Clayman

Clayman is a self-proclaimed Demon Lord and former member of the Ten Great Demon Lords, known as the Marionette Master. A cunning and manipulative schemer, he orchestrated numerous plots from the shadows, including manipulating Milim Nava (or so he believed) and instigating the Falmuth Kingdom's attack on Tempest. Created by the True Demon Lord Kazalim, Clayman is a puppet-type Majin who uses others as pawns. His overconfidence and underestimation of Rimuru prove to be his downfall when he is decisively defeated at the Walpurgis Council.
