The Novel's Extra: Reader's Chance

I'm doing this fanfic because I want to train my writing, and when I was thinking about what to write I noticed that there are a few TNE fanfics, and I didn't like any of them, not that they're bad, but I didn't like it, because the mcs of them are always overpowers or have powers that don't fit in the world of TNE, I'll try as much as possible to make my fc not break the rules pre-established in the original novel.

English is not my first language so feel free to correct me in the comments.
