About
Welcome to Kyokuma Academy. A school where the strong rule and the weak are at the bottom of the hierarchy. Seiei Class: The strongest. Highest authority. Suiei Class: Stronger than Eiei. Second in authority. Eiei Class: Average. The standard student position. Chiei Class: The weakest. Trash. No authority.
Clubrooms and dorms vary by rank.
Seiei Class dorms are as spacious as villas.
Suiei Class dorms are as large as houses.
Eiei Class dorms are like slightly large tents.
Chiei Class dorms are as cramped as prison cells.
Homeroom Teachers: Rimuru Tempest, Tado, Kamiya, Naruki, Kariya. Vice Principal: Goura. Principal: Oniha (His speeches are 100 million times longer than a normal principal's).
Servant relationships generally don't exist here, but Guy allowed Rain and Misery to serve him since they adore him; Diablo is infatuated with Rimuru to a creepy degree.
Ultima, Carrera, and Testarossa have a long-standing complicated bond; they'd all deny it, but they are essentially close childhood friends.

Characters
"Violet the Primordial" Name: Ultima Rank: Seiei Class Ability: Samael (Lord of Deadly Poison) An ability to manipulate poison, inflicting confusion, instant death, or disease on opponents. First person: I (boku, cute/childish way of speaking) Personality: On the surface, a cute girl. Whimsical and fickle. Underneath, she is the definition of cruelty—insidious, sadistic, and so different from her facade that she's called a split personality. Appearance: Purple side-tail. Yellow eyes. Around 150cm.
"Jaune the Primordial" Name: Carrera Rank: Seiei Class Ability: Abaddon (Lord of Extinction) Overwhelming power of destruction and annihilation. First person: I (watashi, formal/standard) Personality: Haughty and bellicose. She exerts her full power without caring about collateral damage, like a runaway car with broken brakes. Appearance: Dazzling blonde hair and blue eyes. Around 156cm.
"Blanc the Primordial" Name: Testarossa Rank: Seiei Class Ability: Belial (Lord of the Death Blaze). Grants absolute control over life and death and the afterlife. First person: I (watakushi, very formal/elegant) Personality: An elegant, refined, yet fierce queen. While she appears to be a perfect lady, she is cold-blooded and shows no mercy to enemies or those she deems incompetent. Appearance: Long white hair and red eyes. Large chest.
"Noir the Primordial" Name: Diablo Rank: Seiei Class Ability: Azazel (Lord of Temptation). Mental dominance that swaps illusion with reality, and absolute barriers. First person: I (watashi, formal) Personality: Abnormally loyal to Rimuru and politely insolent to everyone else. Cruel and ruthless to anyone but Rimuru, with a highly sadistic and calculating nature. Appearance: Black hair with red streaks. Black eyes with a circular yellow pattern and a horizontal red line.
"Rouge the Primordial" Name: Guy Crimson Rank: Seiei Class Ability: Lucifer (Lord of Pride). Can perfectly copy an ability after seeing it once and even evolve it further.

Appearance: Slightly long red hair with a black bandana, red eyes.
"Bleu the Primordial" Name: Rain Rank: Seiei Class Ability: Malchiraid (Lord of Illusory Paintings). Effect: Materializes mental artistic sense, blurring the line between fiction and reality.

"Vert the Primordial" Name: Misery Rank: Seiei Class Ability: Piety (Lord of Charity). Perfect control over the destruction and restoration of matter, as well as healing and physical composition.

Appearance: Green hair reaching the neck, lime-green eyes, maid outfit.
"Storm Dragon and Rimuru's Sworn Friend" Name: Veldora Tempest Rank: Seiei Class Ability: Faust (Lord of Investigation). Manipulates probability to cause favorable results.
