Moderate Harlequin Alliance

The Moderate Harlequin Alliance is a group of jacks-of-all-trades that can be hired to do various kinds of jobs.

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

Background
They are a group of Deathmen created by Kagali before she ascended as a Demon Lord. Not much else is known about them.

Forest Disturbance Arc
The group was working under Gelmud and was helping in the creation of a puppet Demon Lord.

Demon Lord Attack Arc
Tear managed to gain the info that Demon Lord Frey feared the return of Charybdis, and shared this info with Clayman. Clayman then offered Frey to eliminate the threat in exchange for a favor.

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.

Saint-Monster Confrontation Arc
They were seen mourning the death of Clayman.

Majin Behind The Scenes Arc
Kagali and Yuuki went into the ruins together with Rimuru, Milim, Gobta, Ranga, and Shion, as a trap setup by Mariabell Rosso.

Hero Awakening Arc
Together with Yuuki, they conspired with Granbell Rosso in order to steal Luminous' ultimate weapon. They succeeded in unleashing the "weapon" (which is Chronoa), but realized that they've been tricked by Granbell.

Trivia

 * This group had a much smaller role in the Web Novel compared to the Light Novel. In the Web Novel, other members except Clayman only appeared during the Tenma Great War Arc, the final arc of the story.
 * Given Clayman's transformation, it's possible Laplace, Tear and Footman also have other forms more suited for combat.
 * Ironically, it's the Clowns' schemes that made Rimuru and Jura Tempest Federation a superpower that poses the greatest threat to them, beginning with the Orc Lord's rampage. It's their schemes that forced Rimuru and Co. to seek allies and powerup themselves.
 * 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.
 * The scheme involving the Kingdom of Falmuth resulted in Rimuru awakening as a True Demon Lord.
