Kōhei Izumi (出(いず)水(み) 公(こう)平(へい), Izumi Kōhei ^?) is the No. 2 Shooter and member of Tachikawa Squad.

Appearance[edit source]

Izumi is a boy of average height. He has neck-length dark blond hair, and also golden eyes. When he is in trigger mode, Izumi wears a black long coat with thin red stripes on it and a Border emblem patch on his left sleeve, just like the rest of his Squad.

Personality[edit source]

As shown in the manga, Izumi is a reckless person. He wanted to raze the whole battlefield with Meteor in just to lure Arashiyama Squad out. Tōma also said that Izumi always comes up with harsh ideas.^[1] However, this personality doesn't always show up, and he is actually quite intelligent and a good strategist. Izumi is a humorous person, often making jokes whether it be casual or in battles. He is slightly immature when he is around his friends.

Trivia[edit source]

He likes fried prawns, croquettes, oranges, and using Full-Attack.
He is the one who discovered the composite bullets.^[9]
In Japanese, his name Izumi (出(いず)水(み), Izumi ^?) means Flood and Kōhei (公(こう)平(へい), Kōhei ^?) means "Fairness" or "Justice"
He ranked fifth in the 1st Valentine's Day Ranking and first in the 2nd Valentine's Day Ranking.^[10]^[11]
