20 [Similar Anime] Like Welcome to Demon School! Iruma-kun

A pushover with a bad haircut starts at a school where people have supernatural powers while he technically has none (instead his powers are borrowed). Marimashita Iruma-kun is more lighthearted and cute.

Similar art and colour palette.

Both Iruma-Kun And Hayate no Gotoku! Start very similarly with both the main characters, Iruma and Hayate, Taken away because of their parents. Both main characters have tendencies to put others before themselves. So in my opinion if you like Mairimashita! Iruma-kun you should like Hayate as well

Both are follow the wacky life of human dealing with demons. With characters that are extremely intimidating and or violent but actually nice or silly. There is even a training mantage included. These two are match made in Heaven or should I say Hell.

The main characters both have to hide their true race identity. In Ao no exorcist, Rin has to hide the fact that he is half-demon (son of satan) while being part of an exorcist community, while in Mairimashita! Iruma-kun, Iruma has to hide the fact that he is human in a world of demon.
Nonetheless, both has this school/demon/action/comedy vibe and are very pleasant to watch to relax and distract yourself! Definitely recommend both!!

they're not exactly alike in plot, but the overall feel of the series is quite similar.
they are both loud sparkly colored and lots of dumb yelling, but can get surprisingly dark for something that looks so child friendly. they both have a massive chaotic neutral energy

- In both shows the MC is a human who ends up at an all demon/monster school in a different world cut off from the human world where humans are supposed to be killed on sight.

An unfortunate kid gets thrown into another world (literally or figuratively) where he gains friends and power somehow. These series throw a shounen cloak on what at the bare bones seems like a dark/gritty story and make it fun.

Both Iruma-kun and Rinne are pretty much alike in several aspects. In both series the "other world" is rich in culture and eccentricities. There is no coincidence a narrator will be interrupting the flow to explain certain aspects which are unknown to us, mortals, but ordinary for youkais/demons.
It is indeed a good choice to enter and learn about these new worlds which the authors created, filling the space with a good comedy dose and lovely characters!

Only thing different about Saiki is that he attends a fairly normal school and he is naturally op. If you enjoyed Mairimashita! Iruma-kun for its comedy then Saiki Kusuo no Ψ-nan is definitely perfect for you. There is way less action (and wholesomeness), but the comedy is amazing as well as the cast (the side characters in Saiki Kusuo no Ψ-nan also has very similar personalities to the side characters in Mairimashita! Iruma-kun).

Both involve a school featuring demon like individuals. Though one school is in the human world and the other in the demon world. Also one is obviously more comedic than the other.

-The premise is quite similar
- both have a human protagonist involved with demons
- the ring of Solomon
- the human is somehow special to the demons

In this case the roles are reversed and a demon is sent to the living world this time
The demon tries to assume into the human society like how iruma is assuming into the demon school

Both are about schools featuring super powered individuals. One being superheroes and the other being demons. One is more serious than the other. Also the protagonists of both shows look very similar.

An ordinary boy ends up in the demon world, and ends up as Demon King. And oh becomes good friends with a fire demon who he defeats in a duel. It's also very comedic.

-Both feature protagonists thrust into a world in which they must use their specialized skills from Earth (survival tactics vs book/craft knowledge) to survive
-Both feature somewhat younger child characters as the protagonist
-Both are a little slower paced but give a lot of detail and attention to their respective fantasy worlds
-Both are a little hampered by lower production values, but make up for it in their writing
-Both protagonists have blue hair (almost entirely inconsequential but a little funny nontheless)

MC is being sold to the demons by his/her family. However their fate is not as bad as it might seem.

Both shows to do with school and contain a variety of characters belonging to a specific character trope making the characters interesting and colourful. The main student in both are the tsukkomi (straight man) characters of the anime so both shows have quite fast paced tsukkomi action.
The premise of Mairimashita! Iruma-kun is different than 100% Pascal-sensei in that one consists of a human student living among demons and the other one an alien teacher living among humans.
Iruma-kun is more story driven and Pascal-sensei is more gag-based with episodes split into parts (but still has a bit of a plot behind the scenes) but the main target audience for both anime are children.
If you're looking for something fun and humorous with a lot of tsukkomi action, I highly suggest one and the other.

Based on the feeling this anime has, I was instantly reminded of Majimoji Rurumo. An ordinary (male) main character is suddenly involved with magic. The whole vibe of the anime is very similar to Mairimashita Iruma-kun. Even the way the main character comes to a lot of bittersweet realizations, and how he finds new friends is very similar.

A bunch of sympathetic (yet evil ?) demons worship a human character who has no idea what's going on, but somehow still leads them and being treated as their master/their leader.
