Komasa holds the rank of Third Division Commander in the Ninku organization, wielding the Wind Element technique. His combat style revolves around manipulating atmospheric currents to form razor-sharp blades from the air, enabling both offensive assaults and defensive tactics.

Once a dedicated Ninku commander, he fell into enemy hands during the conflict that dissolved the Ninku, captured by the Imperial Marines. Subjected to intensive brainwashing during imprisonment, Komasa lost his memories and allegiance, repurposed as the Marines' weapon codenamed "Wind Knife."

Operating under this conditioning, he executed missions against his former allies. A critical clash with Fuusai, the First Division Commander, ignited fragmented recollections of his identity. This painful resurgence of suppressed memories unfolded through flashes of his past bonds and life. Ultimately breaking the Marines' control, Komasa reclaimed his loyalty to the Ninku cause.

He rejoined the protagonists in opposing the Imperial Marines and Emperor Hamma. Redeemed, Komasa deployed his wind techniques decisively in pivotal battles alongside fellow commanders, directly advancing the Ninku's goals during the final confrontations.
