Kan Ki rose from leading southern Qin's largest bandit gang, the Kan Ki Clan, to become a military commander under General Mou Gou. His bandits transformed into the notorious Kan Ki Army, famed for brutal tactics and psychological warfare. He ascended from vice general to one of Qin's Great Generals and the fifth member of the new generation Six Great Generals. Born among outcasts and orphans, Kan Ki endured systemic oppression and violence. Near death, he was rescued by Shio of the marginalized Saki Clan. Shio's kindness and later murder by rival bandits ignited Kan Ki's enduring rage against societal injustice, cementing his nihilistic belief that states enabled elite exploitation of commoners. He adopted the Saki Clan as family, forging them into warriors for survival. Arrogant, sadistic, and tactically brilliant, Kan Ki displayed a smug demeanor and crude humor, mocking foes and allies alike. His cruelty was extreme: executing surrendered soldiers and civilians without hesitation, employing mutilation and terror tactics like sending bags of eyeballs, and reveling in tormenting defeated enemies. Yet he showed sporadic loyalty, notably to Mou Gou—saluting him and honoring his death with a funeral pyre of enemy captives. He also acknowledged the bravery of the dying general Chou Tou during the Coalition Invasion despite their opposing views. His strategies emphasized unorthodox guerrilla warfare, deception, and high-risk gambles. In the Sanyou Campaign, he infiltrated men disguised as messengers to assassinate Wei strategist Gen Pou, then ambushed commander-in-chief Haku Ki Sai, sawing him in half as retribution. Partnering with Chou Tou in the Coalition Invasion, he eliminated Han commander Sei Kai deep in enemy territory. The Kokuyou Hills campaign showcased his psychological manipulation: massacring civilians from Zhao general Kisui's hometown and displaying their mutilated bodies to shatter enemy morale, securing Qin's control with minimal losses. Kan Ki's most infamous act was the massacre of 100,000 surrendered Zhao soldiers after the Battle of Eikyuu. Qin's leadership criticized this for fueling hatred and undermining unification. King Ei Sei confronted him, warning that repetition meant execution. Kan Ki viewed Qin's unification goal as hypocritical slaughter disguised as peace, benefiting only Qin's citizens. His inner circle, including commanders Rai Do, Koku'Ou, and Ma Ron, shared fierce mutual loyalty. Kan Ki inspired devotion among his outcast soldiers by offering autonomy and plunder. After Rai Do's torture and death by Zhao forces, Kan Ki prioritized vengeance over strategy, leading to his downfall. Encircled by Riboku's army during the Gian Campaign, Kan Ki nearly succeeded in assassinating Riboku, but his blade broke mid-strike. Impaled by multiple spears, he died fighting, upholding his vow to "never return empty-handed." Kan Ki's arc reflects a disillusioned idealist consumed by rage against societal apathy. His backstory hinted at a potential path as a liberator, but Shio's death and the world's indifference steered him toward brutality. Defiant until the end, he yielded nothing in defeat.
