A human who can eat a ton and is the only one in the Netherworld. Best friends with Alice Asmodeus and Clara Valac. He's incredibly kind-hearted. His birthday is October 11th!

Iruma Suzuki's best friend. His specialty magic is fire, and his familiar is Vino. By the way, he belongs to a demon clan that governs destruction and virtue. He acts like a gentleman, but if you badmouth or act rude toward Iruma, he gets angry and his language gets a bit rough. He calls Clara 'Stupid Clara.' (Student)

Quiet and turns transparent when he gets nervous. Lately, however, he's started to stand out quite a bit. When he actually starts talking, he talks a lot. (Student)

Energetic and innocent. She often vocalizes sound effects, like 'Gyaoon!' or 'Dobaan!' She uses exclamation points a lot. She's a restless girl who can pull anything she's seen before out of her pockets using her family ability. Because of this, she was often used by others, but recently she became friends with Iruma and the others.

He loves the Demon King and is quite large. He uses words like 'Umu!' (Indeed). He calls Iruma his rival. (Student)

He loves games and thinks of Iruma Suzuki as a younger brother. (Student)

She is charming and beautiful, and the class calls her 'Big Sis.' She's not good at tests and often gets failing marks. She's kind and occasionally hosts girls' nights. (Student)

Be careful when you meet him! You might get something stolen before you even notice! He has a lazy older brother named Marius Phantom (a legendary phantom thief who has never been caught) whom he can't stand up to. He's always thinking about how he wants to look down on his brother. (Student)

A strict teacher who gets angry when things are noisy (but doesn't take it out on people unfairly). Everyone is afraid of him. He has no familiar (he was born with a magical beast called Cerberus, and familiars get scared and run away; by the way, he can summon or dismiss it at will). (Teacher)

Caim Kamui: A pervert who was raised to live as a gentleman (result: failure). (Student) Gaap: A demon (person) who refers to himself as 'sessha' and acts like a samurai. He wants everyone to get along and dreams of making 100 friends. When he draws his sword, it has no blade, but he controls the wind to cut things; he's built for combat. Agares Picero: Loves sleeping and is always looking sleepy on top of a cloud-like demon (Shisho). He's lazy, but has a competitive side...! Allocer Schneider: Has a lion-like face with silver fur. Contrary to his spaced-out look, he's a genius who excels at academics. He's called the 'King of Knowledge' and often speaks in four-character idioms.
