Laplace

Laplace (ラプラス) the Wonder Pierrot (享楽の道化), is a powerful and skilled Majin working for the Moderate Harlequin Alliance.

Appearance
Laplace wears eerie-looking mask with an asymmetrical smile decorated with rabbit ears and big jewel in the middle, that made it look like he was sneering at anyone he showed it to. His face is hidden underneath the mask, but his red hair can be visible. Laplace's clothing can be described as stuck out clown-like with its rabble of colors and patterns, which consists of colorful robe tied with a bright long ribbon at the waist, fur on the neck, gloves and pointy boots

Personality
Despite his seemingly laid back attitude, Laplace is actually a strong and cunning individual who cares a lot about his friends.

Background
In his previous life, Laplace was a Chosen Hero by the name of Sarion Grimwald, who was father and husband to Elmesia El-Ru Sarion and Sylvia El-Ru. He set out to slay the Chaos Dragon that drove the elves away from their homeland, but was defeated. On the verge of death, Kagali reached out to him and turned him into a Deathman using the forbidden magic "Birthday". However, in the process, due to Kagali's inexperience, Sarion lost his memories. This event birthed the Wonder Pierrot, Laplace.

Forest Disturbance Arc
He aided Gelmud and Clayman in the creation of an Orc Lord, in hopes of it becoming a Demon Lord that they can control.

At one point, Laplace and Gelmud were confronted by Treyni, but they escaped before she was able to apprehend them. Laplace escaped to Clayman's territory, where they observed the events unfolding at the marshlands through crystal orbs.

The Octagram Soars Brightly Arc
Laplace infiltrated the Western Holy Church to try and find out the secret behind it but ultimately he failed after encountering Roy Valentin and had to run away. He tells this story to a mysterious black haired man and a female elf known as Kagali who is later revealed to be the former Demon Lord Kazalim. After he finishes his story, he asks about what Clayman is doing but neither the mysterious man nor Kagali know.

Later, Laplace tried to sneak inside the Church again but failed like last time. This time he was caught by Hinata Sakaguchi. He ran away but was stopped by Roy Valentin, who was in a weakened state at the time. Roy mocks Laplace and tells him that Clayman died. In response to this, Laplace is angered and murders Roy and all the guards he encountered on the way back.

Saint-Monster Confrontation Arc
After he escaped Holy Empire Ruberios, he tells the mysterious man, Kagali and the other two clowns that Clayman died. Their response to this is accusing Laplace of lying and joking. The mysterious man blames himself for his death but Laplaces comforts him and says that Clayman was too reckless and it cost him his life. In response to this Footman becomes angry at Laplace but Kagali calms him down. After everyone regained their calm attitude, they started discussing what to do next. Kagali tells the others that the base of Clayman fell during a single evening at the hands of a small force sent by Rimuru. This was the final straw that made them realize that they can not do anything else for now.

Majins’ Secret Maneuver Arc
After the mysterious man, who was revealed to be Yuuki Kagurazaka returned from the Tempest Founding Festival, he held a meeting with the clowns. Laplace wondered why Yuuki was frustrated. Yuuki tells how he lost confidence after seeing how powerful Rimuru is and they have to rethink their plans. They decided that the best option would be to stay neutral towards Rimuru. After that, Yuuki gave them the job of handling the delivery of summoned otherworlder children to Leon, to the clowns. A bit of thinking later the clowns realize Leon Cromwell's goal. Yuuki explained his plan to Laplace and others and the meeting ended. They were on the move again.

Abilities
Despite his preference of avoiding direct combat, Laplace is actually the most formidable combatant in the Moderate Harlequin Alliance, possessing both strength and intelligence. He is able to effortlessly kill Roy Valentin (a Demon Lord Seed) in a straight fight, even able to rip out his heart so fast he didn't realize it.

Unique Skills

 * Deceiver: A unique skill which combines illusory magic like Deception, Infiltration, and Concealment, which he can use to deceive his opponents' senses. It also has a "defense mechanism" that allows Laplace to detect magic near him.

Trivia

 * Laplace does not prefer direct combat and uses more sneaky and stealthy tactics, because actual fighting could draw too much unnecessary attention, even if the enemy is much weaker than himself.
 * Being the strongest amongst the Moderate Harlequin Alliance, he doesn't show his strength, because he feels it'll be like bullying Clayman.
 * Laplace appears much later in the Web Novel than in the Light Novel. In the Web Novel, he only appeared during the Tenma Great War Arc, the final arc of the story.
 * Laplace acted like a lackey to Gelmud during his initial appearance, despite the fact that Gelmud's employer (Clayman) views Laplace as an equal.
 * The initial appearance of the group made it look like Laplace was ranked below Clayman due to the latter's status as a Demon Lord.
