Among the many agents of Border, Osamu Mikumo stands out not for raw power, but for something far more compelling. Nicknamed 'Plain Glasses' due to his below-average Trion levels and modest combat talent, he might seem unremarkable at first glance. Yet this seemingly ordinary teenager commands Tamakoma Second with remarkable tactical ingenuity and unshakable composure, effectively leading elite fighters Yuma Kuga and Chika Amatori through fierce competition. Driven by an unwavering commitment to protect his teammates and fulfill the promise of a distant expedition, Osamu consistently outsmarts stronger opponents, proving that true leadership is forged through strategy, conviction, and relentless growth.
