Following their heroic efforts at Walter Park, the students of the misfit class return to Babyls Demon School after their summer vacation. What awaits them is not only adoration and admiration but also the shocking revelation that, in order to stay in the luxurious Royal One classroom, the entire class must be promoted to Dalet rank before entering the second year.

As the Harvest and Music Festivals are right around the corner, there seem to be ample opportunities to rank up. Doing so will not be simple, however, as no class thus far has managed to accomplish such a feat. Hoping to give the misfit class a chance to achieve the improbable, the school appoints special tutors to aid in confronting the challenges that lie ahead.

With his sights set beyond Dalet, Iruma Suzuki decides to take strides toward the goal of ranking up, starting with gaining acknowledgement from his special tutor: the short-tempered and selfish Bachiko Barbatos.

Season 3 of Iruma-kun is great in my opinion! Not the best, by all means, but still going quite well

For those who read my preliminary review, the show starts rather slow, true, but it gradually portraits all the Misfits' quirks and characteristics. The Harvest Festival is akin to a tournament arc you'd see in most shounen anime which almost instantly makes it worthwhile. We get to learn a lot more about the supporting characters as well and even though we're all rooting for Iruma, we start to favour them too.

The Festival is engaging, action-packed and most importantly fun (to keep this spoiler-free) - which, let's ...

Mixed Feelings
Iruma-kun was an anime that worked very well as a wonderful “Saturday Morning Cartoon” type of show. Decent comedy, action, and the lovable characters shaped what were two solid seasons. While this season did have some decent moments, it ultimately got hampered by staying in the same setting for most of the season, surrounding the Harvest Festival, which felt a very long, drawn-out arc. It moves away from the school setting, which was where the charm for me was, and into a competition of sorts between the classes. The season jumps around between characters, and balances development out for them, but it forgets what the ...

"Dear Iruma-kun fans, the lovable human dork is back and better than ever" what I WISH I can tell you. But boy, oh boy, Season 3 is to put it simply: a slogfest.

For the 2nd time in a row, I need not mention that mangaka Osamu Nishi's Mairimashita! Iruma-kun a.k.a Welcome to Demon School! Iruma-kun is a juggernaut of a manga that is and still continues to be seralized weekly in Akita Shoten's Weekly Shonen Champion to high praise and fanfare amongst the hardcore Iruma-kun community since its start in 2017. Along with the anime's debut since Fall 2019 under the likes of Japan's primary ...
