Ka Ryo Ten, also called He Liao Diao, survived as a war orphan and final descendant of the Kyuumei Tribe, eradicated by Yo Tan Wa's forces. After her grandfather's death at age five, she endured in Kokuhi Village—a criminal enclave—by scouting for local thugs and betraying travelers for coin. Her grandfather's dying mandate to prioritize survival above all forged her resourceful pragmatism. During the Sei Kyou rebellion, she discovered Shin and Ei Sei fleeing soldiers. She first alerted outlaws to their presence but later bargained to aid their escape for promised riches. Her intervention proved decisive: she wounded adversaries with Muta's inherited blowgun and survived a stab thanks to concealed chainmail, revealing her gender to those who initially mistook her for a boy. Post-rebellion, she rejected Yo Tan Wa's tribal invitation to remain with Shin. Feeling outpaced by strengthening comrades, she pursued strategy. Kyou Kai secured her entry into Shou Hei Kun's Strategist Academy with a recommendation letter branding her a "genius." She graduated with highest honors, rivaling elite student Mou Ki in war simulations after mastering military theory, formations, and logistics. Returning to the struggling Hi Shin Unit, she reversed their defeats by conquering Risei in ten days, cementing her role as chief strategist overseeing supplies, deployments, and tactics. Her ingenuity drove the unit's triumphs: at Kankoku Pass during the Coalition War, she rallied scattered troops and coordinated reinforcements; at Sai, she directed city defenses. She stunned veteran commanders with innovations like the "Hi Shin Unit-Style River Bridge" at Kokuyou Hills—using feints to cross an impassable river. She adapted formations fluidly, modifying wedges for aquatic assaults and deploying psychological warfare like the Hourai formation. Lacking physical strength, she leveraged acute perception, terrain exploitation, and rapid maneuvers. She routinely entered battlefields to inspire troops firsthand, bolstering unit cohesion. Her resilience shone when surviving arrow wounds and torture after Wei forces captured her during the Fire Dragons campaign. Confronted by General Gai Mou about her ambitions, she declared her wish to help Shin achieve his dream and find happiness with him, implying deeper sentiments. Her appearance evolved from a short, disguised child in a straw poncho and cropped hair to a taller, more feminine figure with shoulder-length locks post-Sanyou. She consistently displayed two protruding hair strands and her Kyuumei owl mask, later adding a rank-denoting cape as the unit expanded. Pivotal relationships anchored her journey: Shin as a brotherly figure and motivation; Kyou Kai as the mentor who steered her toward strategy; Ei Sei as a close friend and sovereign. She maintained alliances with figures like Heki and Mou Ki, the latter becoming her academic peer.
