wind punch

As he thought, Accelerator spun his body swinging a clenched fist.
His arm was rumored to be able to kill someone just by touching them.
“...!!!???”
Hamazura immediately swung his body to the side in an attempt to evade.
Accelerator’s arm did not actually make contact.
However, an explosive wind of unknown origin appeared and blew Hamazura away. He
flew more than two meters through the air before slamming into the hallway wall.
Unnatural strength entered his finger holding the trigger and he fired a meaningless
shot into the ceiling.
