Ka Rin serves as a Great General and second-in-command of the Chu Military, holding one of Chu's two prime minister positions. She possesses a tall stature rivaling Kan Mei's height, a voluptuous figure, short black pixie-cut hair, brown eyes, and fair skin. She often grasps her chest when excited, displaying pride in her appearance and considering herself the pinnacle of beauty. Her personality blends ruthlessness, unpredictability, and cunning. She speaks abusively to those she deems inferior and exhibits cruelty, executing a lieutenant for perceived incompetence. Ka Rin harbors a complex about her height, threatening death to anyone who comments on it. She displays overtly perverse tendencies, openly offering sexual rewards to successful men and expressing enjoyment in bedroom dominance games, maintaining an obsession with her physical appeal and believing no man can resist her. Commanding the 2nd Chu Army during the Coalition Invasion Arc at Kankoku Pass, Ka Rin absorbed remnants of the Rin Bu Kun Army. She orchestrated multifaceted assaults using war chariots and elephants as diversions. Her core strategy deployed 5,000 elite soldiers through a hidden mountain passage to flank Qin forces inside the gates – a plan thwarted by Ou Sen. She attempted to assassinate Mou Bu to protect Kan Mei by deploying her brother Ka En, but Mou Ten's interference caused failure. Following Kan Mei's death, she reveled in the prospect of diminished rivals. After the coalition's retreat, Ka Rin returned to Chu and was promoted to military second-in-command. Her army expanded significantly, commanding over 300,000 soldiers. She later agreed to a treaty with the State of Ai, diverting Qin forces to the border in exchange for wealth. When Ai fell, she lamented missing an opportunity to defeat Mou Ten. Following Shun Shin Kun's death, Ri En appointed her prime minister. She stabilized Chu's political landscape within a month, demonstrating aptitude beyond military command. In subsequent conflicts, she analyzed Qin-Wei alliances and deployed forces to counter Qin, including ordering Haku Rei and Kou Yoku to reinforce Juuko. She later dispatched Kou Yoku to invade southern Qin and capture Keifu. Ka Rin possesses exceptional physical strength, evidenced by killing a lieutenant with a single kick. Military statistics consistently rate her strength in the 90s, with intelligence and leadership scores between 92–98. She excels in warfare through deception, misdirection, and exploiting psychological weaknesses. Her elite soldiers ranked among Chu's strongest. Politically, she swiftly consolidated power upon becoming prime minister. She maintains fraught relationships with subordinates, habitually abusing lieutenant Bam Yu. She oversees commanders including her brother Ka En, Kou Yoku, Haku Rei, and Gou Toku. Despite her harsh methods, her soldiers exhibit high loyalty and combat skill.
