"Marionette Master" Clayman is a self-proclaimed Demon Lord and one of the members of the dissolved group called the Ten Great Demon Lords. He is a ghastly man, infamous for his acts of manipulating his friends and subordinates like dolls.

He is also one of the four members of the Moderate Clown Troupe, called the "Crazy Pierrot," which is the highest-ranking subordinates of Demon Lord Kazaream. Despite that, he is actually the weakest member combat wise.


Clayman has an overall appearance of a scheming wealthy noble, which is a given since he lives in a castle. He has a slim, oblong head with a sharp chin and defined jawlines, having a pair of pointed ears on either side. His eyebrows are so thin that one may sometimes confuse the yellow markings on his forehead as his eyebrows instead.

His getup involves a three-layered tuxedo, having an overall white color scheme.


Clayman is a cunning and manipulative Demon Lord. He prefers to manipulate things in the background rather than get into conflict himself. He specializes in intelligence gathering with the use of his ability in order to perfect his scheme to obtain more power.

Clayman treats his subordinates and those he considers below him very poorly. He would throw away those who are no longer useful to him and force others to submit using his unique skill.

However, Clayman is very gentle and considerate towards those who he considered his friends and comrades such as the Moderate Clown Troupe.

He also respects and follows his superior's order with absolute loyalty.


Clayman was part of the Moderate Clown Troupe as Kazaream's aide, known as The Laughing Clown (Crazy Pierrot).

400 years ago, Kazaream helped him become one of the Ten Great Demon Lords. The moment he became a Demon Lord, he began hunting down Majin and monsters to steal their hearts (literally). Making them swear loyalty to him, he inscribed a curse onto their hearts, making them his eternal servants.

After Kazaream was defeated by Leon, Clayman hadn't received any words from him for about 100 years, but several decades prior, he abruptly contacted him, to revive his spiritual body, which is why Clayman needed to gather power.


Clayman was the true mastermind behind the Orc Disaster incident, hoping to gain a puppet Demon Lord to help give him an edge against other Demon Lord. He plotted together with 3 other Demon Lord, that is Milim Nava, Carrion, and Frey.

After his plan failed, he sent out Myulan in order to spy on the new power rising in The Great Jura Forest.

Clayman started plotting a war between humans and monsters wanting it to result in Tempest's demise, and to collect the souls to awaken him into a True Demon Lord.

Ultimately his plan failed and he tried to hunt Rimuru Tempest down by calling a Walpurgis Banquet, but he instead was killed by Rimuru during the banquet.
