Kyoka Kagami administers the Shoshidai organization, tasked with dispatching Chrysalises to combat threats from Busoma and cursed weapons. She possesses hip-length brown hair, grey eyes, and wears oval-shaped glasses, marked by a mole beneath her left lip. Her standard attire is the Shoshidai administrative uniform.

Significant loss defines her past: her mother died in Kyoka's childhood, leaving her solely in the care of her father, Takuma Miura. Takuma later became Shoshidai's administrator himself, only to fall victim to possession by the cursed sword Zsoltgewinn. He transformed into a Busoma and abandoned her, forging her serious and stoic nature [citation:].

As administrator, Kyoka makes critical operational decisions. She authorized Naoki Miki's mission to retrieve the Azoth Sword and introduced Marcus Lithos to Shoshidai headquarters. Facing escalating dangers, she ordered the reawakening of their most powerful asset, Chrysalis Seiya Ichijo. Confronted by Zsoltgewinn and recognizing her father within the Busoma, she permitted Seiya and Gai Ogata to engage him when conventional anti-Busoma measures failed.

Her desperate efforts to save her father ended tragically. She acquired a purported cure for Busoma transformation, but her intervention failed. Fully consumed by the sword, Zsoltgewinn fatally stabbed Kyoka. She bled out alone, fulfilling her fear of dying without saving her father.

Her story concludes with this fatal encounter, underscoring her unresolved quest for familial reconciliation amid her duties.
