This is a spoiler free review for the whole series as I don't like rating individual volumes and would rather rate the series as a whole. 

I decided to read this series as an adult as the anime was a big piece of childhood nostalgia for me. I had a great time reading it and remembering bits and pieces from when I was younger. I think it's a really fun series with some strong themes and an amazing art style. I don't think it hit as hard as it did when I was younger, and honestly I found some parts confusing, but I'm really glad I read it.
