Kage, a survivor of the Shadow clan’s massacre orchestrated by political machinations, escaped annihilation as a child through his mother’s sacrifice. Guided through a lethal forest by a countess and her butler, he endured years of solitary survival through theft, later exploited by a mentor-thief whose betrayal ended in the latter’s demise. This forged Kage into a cynical, solitary rogue—until meeting Bojji, a disdained prince whose silent resilience mirrored his own loneliness. Defying initial intentions to rob him, Kage unlocked a unique kinship, deciphering Bojji’s unspoken language. Tasked by royal advisor Bebin, Kage covertly safeguarded Bojji after the prince’s disinheritance. When Bojji’s former mentor Domas attempted assassination, Kage pursued him into the underworld’s depths, aiding Bojji’s training under Despa, a prince honing latent strengths. Amid clashes with monarchs and immortals, Kage’s loyalty was tested. During a battle against Ouken, he unleashed a dormant clan power, swelling to colossal size to devour the immortal—a sacrificial act that nearly killed him. Revived from death’s threshold, he grappled with insecurity, abandoning Bojji’s kingdom to seek strength. Bojji later abdicated to reunite with him, pledging to forge a new realm together. Inheriting Shadow clan traits, Kage maneuvers seamlessly across terrain, melds with shadows, heals rapidly, and stores objects within his form. His knife mastery stems from a thief’s harsh upbringing. Emotion-triggered gigantification, though fleeting, serves as a desperate defense. His bond with Bojji thrives on silent symbiosis, while his rapport with Despa oscillates between bickering and grudging alliance. Kage’s arc traces a jagged path—distrust thawing into vulnerability, then self-acceptance—as betrayals and bonds reframe his purpose from survival to sacrifice. Figures like his mother, the duplicitous thief, and allies like Bebin anchor his metamorphosis from fractured survivor to cornerstone of Bojji’s destiny.
