy, blood steadily flowing from his torn forehead, had reached out with his hand to
block Amai’s gun. The bullet had been cleanly reflected back into the muzzle, and the
handgun exploded from within. It ripped through the wrist holding on to the gun.
“Uhg, ghu...aaaahhhhhh!?”
He grabbed his left hand onto his right, which had been cut up like a pomegranate, and
stepped away from Accelerator.
