Power of Iruma in Welcome to Demon School! Iruma-kun Explained

When one thinks about demons, two things come to mind their monstrous demonic aura and destructible powers. And there is not an ounce of doubt that the imaginary land of Netherworld created by Osamu Nishi lacks in any of the two. However, due to a glitch in the matrix, an ordinary human is destined to be the Next Demon King and rule over the treacherous world of demons.

Welcome to Demon School! Iruma-kun is a Japanese manga series written and illustrated by Osamu Nishi. Since its release in 2017, it was able to garner an overwhelmingly vast fanbase. In such a short period, it became one of the most successful running manga series of Japan. Owing to its huge success, it was adapted into an anime series that aired in 2019, and currently, season 2 has aired in April 2021.

Welcome to Demon School! Iruma-kun is based on the life adventures of an ordinary 14-year schoolboy- Iruma Suzuki in the Demon-world. For as long as he can remember, Iruma had to work hard to fend for himself, courtesy of his lousy parents. One day while working at one of his many part-time jobs, he was kidnapped by a powerful demon- Lord Sullivan. Scared for his life, Iruma gets a shock of his life when the demon offers Iruma to become his grandchild and stay in the Netherworld.

He is enrolled in the Babyls Demon School and thus, from here starts his adventures in the demon world. Fear-stricken by the fact that he might get eaten if his identity is revealed he tries to maintain a low profile. However, to his dismay his ojisama Lord Sullivan is one of The Great Three (most powerful beings in Netherworld) and also the principal of the school. Hence, attention and criticism follow wherever he goes. With a well-laid plot and exciting characters often ending up in weirdly embarrassing situations this series is a must-read/watch.

By virtue of being a human, Iruma does not possess any demonic powers of his own. He often relies on Sullivan-sama’s magic stored in his ring. Lord Sullivan occupies the second-highest rank of Tet (Rank 9) and is also the most powerful being in the Netherworld; hence, his immense magic stored in the Ring of Gluttony allows Iruma to cast highly powerful spells making him a formidable opponent. He can also call forth his powerful familiar – Naberius Kalego, his very own sensei. Also, learning from his experiences in the Netherworld, Iruma has started to manifest his abilities through training. 

However, there is still a great sense of mystery as to why did Sullivan-sama kidnapped Iruma and why is he going to such great lengths to support him. Maybe his promise to the previous Demon King Delkira to always stay by his side has something to do with it. Since there is a great shroud of mystery around Iruma’s origin, one can never know what kind of ruthless demonic power will Iruma manifests. Here is the list of his powers that are known as of now.

Abilities of Iruma in Welcome to Demon School! Iruma-kun

  • Overwhelming Crisis Evasion Ability: Out of all Iruma’s abilities, this is his ace and the ultimate defense technique. Owing to his rough childhood, Iruma developed an innate ability to avoid danger at any cost. With almost zero reaction time, his body moves involuntarily when sensing danger. Due to this, he was able to dodge Asmodeus’ attacks when they were engaged in a raging battle during the first day of Babyls Demon School. This has saved Iruma from many dangerous situations. This ability can be seen for the first time in Season 1 Episode 1 and after that in the series throughout.
  • Human Blood: Iruma’s blood is a highly precious commodity in the demon world as it has amazing healing abilities and can often make plants grow at monstrous velocity. This ability can be seen for the first time in Season 1, Episode 4, where Iruma healed the child of the Guardian of the Valley with only a single drop of his blood. Also, during the harvest festival (manga chapter 126), he grew the gripping weed to enormous heights using only a single drop of his blood.
  • Ring of Gluttony: While all the students received their ranking badges from the Ranking Owl, Iruma received the golden ring – Ring of Gluttony. The ring contained a demon Alikred which devoured the mana of everyone present there, as seen in Episode 5 Season1. Its hunger was only satisfied by consuming Sullivan-sama’s magic. Iruma could, later on, use this stored magic to cast a powerful spell of his own such as:
  •  Libera – Iruma used this spell to save his school from the sinister plan of Kirio. While chanting this spell, a powerful dragon appeared, which easily broke through Kirio’s barriers which could only be broken by someone of Lord Sullivan’s caliber. (Episode 18, Season 1).
  •  La fire – While using this spell, a powerful purple flame emerges, which devours everything in its path. This was seen for the first time in Episode 6, Season 2, when Iruma burned the trash lined outside the Abnormal Class’ room during his evil cycle.
  • Archery: Before the harvest festival, all the students of the Misfits Class were trained by various teachers to reach the unprecedented Rank 4 Daleth. Iruma was trained by Barbatos Baciko, who discovered his innate talent of archery. After countless efforts, he was able to manifest a bow that even Baciko acknowledged, as seen in manga chapters 99 and 100.
