1: The initial phase of the novel can be a bit dark. The MC can be called a villain at times and due to his path, his morals will constantly shift, so it's clear that the MC isn't entirely evil, but he's not a saint either.
2: I'll focus on the Chunin Exams in the first phase of the novel, but there's a lot of variation even in this phase and it will continue to vary even more afterward. Please be patient if the initial plot resembles the original.
3: My English isn't perfect, far from it, so I used a translator and edited it myself. While I believe I did a good job, I hope readers can let me know of any spelling errors. Due to the translation, some terms may differ between Portuguese and English, so please let me know if you find any so I can correct them.
That's it, enjoy your reading.
