Main characters

 * Iruma Suzuki (鈴木入間)
 * Iruma is a 14-year-old human boy who was sold by his parents to the Demon Lord Sullivan, who adopts him as his grandson. Iruma’s parents neglected him (in ridiculously extreme ways), so he was unable to attend normal school regularly in the human world. From a young age, he experienced a variety of situations and had many jobs in order to support himself. These odd experiences helped him develop great adaptability, survival skills and agility.
 * Iruma is also very kind which makes him gullible to requests as he genuinely helps people even at his own inconvenience. He attends the demon school by concealing his true identity as a human. Despite his earnest efforts to keep a low profile, he frequently stands out among his peers partly because of misunderstandings and also from Sullivan's eccentricity. Iruma later learns to come to terms with his popularity; he becomes friends with Alice and Clara and they soon form an unlikely trio. He is highly admired by his fellow classmates and acquaintances.
 * During the Demon Rank placement exams, his rank was immeasurable because the ranking owl gave him the Ring of Gluttony from a Demonic Prophecy instead of a rank badge, so he was placed in the lowest rank: Aleph (Rank 1). Also, Iruma accidentally made his homeroom teacher, Kalego, his familiar. After some initial deliberation, Iruma resolves to work hard to get promoted in rank and to make his new family proud. He wants to protect those he really cares for. He is now currently ranked as He (Rank 5).

He wants to protect those he really cares for. He is now currently ranked as He (Rank 5).


 * Alice Asmodeus (アスモデウス・アリス)
 * Iruma's best friend and loyal companion after he lost a battle to Iruma (who dodged all of his attacks) on his first day at Babyls. Primarily referred to by his family name, or "Azu" for short. His rank and power exceed those of most freshmen, and he has the ability to wield fire. He was the valedictorian of the freshman class, with the highest grades on the entrance exam. At first, he begrudgingly played with Clara upon Iruma's request, but later also becomes her best friend. He is generally very calm, but when Iruma is involved, he becomes more emotional, even fighting with Clara so he can get Iruma's attention. His familiar is a white Gorgon snake who also wields fire. He is now currently ranked as He (Rank 5) as of Volume 25, chapter 266.

 * Ameri Azazel (アザゼル・アメリ)
 * A fox-eared demon who is the president of the student council of the Babyls School for Demons. Although she is dignified and is highly respected by the student population, she is also a girl who is secretly a fan of the human world, especially a romance manga named “First Love Memories”. Ameri was the first demon to suspect that Iruma is a human despite the common belief in Demon World that humans are mythical. She later confirms her suspicions and becomes friends with Iruma and develops strong feelings for him, although Iruma is not aware that she knows he is a human. Her rank is Vau (Rank 6), the highest of any known student.

 * Clara Valac (ウァラク・クララ)
 * A highly odd (even by demon standards) and energetic Valac girl who constantly wants to play. Her bloodline ability allows her to pull out anything she has seen from her pockets, and she had to bribe other demons with snacks to play with her until she met Iruma. Iruma told Clara he doesn't need anything since he truly enjoyed playing with her, which boosts Clara's confidence and she soon becomes best friends with Iruma and Alice. She later also develops feelings for Iruma and vows to make Iruma enchanted by her. Her familiar is a rare indescribable creature called Falfal and she is currently ranked as Daleth (Rank 4)

 * Kalego Naberius (ナベリウス・カルエゴ)
 * Iruma's homeroom teacher. Not knowing Iruma was human when teaching students how to summon familiars, Kalego was summoned by him by accident due to his mark being on the summon sheet. His familiar form is that of a small owl-like creature with bat wings and small black horns. His rank is Cheth (Rank 8), the highest of any demon teacher at the Babyls School for Demons, with the exception of the headmaster, Sullivan, and his friend, Balam Shichirou, who also holds the same rank. Seemingly aloof and skeptic, in reality, he deeply cares for his students and their well-being; though he tends to twist situations so he can punish the Misfit Class for amusement.

 * Sullivan (サリバン)
 * The headmaster of the Babyls School for Demons and a demon who appears as an older man. He is one of the three demons in the Demon World who ranks as a Tet (Rank 9) and is one of the most powerful and influential demons in society. Thus, he is a possible candidate for the new Demon King since the disappearance of the last Demon King. Sullivan is also the demon that buys and subsequently adopts Iruma as his grandson. He did this so he could fill the void he felt every time he went to a meeting with his fellow Tet ranking friends, who said outstanding things about their own grandchildren. Sullivan is also responsible for granting Iruma the ability to read and understand the demon language through magic. He adores his new grandson and showers him with gifts and attention. In an effort to help Iruma blend in, he placed him along with Alice and Clara in the Abnormal Class; under the belief that strange students would camouflage him.

 * Opera (オペラ)
 * Lord Sullivan's assistant, who appears as an androgynous and gender neutral cat-eared demon and also works as a secretary of sorts. Opera lives in the same house as Sullivan and Iruma, and manages the laundry, cooking, timetabling and transport for the two of them. They have a master-servant relationship, with Sullivan relying heavily on Opera's abilities and advice to keep him on track and away from distractions. Opera is one of the few demons that knows Iruma's true identity. Opera's rank is currently unknown, though they might be Cheth (Rank 8). Opera, for some reason, has little to no expression of emotions on their face but rather it shows on Opera’s ears. Humorously, Opera was Kalego's senior during their tenure at Babyls as students and is the only person who Kalego genuinely seems to fear.

During the entrance ceremony, he attacked a teacher believing it would be the quickest way to gain a higher rank, but it was really the quickest way to being in the Abnormal class. He gains respect for Iruma after the Demon Rank placement exams and views him as his rival, although power-wise he clashes with Alice the most. His familiar is a Kelpie and his rank is Daleth (Rank 4).

The anime adaptation was positively received. Reviewing the first episode, Vrai Kaiser praised it for being "a bit of fall sweetness," praising the style, the promise of prominent female characters, hints of a larger plot, heartening that the ending or opening visuals aren't "particularly fanservicey," and the series is building up to "a mostly gender-balanced cast," while saying that it will likely be a "solidly middle-of-the-pack show" but put a smile on their face. When reviewing the first three episodes, Kaiser said that while the series doesn't "have an overabundance of ambition," the stories are executed with "enthusiasm and a kind of energy that...feels accessible to everyone," but praises the series for having writing that doesn't exploit or wallow in "dark machinations behind the scenes," and said that while the series wasn't their favorite for the season, they looked forward to "relaxing with [it] every week," and said they would be sticking with it until the end.
