Description
Kōhei Izumi is a human male agent affiliated with the defense organization Border, serving within its Headquarters branch as a key member of the Tachikawa Unit. He holds the rank of A-Class and operates primarily as a Shooter. Standing at an average height of 175 cm, he possesses neck-length blond hair and distinctive yellow eyes. His trion body appearance features the standard Border long coat adorned with thin red stripes and an emblem patch on the left sleeve.
Izumi exhibits a complex personality, often displaying recklessness in combat, such as proposing the harsh tactic of razing entire battlefields with Meteor to flush out opponents, a suggestion noted by squadmate Isami Tōma. Despite this impulsiveness, he possesses significant strategic intelligence and adaptability, enabling him to analyze opponents' tactics and devise effective countermeasures. Outside intense situations, he reveals a humorous and slightly immature demeanor around friends.
As Border's No. 2 Shooter, his combat abilities are defined by exceptional trion levels (rated 12/14) and mastery over all bullet-type Triggers. His key proficiencies include:
* **Composite Bullet Creation:** Izumi invented composite bullets and generates them in approximately two seconds. His known composites are Tomahawk (Meteor + Viper) and Gimlet (Asteroid + Asteroid), with Gimlet exhibiting sufficient power to penetrate Rabbit armor, exceeding Ibis' destructive capability.
* **Trigger Specialization:** He utilizes Viper with advanced pathing flexibility comparable to specialist Rei Nasu, enabling complex trajectory adjustments for stealth attacks or area denial. His high trion output allows Meteor to cause widespread environmental destruction and Asteroid barrages to overwhelm defenses through sheer volume. He employs Hound for precision interception, demonstrated by shooting down all projectiles from Hyrein's Alektor.
* **Defensive Tactics:** Shield deployment leverages his substantial trion reserves for durability, briefly withstanding combined assaults from multiple A-rank agents. He strategically uses Full Guard to bait opponents into revealing positions.
Izumi participated in critical Border operations. During the Black Trigger Retrieval Arc, he joined the strike force targeting Yūma Kuga. His team engaged Arashiyama Squad, where his aggressive tactics, including attempts at large-scale destruction to eliminate cover, were tempered by Miwa's caution and ultimately thwarted by coordinated counterattacks.
In the Large-Scale Invasion Arc, he assisted Tamakoma First against the Neighbor Ranbanein, directing battlefield movements and using composite bullets to corner Ranbanein toward sniper positions. Later, while protecting C-rank trainees, he engaged Rabbits, collaborating with Osamu Mikumo and Chika Amatori. Upon Hyrein's arrival, he prioritized evacuating trainees while engaging Hyrein alone, employing environmental destruction like collapsing buildings to expose Hyrein to sniper fire and initiating a stamina-draining battle before bailing out under concentrated attack. These actions earned him an Outstanding Service Reward.
Subsequently, he voluntarily mentored lower-ranked trainees during the invasion's aftermath.
Trivia notes include his preferences for fried prawns, croquettes, oranges, and Full-Attack tactics. His surname "Izumi" translates to "Flood," while "Kōhei" means "Fairness" or "Justice." He ranked fifth in Border's first Valentine's Day poll and first in the second. Fandom perception includes his membership in the "Idiot A-Rank Trio" alongside Yōsuke Yoneya and Shun Midorikawa, highlighting the contrast between his combat intellect and occasional impulsiveness.
