Kue, a shape-shifting guardian bound by divine mandate, was entrusted by Grand Chamberlain Figaro to safeguard and mentor Fandora after her parents perished in Yog Sogoth’s cataclysmic invasion. Tasked with concealing her royal lineage and shielding her from past traumas, he enforces a prophecy casting her as a future savior—a role endangered by the risk of her harnessing the Jewel of Lupia’s power for vengeance.

As a dragon sworn to divine service, Kue wields the Jewel embedded in Fandora’s tiara to morph into myriad forms, including the formidable Fantastic Dragon. Ancient invocations trigger these transformations, granting strategic dominance during interdimensional bounty hunts. His true draconic nature surfaces only under the Jewel’s luminous rays, a manifestation of his sacred covenant.

A pivotal sacrifice unfolds when Kue unleashes the forbidden Jewel’s energy against Yog Sogoth, thwarting the entity’s dimensional conquest at the cost of his own existence. Yet, mirroring mythic cycles, he undergoes a phoenix-like rebirth, resurrected to resume his eternal vow as Fandora’s protector.

Chronicled across the original OVA and companion novels, Kue’s journey intertwines steadfast loyalty with calculated secrecy. By veiling Fandora’s heritage and balancing celestial duty against mortal bonds, he embodies a guardian navigating moral shadows. His choices steer the narrative’s core themes—intertwining threads of destiny and redemption to avert her spiral into vengeance.
