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.

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 ...

Mixed Feelings
Preliminary (333/? eps)
Ok so I began watching Iruma kun as an anime back when it first aired but I then immediately moved onto the manga. I really enjoyed the gang being up to no good and seeing Iruma progress to being the "demon lord" that Sullivan wanted him to be as his "grandson". I really liked a lot of the characters surrounding Iruma like I didnt actually mind at first having a lot of them because they really blended the story well and I always got a chuckle from every chapter as it can be seriously funny. However that all changed recently when the author decides to ...
