Amazing. This extra novel that sheds some light on Felix/Ferris and Crusch's past is better than the main story. BUY IT. READ IT. This book is about Ferris and Crusch, so if you are interested in them, this is a must-read. The events in this book won't be told in the anime unless this novel gets animated at some point. Hopefully it does. It's so good. Even if you are not particularly interested in these characters, still read it. This novel also introduces their childhood friend, who is quite an important and amazing person and has ties to the Kingdom of Lugnica. The light novel art isamazing. The illustrator is really really good.
