Summary
Born in the province of Gen near the Kuto border, Soi is a Nineteen-year-old Seiryuu Celestial Warrior whose true identity is Kaen Haku. Born under the Star Room, she was sold into a brothel due to her family's poverty before being rescued by Nakago at age twelve. This event sparked an unrequited devotion, as she remains his most loyal follower despite knowing he exploits her to recover and heighten his chi. Her powers include Feng Shui abilities to control lightning and induce electromagnetic fields, alongside skills in Fhangzang and chi raising techniques. Although she presents as a formidable, masculine-armored fighter, she hides a kind, feminine heart. While hostile toward Suzaku, she feels sympathy for Miaka Yuuki, driven by jealousy of Yui and Tamahome. She envies their bond and even admits she was not assaulted by Nakago, claiming she would have killed Miaka if she had been. Like Tomo, she avoids harming Miaka directly but will do anything for Nakago.
