The Hero Life of a (Self-Proclaimed) "Mediocre" Demon!

Now that he has reached 20 years of age, self-proclaimed mediocre demon Chrono Alkon is eager to begin his mandatory year of schooling in the Demon King’s castle. It’s his dream to spend the year having fun and making friends, but when he gets a shocking result in his class designation test, that dream is put in jeopardy. To make things even more difficult, Chrono is from a small remote village and has little sense of what is considered “normal” at school. As the resident country bumpkin, he finds himself facing maddening misunderstandings and unexpected adventures. Will this “mediocre” demon ever have the peaceful school life he’s always wanted, or will he be derailed by the demons who understand him better than he understands himself?
