Clayman/Relationships

Moderate Harlequin Alliance

 * Kagali
 * Kleiman's master and creator. Kagali was the one who inducted him into the Demon Lord organization 300 years ago by advocating his claim. Even after becoming a Demon Lord, Kleiman still moved following their instructions and still considered himself to be Kazalim's subordinate despite them now technically being equals as Demon Lords. Kazalim saw much of theirself in Kleiman, as he was created by them to be a schemer much like them.


 * After Kazalim's original death to Leon Cromwell's hands, Kleiman took over his territory. Kleiman himself was stated to have never truly considered these territories to be his, but rather Kazalim's and simply took care of them until his master's return.


 * Laplace, Tear, and Footman
 * His friend and workmates, that always help Kleiman with his devious schemes. Being the weakest in Moderate Harlequin Alliance, he tried to gain power in order to be on their level of strength. Laplace, Tear, and Footman are one of the few people that treated good by Kleiman.

Kazalim's Subordinates
As seen in Trinity in Tempest, after Kazalim's death, Kleiman was stated to have been firmly backed by the rest of his master's subordinates in taking over leadership of Jistav and Kazalim's territories. Kazalim's other subordinates in particular greatly respected Kleiman due to his close relationship with Kazalim as his second in command and did not object when he took over and even assisted him in his rise to power and his successful bid to become a officially recognized Demon Lord. Kleiman in turn was implied to care for them greatly and was stated to treat them much better than his other subordinates, as it was implied that he had purposefully placed them in the supply line defense at the back of his army during his attempt at invading Beast Kingdom Eurazania instead of the frontline of the army in order to protect them from harm.

Five Fingers
Kleiman was noted to treat his subordinates, the Five Fingers, as disposable pawns and had little to no qualms with using and forcing them into suicidal attacks and operations as long as it benefited him in the end.


 * Nine-Head Beast
 * The Thumb. A fox spirit captured by Eastern Empire, that was sold to Kleiman, cursed and enslaved to serve as a pet and bodyguard.


 * Adalman
 * The Index Finger, head of defense forces in Kleiman's castle. Kleiman's Curse Magic had greatly boosted his power as a monster, transforming him from a wight into a wight king. Adalman is cursed to follow Kleiman's order and destroy any intruders.


 * Yamza
 * The Middle Finger, the top lieutenant within Kleiman's vanguard. He willingly swore loyalty to Kleiman. Therefore, Kleiman treated him a little better than the rest of his subordinates, not cursing him with a spell to take his heart as a hostage and allowing him a lot of freedom in comparison to his other "Fingers". However, as seen from Yamza's death, Kleiman himself was fully aware of the latter's duplicitous and disloyal attitude when backed into a corner and willingness to betray him to save his own life, as seen where Yamza himself was controlled by Kleiman's skills or magics that forced him to ingest one of Charybdis's cores to kill himself and his enemies when the latter attempted to surrender to Tempest and being defeated.


 * Mjurran
 * The Ring Finger. Replacing her heart with "Marionette's Heart", Kleiman treated Myulan as a disposable pawn that isn't fully under his control and wasn't afraid to mock and blackmail her. She was one of the favorite Kleiman's "toys".


 * Pirone
 * The Pinky Finger. Harpy that acted as the spy and intelligence collector for Kleiman. She was one of the few subordinates that Kleiman thought somewhat decently off, because of her usefulness. She died from the blast of Nuclear Cannon that Diablo deflected in the battle against Razen.

Others

 * Gelmud
 * Gelmud was hired by Kleiman with the intention of using him to create a new Demon Lord. Kleiman needed him to only control the Orc Disaster, though he didn't care for his death. Gelmud was viewed as little more than a disposable pawn.

Octagram

 * Guy Crimson
 * A fellow Demon Lord. Guy Crimson is the one of the oldest and powerful Demon Lords, so Kleiman didn't want to come into conflict, so he was greatly respected. It is speculated that Guy Crimson would become the main antagonistic force in his goal of conquering the World.


 * Milim Nava
 * A fellow Demon Lord. Initially Kleiman seemed to have a  neutral-positive relationship with Milim, treating her cordially and tolerating her childhish attitude. However,  this was only a facade. Kleiman actually never liked Milim and wanted to use her as his pawn for his plans. When she was "mind controlled" by Kleiman, he began to insult and even hit her repeatedly.  Kleiman was under the impression that he was the dominating part. However, it turned out Milim deceived him and gave the impression he could control her. After being confronted with the truth, Kleiman  felt cornered and humilliated realizing he was the one being manipulated.


 * Leon Cromwell
 * A fellow Demon Lord. Likely stemming from Leon having killed his creator and master, Kazearem, Kleiman was noted to send various assassins to try and kill Leon. With Guy Crimson himself noting Kleiman's frequent attempts to have Leon killed. When Kleiman was controlling Milim and possessed her as an "ace in his sleeve", he had planned to obliterate and brutally murder Leon after the Walpurgis.


 * Rimuru Tempest
 * Kleiman saw Rimuru as a disturbance and an annoying factor that disrupted his plans. He looked down on him for being a lowly and mere slime who dare proclaim itself as a Demon Lord and was against it.

Other Demon Lords

 * Carrion
 * Carrion was one of the Demon Lords to rise at around the same time as Kleiman. Together with Carrion and Frey, Kleiman was counted as a one of the youngest Demon Lords and was one of the most active alongside them. Because of this, Kleiman was was shown to work together with him in order to increase their power base, as seen where he worked together with him to create the Orc Lord in order to create and put a Puppet Demon Lord in the Demon Lord Council to increase their collective power over the older generations of Demon Lords. Due to this, it can be guessed that Kleiman had a friendly relationship with Carrion. However, as seen from his scheme to use the souls of the people of Beast Kingdom Eurazania in order to awaken as a Demon Lord and him later "having" Milim destroy the capital and conspiring to kill Carrion and later sending his army to kill the surviving people of Eurazania in order to harvest their souls, it can be guessed that Kleiman never really had a true friendship with Carrion and saw him as nothing more than a means to an end.


 * Frey
 * Frey was one of the Demon Lords to rise at around the same time as Kleiman. Together with Carrion and Frey, Kleiman was counted as a one of the youngest Demon Lords and was one of the most active alongside them. Because of this, Kleiman was was shown to work together with her in order to increase their power base, as seen where they had collaborated to create the Orc Lord in order to create and put a Puppet Demon Lord in the Demon Lord Council to increase their collective power over the older generations of Demon Lords. Kleiman would also "team-up" with Frey in order to deal take "control" of Milim by having her give Milim a magical circlet (Pendent in the Anime) filled with Mind Control Magic. With the latter promising her supreme power over the skies by teaming up together. As seen from his behavior with Frey during the Walpurgis, Kleiman was under the impression that he was the dominant one in their partnership and he could perfectly control Frey. This would later come back to haunt him as Frey revealed her betrayal and true loyalties to Milim, resulting in Kleiman being cornered and humiliated upon realizing that he was the one being manipulated them.
