The first chapters were mediocre at best, but that changed over time and the story became better. The detailed explanation improved, and it was very illustrative and easy to read without any plot holes. But... there is one thing that this story lacks, and that's the author's creativity. There were some fillers here and there, but creativity in one's work is still a necessary element. The best part is that the characteristics of several personages in this story are very well portrayed, expecially Killua's.
