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.

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 (232/? eps)
Seeing Iruma-kun currently has only positive reviews, I feel it's important to provide a critical perspective for those who may be on the fence about it.

The early chapters of Iruma-kun are outstanding, with a good setting, character development, and wholesome, light-hearted comedy. The story focuses on the main trio, and each arc typically lasts for a satisfying 2-3 chapters. Clara is my favorite character in Iruma-kun. Her portrayal is a unique take on the 'happy-go-lucky' archetype, as the author tries to bring out a more human side of her. She frequently attempts to break free from her character stereotype, and these moments of success are ...
