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 ...

Marimashita! Iruma-Kun started as a welcome breath of fresh air; the plot, the character designs, the comedic timing, the backgrounds and even the OP looked like taken straight out of a forgotten shounen school comedy from 2002. Like those early noughts series, Marimashita! Iruma-Kun is based on a simple long running gag: Suzuki Iruma is our MC, a human without any sort of magical power who attends a demon school and the only thing he wants is to avoid danger by not standing out. Everything he does to keep his peaceful school life and annonymacy backfires and by the end of every story arc, Iruma ...

Well the synopsis of this anime promised. A boy named Suzuki Iruma is sold by his parents to a demon. Then everything becomes cliche.

The protagonist easily forgets his parents. He is sent to a demonic school where the song itself is supposed to be eating humans. One could be fascinated by how the activities in the demon world will be and how he will survive so that no one discovers that he is human, but what takes away his grace is that they do the same as all humans.

All difficulties are solved with the power of your benefactor. The story behind never progresses. ...
