Isekai genre is kind of getting stupid bloated, and sadly an overwhelming portion of it is what’s come to be known as “power fantasy”, in which the main character, is intentionally made with as little personality as possible, because the writers believe that allows people to mentally “self insert” themselves as the MC.

Which I have to say, most people are considering the genre pretty tired, to the point where many of them are starting with paordies of the genre.
