Seiryuu, a shikigami bound to Kaoru Okita, stands among the four legendary celestial beasts—Genbu, Byakko, and Suzaku—summoned as her combat allies. Kaoru, daughter of Soji Okita and a half-human, half-kitsune hybrid, channels her supernatural lineage to command these mythic entities against rogue yōkai and adversaries. Though integral to her tactical arsenal, Seiryuu’s unique attributes remain undefined, functioning solely as an extension of Kaoru’s strategic will without independent history, personality, or narrative agency beyond its summoned role.
