Minami Ōi holds a pivotal role within the Shinagawa Tribe as Yutaka Gotanda’s trusted secretary, spearheading logistical and strategic oversight in both corporate and combat arenas. Her expertise lies in deploying cutting-edge XB Gear to dissect adversaries’ weaknesses mid-battle, underscoring a methodical approach grounded in data-driven precision. Her allegiance to Yutaka remains absolute, rooted in admiration for his visionary leadership and tactical genius—a loyalty solidified after she chose to accompany him upon his exit from the tribe following Ichinose’s ascension.

In conflict, Minami operates as a combat support tactician, wielding a dual-function drone that toggles between mending injured allies and assaulting foes. The device autonomously triages allies based on injury severity, channeling restorative energy before pivoting to unleash targeted strikes or area-of-effect barrages. Her arsenal includes deploying temporary shields, disrupting enemy formations with Shock-inducing attacks, and orchestrating battlefield control through calculated debuffs—a toolkit highlighting strategic adaptability over raw martial prowess.

Beyond warfare, she spearheads advancements in the tribe’s XB technology, merging technical ingenuity with the faction’s ethos of innovation. While her demeanor exudes clinical professionalism, fleeting glimpses of a hidden fondness for whimsical aesthetics subtly contrast her otherwise austere pragmatism.

Her story intertwines with Yutaka’s post-tribal endeavors, aiding his founding of G&O Company to redefine their ambitions. Though specifics of their ventures remain undefined, her actions consistently mirror a disciplined focus on organizational efficacy and unwavering fidelity to Yutaka’s objectives, devoid of personal divergence or ideological friction.
