Narrator: Susuki Iruma, age fourteen. One day, he became the gradson of a demon called Sullivan. Sullivan loves to spoil Iruma to bits and is even sending him to school.But there is just one problem...
The school Iruma is attending is the demon school Babyls.
Iruma: I need to make sure they don't find out I'm human... Or I might get eaten!
This is the whole plot that most episodes tell us and in essence the only one we need to live this great adventure together with Iruma.
As a manga reader, I couldn't be more satisfied with this anime adaptation.
With regard to its genre, what can you have a simple view as a slice of life, we can all expect several things: Comedy, some romance, some drama, lucky and unfortunate situations in the style of anime, etc.
Mairimashita! Iruma-kun will give you all this and more, the great development that happens Iruma and the charismatic characters, in his "fantastic" school will make you feel that you are also going to his school.
Below are some points about the technical section that I liked about anime.
Animation: Well ... I do not know much about this, but for me the animation always seems fluid and if any image can be detected "something static", it served to give tension to the situation which I think helps a lot.
Seiyuus (voice actors): This is something that I see that not many people comment, but that I always appreciate a lot when watching an anime. The simple fact that a voice does not work with the personality of a character, in my opinion can ruin it a lot. In this case all voices are very energetic and hard work is noted when it comes to demonstrating emotions or in the most common situations. (Above all Clara, my God! As I love her voice, it's perfect!)
Music: I don't know about y'all, but for me music was always perfect with every situation, especially that tune of funeral organ that always sounded, showing some relationship with the school. (Although sometimes it could be something repetitive)
The characters are very enjoyable to see and it is certain that you will at least get fond of one of them, or maybe the same thing happens to me and you end up hating someone in the depths of your heart.

Personal opinions

The student who liked the suffering.
One of the most anticipated arches that was that of Kirio and could not be more satisfied with the faithful adaptation they made, adding some scenes achieve the goal that we understand the intentions of Kirio and his Odyssey in destroying the school. As well as the determination of Iruma and its growth in the face of such adversities.
And please ... It's not the same to see this:

That this:

Simply I loved it.
Favorite episode: # 8 “Head Over Heels fo Clara”

How do you turn 21 pages of a manga into a 24-minute chapter? Here is the proof, this is my personal opinion but this is one of the chapters that I loved the most. Not only is it true to 100% about the “manga” but it improves it, the fact of connecting Iruma's encounter with Ameri made this episode shine more than not. And if that wasn't enough they put a song like cherry on the cake. And I must admit, my heart raced again.
When I saw this scene one more time.
About the Final episode:

A quiet and fun episode that shows us how Iruma has become accustomed to the Underworld. And at the same time it shows us all the development of Iruma and his long way forward and that he still has to follow. Also with a final scene that would surely make anyone curious.
Conclusion
Mairimashita! Iruma-kun is a good anime with an excellent cast, good animation, good music, excellent development and personality of the characters and a great overdose of madness and fantasy that will always lead us to have the curiosity to know more and more about this world in which Iruma lives, called the "Underworld" and his adventure to become the Demon King.
And as the Opening says…

“We're just getting started!”. Well, this adventure is just beginning and there is still a lot to see about Iruma and his friends. In my case, I am eager to see the second season. Thank you for reading.
