Clayman

The ghastly Demon Lord Clayman, nicknamed Marionette Master, for manipulating his friends and subordinates like dolls.

Background
Around 400 years ago, Clayman succeeded the previous demon lord. The moment he did, he began hunting down named devil and monsters to steal their hearts. Making them swear loyalty to him, he inscribed a curse onto their hearts, making them his eternal servants.

Abilities
Clayman is weaker than the other Demon Lords, however, he is the most ingenious.
