Synopsis

Fourteen-year-old Iruma Suzuki has the worst luck possible! Incapable of saying no to anyone, he has always performed whatever life-threatening jobs his greedy and lazy parents requested. His life takes an unexpected turn when they form a contract with Sullivan, a high-ranking demon, at the cost of his soul. Afraid and confused, Iruma is surprised that all Sullivan wants is to act as his grandfather.

Sullivan takes care of Iruma and decides to enroll him in the demon school Babyls. Iruma's greatest challenge is hiding his status as a human, so keeping a low profile among his peers is the only option. However, Iruma will soon discover that he is no ordinary human, and the demons might also be more than what meets the eye.

This is going to be a spoiler free and a short review.

Story:
The story is in my view is unique and interesting. The pacing is without issues in my view and flows really well.

Art:
The art is fine; it is detailed when it needs to be, it is not when it's to make something comedic or to draw attention to. It is endearing and is definitely pleasant to look at.

Character:
This is perhaps my favourite part of Mairimashita! Iruma-kun. I can't seem to help but love every character. When a character is first introduced I didn't tend to like them but that is quickly swept away when ...

The early chapters of Iruma-kun are outstanding, featuring a well-crafted setting, strong character development, and wholesome, light-hearted comedy.

Her attempts to break free from her stereotype and showcase a more human side are some of the manga's highlights.

However, the story takes a sharp turn around chapter 100, with longer arcs, new villains, and an influx of secondary characters. While the classmates outside of the main trio are fairly developed, they pale ...

There are no negative reviews on this series and only 2/17 are mixed feelings, so let me be the first one to recommend SKIPPING this series.

I LOVED this series. Past tense. Now I’m frustrated with where it’s going. I watched the anime when it first came out and I have huge respect for the scanlation team for catching up considering how far behind we were. The official English translation is about 30 volumes behind. I have physical volumes of this series, but quite frankly have become disillusioned with the series as it has gone on.

Iruma-kun has the same problem as One Piece and Detective Conan. ...
