Komachi Oba, a spirited member of the Imperial Combat Revue’s Wind Division, juggles dual roles as the group’s gift shop entrepreneur and field medic. The 23-year-old Osaka native stands at 145 cm, her youthful appearance belying her sharp wit. Her vibrant style includes spiky orange hair swept into twin ponytails, matching orange eyes, and a practical outfit: a white sleeveless shirt, shorts, and a sunburst-yellow apron. Rollerblade-wheeled sandals let her zip between customers and comrades.

Her personality marries sharp business acumen with heartfelt empathy. Rapid-fire speech and her trademark slogan—“From toilet paper to airships, I’ve got everythin’ ya need!”—fuel her relentless promotions, though Kaoru Rindo’s budget oversight keeps her ambitions in check. Behind her profit-driven hustle lies compassion: she mends teammates’ injuries, like Sakura Amamiya’s battle wounds, and offers solace during emotional downturns.

Though her pre-Revue past remains shrouded, Osaka’s mercantile influence sharpened her trade instincts. Unspecified medical training qualifies her as the Wind Division’s healer. During missions, she seamlessly transitions between shopkeeping and mission-critical tasks, such as dissecting photographic evidence from the Moscow Combat Revue’s destruction for Azami Mochizuki.

Komachi plays pivotal roles in pivotal events—co-hosting the Combat Revue World Games with Reiji Shiba and joining the climactic clash against Valery Kaminski. Her interactions often bridge pragmatic and idealistic factions within the Revue, using her bartering finesse to forge unity while ensuring the Theater’s logistical demands stay met.
