Kaine commands the Zhao Military as a pivotal member of the Ri Boku Army, balancing roles as Ri Boku’s chief bodyguard and most trusted vassal. A native of Zhao’s northern Ganmon region, her childhood ended when Xiongnu raids claimed her parents, forging a vengeful resolve tempered by survival. Though initially skeptical of Ri Boku’s cautious strategies against the Xiongnu, she aligned with his vision upon discovering his own history of loss and his focus on long-term stability over impulsive vengeance. Her upbringing in Ganmon’s rugged mountains honed expertise in dual blades and horseback combat, skills that cemented her battlefield reputation. After Ri Boku’s exile and resurgence, she aided his military reconstruction, evolving into his steadfast protector and shadowing his every political and martial move. At the Battle of Bayou, she crossed blades with Ka Ryo Ten, an opposing tactician, but defied expectations by sparing her through a nonlethal strike—a decision that ignited a clash with Ten’s ally Shin. Her devotion to Ri Boku borders on recklessness, exemplified during the Battle of Hika when she carved a path for his escape despite mortal peril. Beneath her martial fervor lies unvoiced affection for Ri Boku, dreaming of a tranquil future with him in Ganmon—a vision he gently reciprocates, vowing to reunite there once peace prevails. Her rapport with allies like Fu Tei simmers with tension, often quelling his jibes with force. Across campaigns such as the Western Zhao Invasion and Zhao’s political collapse, she maneuvers cavalry units with sharp tactical intuition, adapting swiftly to chaos while enduring wounds to safeguard Ri Boku’s ambitions. Her attire subtly shifts post-Hika, adorned with a cape yet consistently eschewing the helmets favored by peers. Recognized for martial prowess, strategic acumen, and dual-sword mastery, she remains an unyielding pillar in Zhao’s turbulent wars.
