Chou Keihou is a doushi soldier stationed at the Seiryuukan checkpoint fortress. Alongside Fu Lin, he was dispatched by Bunchuu to hinder Kou Hiko's escape. In the anime, their mission also involved retrieving the two princes, Yinxiao and Yinhong.
He wields the paopei named Koujyu, which resembles a megaphone. This weapon restrains movement by affecting the nervous system through sound waves. However, for it to be effective, Chou Keihou must shout the name of his intended target.
