Princess Moon, called Kaguya in her Japanese origins, reigns as the moonborne empress commanding rabbit-eared lunar beings. After her failed Earth conquest a millennium past—thwarted when the first Ryuujin severed her ears to cripple her powers—she lay dormant until reawakened by Yaiba Kurogane’s Dragon Orb. Launching a renewed invasion via bamboo-spired warships, she harvests the youth of Earth’s women to sustain her beauty, a parasitic process that withers victims to husks while briefly rejuvenating her skeletal form into a lithe figure clad in obsidian-purple leotards, rabbit-eared headpieces, and armored capes. Her restored might peaks upon absorbing Sayaka Mine, the Dragon Maiden’s reincarnation, morphing her into a colossal amorphous entity fused with her followers and the planet—a writhing mass crowned by ten hydra-headed rabbit appendages. To counter this threat, adversaries Yaiba and Takeshi Onimaru unite, battling her mastery of energy blasts, elemental forces, storm conjuring, and fusion abilities. Each victory proves fleeting unless her 24-hour cycle of essence-draining is disrupted. Post-defeat, pragmatic survival instincts drive Kaguya into an uneasy pact with Yaiba’s faction against existential foes like Yamata no Orochi, even merging briefly with Sayaka to amplify their shared power. Once crises abate, she retreats moonward, vowing ecological restoration for her realm. Though her name echoes the celestial princess of *The Tale of the Bamboo Cutter*, this Kaguya’s legacy orbits conquest and metamorphic prowess, eclipsing the folktale’s wistful motifs with ambitions etched in war and survival.
