King Kei Bin had a long goatee with a long, thin moustache. He is seen with regal court robes.
Kei Bin is unfazed by the situation on the invading Qin force and talks freely with Ren Pa as though they were old friends. He seemed caught up in the enthusiasm of Ren Pa's story of when he faced Ou Ki.
Upon news of the Qin invasion, he states he has no fear as Ren Pa is with him to mete out his justice.
Upon Ren Pa's return to the royal palace after his defeat, he reluctantly exiles the great general from the state of Wei while telling him that removing the death penalty was all he could do. Soon after this, Kei Bin is approached by Zhao Prime Minister Ri Boku to speak of the coalition army.
It is assumed that he has great political power in the state and can make key decisions for his people.
