Keizō Mamiya

Keizō Mamiya is a B-rank Shooter and the captain of Mamiya Unit.

Appearance
Mamiya is a light-skinned young man of average height and build. He has medium brown hair gathered in slightly messy, soft spikes. Like the other members of his unit, in his trion body he wears dark pants, a lighter jacket with a high collar, and boots of the same color, as well as dark-rimmed goggles with square, protruding lenses.

Introduction Arc
Mamiya Unit is presumably involved in the extermination of all Rads in Mikado City.

B-Rank Rank Battles Arc
In the round one lower-tier rank battles, his unit goes against Yoshizato Unit and Tamakoma Second. They are easily taken down by Yūma after Chika destroys their hideout.

Abilities
As the leader of a B-rank unit, Mamiya should be more skilled than a C-rank agent and have a modicum of leadership and strategic abilities. His unit's foremost tactic is a combined attack which sees the three Shooters focusing their Full Attack Hound on a single target. This technique, called Hound Storm, was extolled by Ken Satori as a very powerful attack. However, the whole unit was easily defeated by the combined might of Chika and Yūma without managing to put up any form of resistance.
