One Shotter

One Shotter (ー発屋, ̄Wanshottā) is an A-Class rank 22 professional hero for the Hero Association.

Appearance
He wears a jacket that has OneShot written across the arm and a turtleneck sweater underneath. He has a bandoleer wrapped across his chest that carries ammunition for his gun. A mechanical eye patch covers his right eye

Personality
One Shotter appears to be a mostly level-headed, pretty average guy. He often has a vacant or tired expression on his face. When going to assault the Monster Assocation, he worries about the hostage and sympathizes with him for being a high profile target as the son of a rich family. In the heat of battle he maintains a cold and confident face for the most part, but the moment things go south for him he loses it and becomes worrisome again. He appears to have bad luck with his gun jamming, which causes him the most stress.

Monster Association Arc
He is one of the heroes recruited as backups to the main Monster Association strike team. He killed a monster that tried to shoot Twin Tail and monsters that tried to ambush him. He runs behind Puri-puri Prisoner, when another monster attacks him, but he is saved by Green.
