At first, this manga could feel like yet another generic isekai / sword & magic / academy life product made of all the most common tropes bolted together, but at least the recipe is pretty well executed.
The art is good, without excessive amounts of fan service. The plot is decent (I just finished reading chapter 22). And above all, the characters are fun. None of them seems to take themselves seriously. They act like total goofballs and this cracks me up at almost every page.
Not a masterpiece but a solid 8 (maybe a 9). This is exactly what I like to consume for mental relief during these trying times.
