I believe this book might been aimed for a younger crowd.

Our main lead, Iruma, is given a contract by a demon lord who asks for him to be his grandson. It's a weird stuff, but just strange enough to get me intrigued. Through becoming part of this demon world he has to learn to summon demons, meet new demons who can potentioally be love interest, and even learn to fight and defend himself.

It's just that none of it was very interesting, least for me. I couldn't get attached to any character, Iruma especially, way too much of a people pleaser. I also didn't like the demon world in here, reminded me too much of school, like a Harry Potter demon academy. The art was solid enough though and I think for kids or maybe young teens, this might be a solid choice.

(I was given a ARC by Netgallery in exchange for a fair and honest review.)
