Yo Tan Wa rules as king of Qin's Western Mountain Tribes and leads the Confederation of Xirong mountain tribes. Known across the mountains as the "Lord of Death" and revered as queen, she commands absolute loyalty. Her appearance features light-red hair, blue eyes, and traditional facial tattoos: a dot within parentheses on her forehead and two dots beneath each eye. She typically wears robes trimmed with animal furs and an intimidating mask with large fangs and horns covering her face, though she occasionally dons armor unlike most tribesmen. Becoming king of the Chouga tribe young, she conceived the ambition to unite all mountain tribes after elders showed her their territorial domain. During a campaign, she discovered Bajio living as a feral being who acted on instinct and consumed human flesh. Intrigued by his raw strength, she took him under her guidance, helping him adapt to civilization and forging a lasting bond. In 253 BC, she defeated Shunmen of the Bird Fang Tribe in single combat, absorbing his tribe; Shunmen repeatedly challenged her to rematches, losing every encounter. Meeting Ei Sei during the Sei Kyou Rebellion, she initially intended to judge Qin for betraying the mountain tribes centuries prior. Masked and seated on a throne guarded by wolves, she used a distorted voice to conceal her gender. She reconsidered after hearing Ei Sei's proposal to renew their alliance and his vision for unifying China, which aligned with her dream of tribal unity. Shin's impassioned speech about focusing on future dreams rather than past grievances finally convinced her to ally with Qin. She led 3,000 warriors to crush the rebellion, commanding from the front lines while demonstrating exceptional combat skills by effortlessly defeating opponents. Returning to the mountains, she systematically defeated rival tribes, expanding her influence until most mountain lands west of Qin fell under her control. During the Battle of Bayou, she warned Ei Sei about confronting the Xiongnu horsemen tribes threatening Qin's northern borders. Leading 80,000 warriors northward, she discovered a massacred army of 100,000 tribesmen, likely annihilated by Zhao forces, revealing Zhao's hidden military strength and imminent surprise attack on Qin. When the Coalition Army invaded Qin, Yo Tan Wa postponed her campaign against the Kabanko tribe upon receiving Ei Sei's plea for aid. She led 30,000 warriors in a surprise assault on the Zhao army's western front at Sai, overwhelming Commander Fu Tei's forces. Zhao Great General Hou Ken moved to engage her, but Shin intervened to fight him instead. Following the Qin victory, she immediately returned to her mountain campaign. As a Qin general, she captured a Wei city with ease during the Koku You Campaign, later welcoming the Hi Shin Unit. During the Western Zhao Invasion, she served as general of the second army under Supreme Commander Ou Sen. Her forces captured Retsubi fortress effortlessly before engaging in the Battle of Ryouyou. There, she divided her army into three units, using herself as bait to lure Quanrong forces under Rozo and Shun Sui Ju into a trap. After slaying Rozo and capturing Ryouyou, the Quanrong soldiers submitted to her as their new ruler. Appointed one of Qin's new Six Great Generals, she continued fighting on the Zhao frontlines. In the Hango Campaign, she commanded Qin's left wing as Ou Sen's second-in-command. When the Mera Tribe broke through Zhao lines toward Hango, she deployed the Enshu Tribe and Qin Northeastern Army as reinforcements. After the Ou Sen Army's defeat, she orchestrated a full-scale retreat back to Qin territory. Her leadership blends open-minded diplomacy with battlefield ferocity. She negotiated with Ei Sei despite historical tensions but adopts an aggressive, ruthless approach in combat, often charging into battle herself. This duality earns deep respect from her tribesmen, who obey her commands without question. Militarily, she demonstrates tactical intelligence by personally managing both strategy and frontline command. Her physical prowess is formidable: she effortlessly defeated warriors like Shunmen and Goba (elder brother of the Quanrong king) in seconds and knocked out a chieftain with one punch for insubordination. Guidebook stats rate her combat abilities highly, with Strength at 95, Leadership between 99-100, and Intelligence between 95-96. Key relationships include Bajio as her closest friend and subordinate, Tajifu as another loyal commander, and Shunmen as a recurring rival-turned-ally. Heki develops a noted infatuation with her after their first meeting. Historically, the character draws inspiration from the real Qin general Yang Duan He, though the mountain king narrative appears fictionalized. Records indicate Yang Duan He attacked Yan Shi (Wei) in 238 BC and participated in campaigns against Zhao, without mention of mountain tribe leadership. In live-action adaptations, Masami Nagasawa portrays the character across the film series.
