Description
Yutaka Kashio is a B-rank Attacker in Border, serving as a combatant in Ōji Squad. Raised to address his parents with extreme politeness, this formality extends to interactions with superiors. Before joining Border, he experienced no significant failures, but suffered a crushing defeat against Ai Kitora after enrollment.
He possesses light skin, a medium build, short dark hair with a middle part and choppy bangs, thick eyebrows, and almond-shaped eyes with dark irises. His standard Border uniform is a black double-breasted jacket with a Korean collar, plain button epaulets, and seven square buttons. He wears the jacket open over a white shirt, sleeves rolled up to reveal inner white and light blue stripes. Angular pockets with blue stripes adorn the chest, and the B-rank logo appears above the left pocket. He pairs this with black pants rolled above matching boots.
Personality-wise, he reacts strongly when expectations are unmet but calms quickly after explanations. He demonstrates a keen sense of responsibility, particularly regarding his duties, and maintains seriousness toward academic studies. His upbringing contributes to a stiff formality when communicating with authority figures.
Throughout Border operations, Ōji Squad participates in rad extermination in Mikado City. During the Second Large-Scale Invasion, Masafumi Shinoda withheld the squad from deployment to prevent member capture. Kashio engages extensively in B-Rank Wars. In Round Two (February 5), Ōji Squad faced Azuma, Katori, and Yuba Squads in a four-way match. They placed fourth in Round Three (February 8). Round Four (February 15) was fought in the day division against Ikoma and Yuba Squads, with Ōji Squad retaining fourth place with 22 points. During Galopoula’s Blitz (February 19), the squad faced Ninomiya, Ikoma, and Suzunari First in the day division, again placing fourth; they deployed that night to intercept Galopoula invaders south of the base. Ōji Squad dropped to fifth place after Tamakoma Second advanced in Round Five. In Round Six (February 22) against Tamakoma Second and Ikoma Squad, Kashio questioned Ōji’s choice of Cityscape A map but accepted the risk-minimizing rationale. During combat, he spotted Osamu Mikumo’s wires, cut them, and pursued Chika Amatori. He was immobilized by her Lead Bullet and defeated by Osamu, resulting in Ōji Squad scoring three points. Round Eight (March 5) saw them face Azuma and Kageura Squads in Exhibition Hall, placing third with three points.
Within Ōji Squad, teammates address him by nickname without honorifics. The squad shares a competitive interest in chess, practicing secretly after Ōji introduced the game. Kashio serves as student council president at a private middle school and is a senior to Kōda Squad members.
His preferences include lasagna, Ramune, potato salad, and studying. His nickname and squad monitor icon—a Casio watch face with his bangs—derive from a pun on "Casio." Authorial commentary suggests his defeat by Ai Kitora may have sparked a crush on her.
