Primordial

Primordials (原初の悪魔) also known as Progenitors or Primals, are the oldest and most extraordinarily powerful Daemons. According to Leon Cromwell, each of them is referred to by their signature colors, as a replacement of an actual name.

These "substitute names" don't count as their actual names in the true sense of being a named monster:
 * Purple Primordial Violet (Ultima)
 * White Primordial Blanc (Testarossa)
 * Yellow Primordial Jaune (Carrera)
 * Black Primordial Noir (Diablo)
 * Green Primordial Vert (Mizari)
 * Blue Primordial Bleu (Rhein)
 * Red Primordial Rouge (Guy Crimson)

Appearance
Black: Wears a full butler attire with white gloves. He has black hair with a strand of red in the front.

White: Has silver hair, snow-white skin, and red eyes. She is very beautiful.

Red: Has crimson red hair and is very beautiful.

Personality
According to Leon Cromwell, they are heretical and often troublesome because they fight using technique and wits instead of raw and sheer power, unlike usual Daemons.

Story
Rouge was summoned by a weak-willed human to destroy an opposing country. He carried out the summons contract but also chose to destroy the country of the one who summoned him. He summoned two Daemons, who were also Primordials, Vert and Bleu, to assist his rampage and destroy the country. The screams of terror of those he killed caused Rouge to gain the name Guy, pronounced as "Gii." Due to the numbers killed, and the souls he obtained in the process he satisfied the requirements to become a True True Demon Lord. Later he named Vert as Mizari and Bleu as Rhein.

Noir was summoned by a woman, one of two members of Silver Wings, who begged him to take revenge on the Arch Daemon Orthos. Noir agreed to her wish, and in exchange, devoured her and her companion's Souls. Noir then hunted down Orthos, fulfilling his contract. In the process of doing that, he met Shizue Izawa and took note of her Anti-Magic Mask that not only blocked one of his attacks but also ended up erasing one of his arms instead. The mask made him very intrigued, so after the incident, he secretly continued observing Shizue until the mask lost it's Space-Time attribute when the mask reached Rimuru. Ever since he tried intercepting any Daemon summoning spell performed by Rimuru to get summoned, but the first time Rimuru used it, Noir got one-upped by Beretta instead. But upon Rimuru's second use of Daemon summoning, Noir, as well as two Greater Daemon aides successfully managed to be summoned by Rimuru. Shortly afterwards, Rimuru granted Noir the name "Diablo."

Blanc was the Daemon of note in the Lake Shore Dyed Scarlet Incident. She possessed a young woman by the name of Blanche whom she befriended. Her kingdom had a pact with the Primordial Daemon to one day sacrifice the princess' body to the Daemon as a physical body as long as she kept them safe from other warring nations. This pact was cemented by the crimson eyes of every woman born to the royal family. When the country was destroyed due to schemes of several traitors and the Eastern Empire, Blanche chose to kill herself, which gave Blanc the possession of her body and ownership of her Soul. Blanc then took revenge for her friend causing what would later be known as the "Lake Shore Dyed Scarlet Incident." Then, after many years passed, Diablo persuaded her to meet Rimuru alongside Jaune and Violet. After meeting Rimuru for the first time, she chose to join Tempest and was granted the name "Testarossa" by Rimuru.

Violet was a primordial about whom not much was known, but she seemed to have troubled Luminous a lot. At some point, Diablo persuaded her to meet Rimuru alongside Blanc and Jaune. After meeting Rimuru for the first time, she chose to join Tempest and was granted the name "Ultima" by Rimuru.

Jaune was a primordial about whom not much was known, but she seemed to have troubled Leon a lot. At some point, Diablo persuaded her to meet Rimuru alongside Violet and Blanc. After meeting Rimuru for the first time, she chose to join Tempest and was granted the name "Carrera" by Rimuru.

Abilities
