Description
Kōji Oki operates as a B-rank Border agent and the sniper for the upper-tier Ikoma Squad. Originally from Ōsaka, he was scouted by Border. Recognized for notable proficiency, Osamu Mikumo listed him among three fighters requiring particular caution during round six, alongside squad leader Tatsuhito Ikoma and Kazuaki Ōji. His tactical value encompasses eliminating targets, suppressive fire, counter-sniping, identifying trion signatures, and tracking Bagworm users. He exploits vantage points accessed rapidly through Grasshopper, granting above-average mobility effective for evasion over short distances though less suited for prolonged escapes. This mobility contributes to his tendency not to reposition after every shot, though he relocates when necessary to catch targets unaware.
Oki displays confidence in his sniping skills, believing he could hit agile opponents like Yūma Kuga and time attacks to intercept Chika Amatori within an interval too brief for her defense. However, he struggles against highly mobile foes like Kuga or Ōji once his position is revealed. Analytically, he predicts shot outcomes by factoring reaction time, distance, and bullet velocity, though this method proved imperfect when Kuga survived a lethal headshot by sacrificing an arm. Oki possesses extensive knowledge of Border Triggers, recognizing Hornet on sight and devising tactics to evade Hound. His reflexes and adaptability enabled him to narrowly survive long-range barrages, showcasing swift Trigger switching.
Personality-wise, Oki presents as easygoing yet flirtatious toward younger girls, frequently expressing a desire for them to be his sisters and claiming difficulty sniping them. Others dispute this asserted reluctance as part of a "good guy" façade, noting his willingness to shoot regardless. During round six, he objected to targeting Chika Amatori but complied when ordered; his subsequent failure stemmed from a lapse in focus when she unexpectedly opted for mutual destruction—severely injuring them both. He later reiterated his inability to shoot someone "as cute" as Chika, invoking his idealized younger sister, though teammates like Isami Tōma dismissed this as hesitation. Oki denies his popularity with girls and remains secretive about this aspect.
In combat, Oki employs a versatile Trigger set. His primary Sniper Triggers are Egret for precision shots and Lightning for suppressive fire. He relies on Grasshopper for rapid scaling and evasion, skillfully chaining pads for directional changes. He maintains Bagworm constantly for radar concealment, structuring his Trigger set to use Sniper Triggers or Grasshopper without deactivating it. His Shield usage involves casting hexagonal barriers at varying distances to block multi-angle attacks. Ahead of round eight, he temporarily equipped Ibis to counter high-trion opponents, successfully using it to eliminate Kazuto Tonooka when limited escape routes restricted the latter's mobility.
Oki's operational history spans multiple B-rank wars. In round six against Ōji Squad and Tamakoma Second, he engaged Yutaka Kashio and Kazuki Kurauchi before targeting Chika. After surviving Ōji's pursuit via Grasshopper, he assisted teammates by shooting off Kuga's arm. His later attempt on Chika resulted in mutual bailout. Ikoma Squad finished third with 34 points. During Galopoula's incursion, his squad deployed south of Border's base. In round seven, he interacted with Chika post-training, reiterating his sister complex. For round eight against Ninomiya Squad, Tamakoma Second, and Yuba Squad, he prioritized Tonooka after deducing the Sniper's role in detonating Chika's Meteor prematurely. After Chika flushed Tonooka into the open, Oki eliminated him but was later ambushed by Shinnosuke Tsuji following a narrow escape from Ninomiya's Hornet barrage. Ikoma Squad concluded the season ranked fourth with 34 points.
