"Welcome to Demon School! Iruma-kun!" is a series currently being serialized in Weekly Shonen Champion, with the first season of the anime airing in 2019. The second series is scheduled to air from April 2021, and the excitement is building even more. Iruma-kun is set in the demon world, and many powerful characters appear in the story. This time, we've ranked who is the strongest! However, there are also many characters who are likely strong in the story, but whose strength is still unknown, and many of these characters have been excluded.
Iruma-kun's Strongest Character Ranking: #1: Former Demon King Delkira
Topping the list is the previous Demon King Delkira, the absolute ruler of the Demon World. He is one of the most powerful demons in the world, commanding the 13 Crowned Demons. He is undoubtedly the strongest character. However, the position of Demon King is currently vacant, and it is unknown whether he is deceased or missing. Nicknamed the "Demon King of Vanishings," he seems to have been a reckless character who left behind many legends, and his name frequently appears throughout the story. It is unknown whether he will appear in the future, but he is undoubtedly a character central to the story.
Iruma-kun's Strongest Ranking #2: Chairman of the Demon School Babylon, Sullivan
He bought Iruma-kun with money and brought him to the Demon World. He's a grandpa who dotes on Iruma-kun and spoils him because he wanted a grandchild. He serves as the chairman of the Demon School Babylon, and through his connections, he was able to get Iruma-kun into the school. He's not only obsessed with his grandson, but also has a carefree personality, living on a whim and with a sense of humor. However, in reality, he's one of the most powerful people in the Demon World, known as the holder of the 13 Crowns. He's a kind-hearted old man who swears he never kills anyone, but I think he's probably killed one or two people.
Iruma-kun's Strongest Ranking #3: Naberius Kaluego, Homeroom Teacher of the Problem Children Class at Demon School
He's the homeroom teacher of the problem children class. He's arrogant, strict, and sadistic. He's a teacher feared by everyone at Demon School, and his strength makes him one of the most powerful in the school. Despite his caring nature, he often finds himself at the mercy of the carefree and laid-back chairman, and is summoned by Iruma-kun and becomes his familiar. His rank is Keto (8), second only to the chairman, one of the most powerful figures in the demon world.
Iruma-kun's Strongest Ranking: 4th Place: Demon School Phantom Biology Teacher, Balam Shichiro
A teacher in charge of Phantom Biology at the Demon School Babylon. A giant demon who always wears a mask, he is nicknamed the "Guardian Gargoyle." He's fearsome because of his intimidating appearance, but he's actually one of the kindest people at school and one of the few people who knows Iruma-kun's true identity as a human. A former classmate of Karuego, he also has a martial arts-loving side, boasting skills on par with Karuego's. Even Asmodeus and Sabnock combined couldn't even scratch him.
Iruma-kun's Strongest Ranking #5: Sullivan's Chamberlain, Opera
The cat-eared chamberlain who informs Sullivan. Her gender is unknown, and she has a calm, collected personality, a sharp tongue, and is extremely sadistic. She is not shy around Sullivan either. Her rank is unknown, but she is a senior to Karuego and Shichirou, and as she used Karuego as her errand boy, Karuego is not good at opera. She is not usually one to be in the spotlight, but at the amusement park she fights alongside Amelie to defeat a giant monster.
Iruma-kun's Strongest Ranking #6: The Archer Who Never Misses a Shot
A demon dressed in Gothic Lolita fashion, nicknamed the Undead Archer of Despair. He possesses an extremely powerful family ability: he can control a bow that never misses a shot, and can keep firing as long as he concentrates. He becomes Iruma-kun's master and teaches him archery, but at first, he only works him around. However, after meeting Sullivan, whom he respects, he remembers his original purpose and decides to train Iruma-kun.
Iruma-kun's Strongest Ranking #7: Student Council President Azazel Ameri
A talented young woman who serves as the student council president of the demon school, Babylon. She was the first to suspect Iruma-kun of being human and tried to uncover his true identity, but after a series of events, she now has feelings for him. She is the most talented student at the demon school, ranked Vau (6). She is prone to overthinking things and often fails against Iruma-kun, but her family's Romanticista ability, the King of Illusions, is a magical ability that super-strengthens herself through self-suggestion (delusions), giving her the power to take down large magical beasts. However, overuse can backfire.
Iruma-kun's Strongest Character Ranking: #8 - The Kind-Hearted Protagonist, Iruma Suzuki
The unfortunate protagonist was sold to the devil by his worthless parents. Due to his unfortunate circumstances, he had zero attack and maxed out defense, possessing superhuman danger-avoidance abilities. However, he has become stronger thanks to his mastery of Sullivan's magically imbued Ring of Gluttony and the bow magic he learned under Barbatos's guidance. However, his greatest strengths are his boundlessly kind personality, his unwavering mental fortitude, and his unparalleled charisma. Iruma-kun's greatest weapons are his incredibly kind nature, his unwavering mental strength, and his captivating charisma. When his personality is drastically transformed by the Gluttony Ring, he displays his intense charisma.
Iruma-kun's Strongest Ranking #9: Amy Kiriwo, Former Leader of the Magical Tool Research Division
A sickly, bespectacled third-year student who serves as the leader of the Magical Tool Research Division. Although he usually wears a gentle smile, he leads a solitary life due to his low magical powers and frail constitution. He has a kind-hearted personality and hits it off with Iruma-kun, but his true nature is that of a crazy person who gets excited by seeing others twisted in despair. He attempts to carry out the biggest, most devastating incident in the history of Demon Academy by massacring all the students and faculty at the school, but is thwarted and arrested by Iruma-kun. He later escapes with the Rokushishu at his side, becoming the interim final boss. He is a charismatic character who attracts people in a different way to Iruma-kun.
Iruma-kun's Strongest Ranking #10: Iruma-kun's Best Friend, Asmodeus Alice
A handsome young man and a freshman at the Demon School, he initially views Iruma-kun as an enemy, but after losing a duel to him, he becomes infatuated with him. He is an excellent student who excels at everything, and boasts the highest combat abilities in his grade. He is skilled in fire-controlling magic. He usually gives off a calm and collected impression, but his image changes completely when he's around Iruma-kun.
[Welcome to Demon School! Iruma-kun Season 2: Strongest Ranking Summary
We've compiled a current ranking of the strongest characters. However, due to the large number of characters who are talented but only appear by name or in a single scene, this ranking is likely to change. There are also many characters with seemingly limitless talent, such as the 13-crown Devils and the Six Fingers, so the ranking will depend on future developments. Of course, we're looking forward to seeing growth from characters like Iruma-kun and Amy!
