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.

Mixed Feelings
the season lacked content and was childish .but believe me this anime is a REAL GEM.
they are putting very much effort into the manga but the thing is that the anime wont make any impact due to these ABSOLUTE SHI*TY ANIMATIONS that's not suited for this anime.

"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 ...
