Hokuro serves as a low-ranking Bosse Kingdom knight defined by his inexperience in battle and deep compassion. He mastered sign language to bridge communication with Prince Bojji, spurred by a bond forged when the prince consoled him during his grief over his mother’s death—a kindness that solidified Hokuro’s lifelong devotion. Tasked with guarding Bojji alongside Domas, his duties deepened beyond protection when Domas betrayed the prince, hurling him into a chasm. Hokuro challenged Domas in a fierce duel, resulting in Domas severing his own hand as penance—a pivotal moment that forced Hokuro to confront his rage and embrace forgiveness. After surviving the assassination plot, Hokuro returned to expose Daida’s role, only to be condemned to death by Queen Hiling for his perceived failure. Rescued by a remorseful Domas, their reconciliation forged a partnership of mutual growth: Domas trained Hokuro in advanced combat and gifted him a crossbow, emblematic of his tactical and physical progression. Amidst the kingdom’s political upheaval, including the looming threat of the Underworld passage beneath the castle, Hokuro’s training crystallized into an oath to shield Bojji unconditionally—a vow bolstered by Hiling’s conditional pardon. His evolution from a tentative guardian to a resolute warrior underscored the interplay between unyielding loyalty and cultivated resilience.
