Haku Ki Sai was a middle aged man with a clean face. He wore a Wei Army general's armor under a dark cape.
Although he was cowardly natured, Haku Ki Sai was liked by the Wei people. He seemed calm and well aware of his abilities, as he stood in silence while Kai Shi Bou mocked him for running away from the battle field at the sight of Ouki.
He served the Go Kei Army as the 2nd Army General so must of fought along side him for many years earning him the rank go General. He is then promoted to Great General and made the Commander-in-chief of the Wei army during the Sanyou Campaign.
On Qin's offensive against Wei in 245 BC, he was a Vice General in an army led by Great General Go Kei. When Gokei was beaten by Duke Hyou, although he was the only person available to lift morale of the Wei soldiers, in the presence of General Ou Ki he was paralyzed in fear.
During Qin's offensive against Wei in 242 BC, he was acting as Commander-In-Chief of the Wei army, however Ren Pa was the real power behind the army. As the vanguard units battled on the Rui Plains, he noticed that the Qin were gaining the upper hand but Ren Pa calmed him down, saying that the Wei would soon show their true strength.
When Kan Ki managed to sneak into the enemy headquarters, Haku Ki Sai was captured but refused to beg for his life and was immediately slain.
