Honestly, don't look at the score. This is a very good story based on one piece. That's exactly what fanfiction is supposed to show. This is the ONLY story where the hero can fight for dozens of days to determine the winner. The system itself is like a pointer that shows the way to development, but you will have to work a LOT. And if you think of this story as a multiverse, which could be, then it's very cool. Yes, there are disadvantages here, I will not list them, because I liked this story. So read it you will like it, do not pay attention to the bottom comment.
