Charles Karino, a mercenary aerial pilot of Levamme and Amatsukami descent, endures relentless racial prejudice as a bestado in the Levamme Kingdom. His mother, a nursemaid for the del Moral family, and his Amatsukami father faced destitution after her abrupt dismissal, culminating in her death during his youth. These struggles forged his resolve to rise above societal barriers, driving him toward aviation—a realm he viewed as unbound by caste or heritage.

Renowned yet unacknowledged by Levamme’s military elite due to his mixed blood, Charles relies on unmatched aerial prowess and tactical brilliance to outmaneuver adversaries. He commands the *Santa Cruz*, a retrofitted reconnaissance seaplane, defying its mechanical shortcomings through audacious maneuvers and precision.

Tasked with covertly escorting Princess Fana del Moral through perilous skies, Charles maintains detached professionalism until shared adversities unearth a buried past: as a child, he once tended the del Moral gardens, unnoticed by the young Fana. Her empathy and defiance of ingrained bigotry challenge his hardened worldview, kindling mutual admiration and latent affection.

Though deeply drawn to Fana, Charles prioritizes duty over desire, rebuffing her romantic overtures to honor Levamme. Upon completing the mission, he spurns his payment, repudiating the kingdom’s exclusionary ideals before vanishing without trace, his story expunged from official records.

Standing tall with a casual air, Charles sports short black hair, navy-blue eyes, and a weathered military uniform accented by flight badges and goggles. Childhood poverty left him in frayed garments, a stark contrast to his later stature.

His legacy lingers in Fana’s subsequent diplomacy, which channels their shared trials into bridges for peace—a silent testament to his internal clash between obligation and yearning, and his steadfast dedication to causes greater than himself.
