Domas, a master swordsman of the Bosse Kingdom’s Big Four, wields a strength-centric sword style mirroring King Bosse’s own formidable approach. Charged with training Prince Bojji, he faltered in adapting his methods to the prince’s physical limitations, fostering frustration and emotional detachment despite mastering sign language to bridge their communication. His rigid adherence to brute-force combat and idolization of Bosse drove him to prioritize loyalty to the throne above personal morality. After Bosse’s death, Domas was manipulated by the newly crowned King Daida into attempting Bojji’s assassination—an act that plunged him into searing remorse. He atoned by severing his dominant hand, then rescued Hokuro, a condemned guardsman, forging an uneasy alliance to dismantle an underworld portal beneath the kingdom. This mission ignited conflict with King Desha’s forces, prompting Domas to face them alone to protect his allies. Tormented by guilt, he vacillated between defending his past choices and seeking redemption. His relationship with Hokuro evolved from hostility to grudging cooperation, bound by survival and shared purpose. Despite losing his hand, he harnessed a metal prosthetic to retain lethal combat skill. His journey shifted from blind fealty to a complex reckoning with duty and sacrifice, yet his resolve remained anchored in atoning for his betrayal of Bojji.
