Reiga, formally titled Karura-ō Reiga, serves as one of the Hachibushu—eight mystical warriors sworn to guard the goddess Vishnu in the celestial realm of Tenkūkai. His Shakti armor channels the divine Garuda, adorned with avian motifs and wings enabling flight. Visually striking, he bears a forehead dot, purple eyeshadow, and gradient blond-to-purple hair, coupled with a theatrical presence and feminine cadence in speech. Chosen as Karura-Oh at thirteen, Reiga wields unparalleled command over Sohma, the spiritual energy underpinning his world. A shrewd tactician, he balances keen intellect with strategic foresight, often guiding the Hachibushu through crises. Though he masks his dedication behind a carefree façade, his loyalty to duty and comrades runs deep. His dynamic with fellow warrior Kuya intertwines rivalry and mutual reverence, climaxing in a desperate battle to free Kuya from corruption. In combat, Reiga employs twin rings and feather-based techniques: "Karula Hanefubuki" unleashes razor-sharp energy feathers like a storm, while "Karula Kayokujin" ignites them into fiery projectiles. He synergizes with the Hachibushu in collective assaults, such as the "Juuoh Mandala-jin," fusing their powers into a devastating strike. Post-conflict, the "Dark Genesis" OVA depicts Reiga adapting to Earthly life as a sushi bar proprietor, blending flamboyant modern attire—like stiletto heels—with his innate elegance. This transition underscores his adaptability, yet his core resolve and wit remain unshaken. While his narrative eschews romance, it emphasizes bonds of brotherhood and the weight of duty. Evolving as a mediator between rationality and empathy, Reiga navigates war’s moral ambiguities with tactical brilliance and unyielding allegiance. His survival across countless battles testifies to his ingenuity, while his choices—particularly in redeeming others—reflect the series’ themes of sacrifice and the blurred lines between light and shadow.
