History[]
Li Mu and Hai Yin[]
Kaine grew up in the province of Ganmon, located in the northern part of Zhao, a region constantly raided by the Northern Horsemen Tribes. As a child, she witnessed the brutal death of her parents at the hands of the Xiongnu, leaving her orphaned. The generals sent to protect the region consistently failed, often due to their hot-headedness and impatience, which led to their untimely deaths.
However, when Ri Boku, a relatively young and inexperienced general, was appointed to the region, he managed to halt the Xiongnu’s raids by employing a clever strategy—he avoided direct confrontation. Instead of fighting the raiders head-on, Ri Boku trained the villagers to evacuate and take shelter within the walls of Gan Mon Castle during the attacks.
Initially, Kaine and her friend Shou, an archer, were dissatisfied with this strategy. They longed for revenge and wanted to face the Xiongnu directly, believing it to be cowardly to retreat. Kaine, in particular, was driven by a desire for vengeance after the death of her parents. However, she eventually realized that Ri Boku had experienced a similar tragedy. He, too, had been orphaned in a war and lost his brothers and close friends.
Blinded by rage, Ri Boku had once disobeyed orders and charged headlong into battle with his 1000-man battalion. His satisfaction at killing the enemy general turned to regret when he discovered that his reckless actions had led to the annihilation of his entire unit, which had included his family and friends.
Instead of continuing down the path of vengeance, Ri Boku chose to become a Strategist, prioritizing the survival of his comrades over personal revenge. Unaware that Kaine had come to understand his actions, Shou reported to Kantan that Ri Boku was neglecting his duties, leading to his dismissal and replacement by another impulsive commander. The result was disastrous: Gan Mon Castle was overrun, the replacement general was killed, and most of Zhao's forces in the region were wiped out. Refugees were forced to flee south. Afterward, Shou was killed, and Kaine was left among the few survivors.
Kaine, wounded and filled with regret over Ri Boku's exile and its devastating consequences for Gan Mon, buried her fallen comrades. Shortly after, Ri Boku returned, and the two of them, along with the surviving soldiers, rebuilt their forces. With time, they amassed enough skilled fighters to defeat another Xiongnu raiding party. This victory was witnessed by Yo Tan Wa, who saw the aftermath as she set out on her campaign against the Horse Tribes.
During her time in the northern region, Kaine honed her skills in mountain horsemanship and became a capable dual sword wielder. When Ri Boku left to pursue his path in warfare and politics, Kaine followed him, becoming his loyal bodyguard.

At some point, she noticed that Ten was on the walls giving orders and guiding the militia. Instead of killing her, Kaine knocked Ten out and ordered one of her vassals to bring her along as a hostage. Shin, who witnessed the scene, charged at Kaine and knocked her off the walls. Ten grabbed her hand before she could fall and attempted to save her, but Kaine was determined to either take Ten with her or kill her right there.
