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.

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

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.

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 read more

I thought I'd write a new review for this manga, since an anime adaption is on the way, and the other reviews are a few years old. I'll begin with a short spoiler-free summary, and then move into a deeper review.

Mairimashita Iruma-kun! is a fun school-life style comedy. The art style is somewhat simplistic, the comedy lighthearted and innocent, and the characters are bold and likable. The story is comprised of short arcs, episodic in nature, and there is little to no overarching plot. Characters still maintain the development they received during said arcs, however, so all good. Recommend for a light read, lots of read more

Started reading this one a whim the other day since it doesn't have many chapters so far. Demons and stuff aren't typically my thing, so I didn't expect for it to really catch a hold of me, but I was very pleasantly surprised. The artwork seems a little sloppy an clunky at times, aside form more detailed panels, but it's not really a problem since in a way that just adds to its charm. The characters are super creative, fun and easy to like, even the ones that are supposed to be the "bad guys." The humor is well-timed and genuinely funny. There's no lack read more

The story depicts the original and unique plot . A human boy who was unlucky sold to a old Demon Sullivan. It is very fun to read and interesting to repeat again.

Every chapters day by day gives a hype and excitement that probably one of the good traits of this manga. Even though, the characters potrayed are very not good at all yet the author shows a lot of funny reactions and jokes that slightly find in other mangas.

Nothing can be done, a first human who settled in the Demon World. The first human who gets a first servant who is the number 1 read more
