Kaiu Zenjubo

Kaiu Zenjubo was a tribal chieftain in the Dawn of the Empire who swore fealty to Kaiu himself and was assigned to fortify Kaiu's personal keep. He instead gathered resources and followers for himself, plotting to assassinate his new Lord. In the First War Against Fu Leng against Fu Leng, Kaiu retreated to his keep and lost more than half his troops defending it, after the castle's front wall collapsed and buried hundreds of men alive. Zenjubo was killed by Nokogiribiki: buried, leaving only his head sticking up. Kaiu threw a bamboo saw nearby, so the former chieftain could kill himself using the saw on his neck.
