(2021) Top 10 Strongest Teachers of Babyls Demon School in Iruma-kun Ranked

Teaching kids to count is fine, but teaching them what counts is best- describes some of the qualities of an excellent teacher in our ordinary human world. With that being said, the demon teachers in the prestigious Babyls Demon School are second to none. 

They are fierce nurturers shaping the future of the Netherworld. While some are lenient and cool, others are harsh and strict; however, such a mixed bag is necessary to control the rowdy hormonal demons and uphold the dignity of the academy.

Welcome to Demon School! Iruma-kun is a fantasy-school life-based shonen manga series written and illustrated by Osamu Nishi. It has managed to garner a wide fanbase in such a short period since the release in March 2017. It is based on the life adventures of a 14 year old boy Iruma Suzuki navigating his way through the dark world of the Netherworld.

Since childhood, Iruma had to work hard for the necessities of life due to his good-for-nothing parents, who were always concerned about themselves. One fine day while working a part-time job, suddenly Iruma is kidnapped by a demon and is escorted to the demon world. 

To his surprise, the demon Lord Sullivan offers Iruma to be his grandson. Owing to no choice at all, Iruma agrees and is enrolled in the Babyls Demon School. Thus from here starts his journey in the demon world. Here, we have compiled a list of the Top 10 Strongest Teachers of Babyls Demon School spanning both the anime and manga series.
