I read the first book (Guardian of the Sacred Spirit) in this series after watching half of the anime with the same name. I really liked that book, but I wasn't sure about this one as I knew nothing about it. I wasn't surprised when I found out that I really liked it though! It was a really fun, fast book to read. The characters and the story where engaging, and as usual Balsa kicked ass and was awesome. If you liked the first one I definitely recommend this one..
