Fourteen-year-old Iruma Suzuki has been unfortunate all his life, having to work to earn money for his irresponsible parents despite being underage. One day, he finds out that his parents sold him to the demon Sullivan. However, Iruma's worries about what will become of him are soon relieved, for Sullivan merely wants a grandchild, pampering him and making him attend the demon school Babyls.

At first, Iruma tries to keep a low profile in fear of his peers discovering that he is human. Unfortunately, this ends up being more difficult than he expected. It turns out that Sullivan himself is the chairman of the school, and everyone expects him to become the next Demon King!

Iruma immediately finds himself in an outrageous situation when he has to chant a forbidden spell in front of the entire school. With this, Iruma instantly earns a reputation he does not want. Even so, he is bound to be roped into more bizarre circumstances.

I was unsure, unsure of watching this. I thought it would be so generic and unfunny to roll my eyes. I thought that I'd hate the show and its characters. I thought if I start watching the anime I would have dropped it within the first 5 minutes. I thought of all this and decided to skip it. I decited to not watch it, and I ignored it. I ignored all the memes people were making of the show. I ignored all the videos on Youtube and all the possible outcomes to getting a single picture of the show in front of me. I indeed ...

Sometimes we are tempted to exaggerate about a series. Mairimashita! Iruma-kun will give us that opportunity, but in the end, the series can be considered average. From some perspective, the series is for a demographic group, children, if we look at the character designs, the licensors, the plot all points to that. Despite all those facts, the series can be enjoyable for any group of age. I think that the series succeeded in the comedy execution, it is not the best, but it can bring a smile into our faces.

Mairimashita! Iruma-kun is a very charming anime. It is the kind of anime you start watching to feel relaxed and before you know it, you are invested in it so much you can't wait the week before the next episode comes out. It is that type of anime and I'm so glad I didn't miss out on it.

The plot is very easy to understand, it is about a boy who was sold to a devil by his parents and he has to try his best to hide that he is a human while going to a devil school. One of the things I liked ...
