If anything, I am writing right away. Everything that is described after is nothing more than my subjective opinion about the author's work. Whether to listen to it or not is solely the business of anyone who nevertheless reads my comment, which does not cancel your opportunity to still read the work that became the reason for my answer. I apologize in advance if I failed to adequately limit the emotionality of the answer
With all due respect, but this is very, very difficult to read. Yes, the author admitted that English is not his native language, but this does not change the fact that everything is bad with the text. Direct speech is often not highlighted. The story simply jumps from mentioning one event to another without much detail. And let's not forget about simple spelling, syntax and punctuation errors.
It's worth mentioning separately how everything is fixated on the constant repetition of how the heroes "can overcome absolutely everything together". It gives off the spirit of... well. you know those situations when the heroes win on the strength of friendship where they shouldn't have at all. Of course, there is no such thing in the fic, but the spirit of it is there. Although it all started very interestingly, with this play of contrasts of guilt and "a chance to do everything better", but, as for me, then everything got worse. If you want to see the hero's victory over the world of tough and cruel magi here, then... you will be disappointed. Here everyone understands each other, everyone is ready to unite for the sake of tomorrow. They give all of themselves, all their strength, their knowledge... It is already clear that this is not the world of Nasuverse.
This is a good premise for a story, but oh my God, how much work needs to be done on this in the future.
