A few errors here and there but it's ok, there's not a lot of unrealistic things and it even talks a little about theories of the series. The MC is not a guy who, I don't know, creates moons and can destroy everything with one finger. In general it's a good Fanfic, realistic and with potential to improve

great fanfic, slow development Without too many unrealistic things, it could be better to describe characters, like what clothes they are wearing. Also try to improve the sequel a little bit, things happen a little too fast,I liked the little fight you described, you must have a certain affinity in describing fights, the story is also cool, in general it's an average fanfic, which you can have fun. for your first fanfic it's great
