Moderate Harlequin Alliance

The Moderate Harlequin Alliance are a group of powerful individuals created by Kagali. They are a jack-of-all-trades that can be hired to do various kinds of jobs and their number one and absolute rule is to never betray their friends and clients. Their defining characteristic is their clown-like appearance with use of various masks.

They currently are in the employ of Yuuki Kagurazaka, who is allied with Kagali, the troupe's founder and leader.

Background
Centuries ago, the Ultra-Sorcery Kingdom of the Elves was once prosperous, princess of which was Kagali, but irrational acts of their King who was possessed by Jahil, thus the beautiful nation felt to a young girl who would come to be a demon lord — Milim Nava, the daughter of Star King Dragon Veldanava. On the rubble of kingdom's past glory, the Chaos Dragon appeared and former ruler of Sorcerer's Dynasty Sarion - Sarion Grimwald went to slay him down, but was slain instead. Then, the robed and masked figure approached to the dying Hero who had suffered from Chaos Dragon cursed attacks. Kazalim proposed to Hero, that he can try to resurrect him, but he may lose his memories and will become the puppet of his. Negotiations were concluded. By gathering the grievances of the dead corpses of his homeland and gathering the power of tens of thousands of corpses and unify their power to board the will of a particular individual into the flesh. And as a result of this whim, Sarion Grimwald became undead himself and survived. And that was the moment when "Curse Lord" Kazalim and "Wonder Pierrot" Laplace were born.

After some time the spell was perfected, and Tear, Footman, and Clayman were born. They were lovely, sweet children, naming Kagali. The undead elf created by the birthdays was not ugly at all. Only Kagali had been made ugly on purpose to be so. That hateful father king Jahil had taken away her beauty just to make Kagali suffer. It was too late for her to know that fact. Kagali's appearance was the result of a curse, and there was no way to restore it.

Clayman was created as an experiment to test the theory of the Awakening of Demon Lord Seeds into True Demon Lords. Clayman was Kazalim's most trusted subordinate and even inducted him into the Demon Lord Council many years ago. He was specifically engineered as cunning mastermind, tactical commander and a schemer, similar to himself.

Tear and Footman was created to have formidable combat prowess that could possibly make them a match against a Demon Lord. Even if their intelligence is low, they compensated it with great amounts power that they were gifted by Kagali. Tear does not remember directly her past and describes it as "mixture of memories and feelings", but she actually was the maidservant, in the times when Kagali was a princess. While Footman's backstory is unknown, he, like Tear, was created with heavy amounts of strength and combat for suited for battles.

Footman and Tear incited Phobio to become the host of Charybdis in order to exact revenge against Demon Lord Milim Nava. As a result, Charybdis was eliminated by the combined effort of Rimuru and Milim, and Clayman earned the bargaining chip he desired.

The Octagram Soars Brightly Arc
While Clayman went to the Walpurgis Banquet, Laplace tried to infiltrate the Western Holy Church to try and find out the secret behind it. Footman and Tear helped to observe the war between Clayman's army and Milim's followers against the combined forces of Jura Tempest Federation and Beast Kingdom Eurazania.

Abilities
Every member of Moderate Harlequin Alliance is at least at Demon Lord Seed‘s level in terms of strength. In terms of strength Laplace is leading, while Tear and Footman being not so much behind. Clayman on the other hand is not that powerful comparing to other members in terms of raw physical power, but definitely makes it upas the most educated and dexterous to the plotting and creating various schemes, tactics and strategies.

Trivia

 * Kagali's true biological family was cruel and violent to her, but she didn't gave up and created a new one, which loves her and respects her till this day, that's why Kagali considers Moderate Harlequin Alliance to be her real family even referring to Laplace, Tear, Footman and Clayman as her "children".
 * This group had a much smaller role in the Web Novel compared to the Light Novel. In the Web Novel, it's members except Clayman only appeared during the Tenma Great War Arc, the final arc of the story.

 * The Orc Lord incident led to Rimuru becoming a Demon Lord Seed and the formation of Jura Forest Alliance.
 * The Charybdis incident fostered the bond between Tempest and Carrion.
