Put simply, this guide book should be owned by everyone who's interested in Den'nou Coil series. The series has a lot of characters and complex relationships, both past and present, so having a nice chart describing them is a big plus. A glossary for all the technical terms is a big help, too.
Even beyond the informational usefulness, the book is practically all full color. Illustrations, episode guides, interviews, design sketches, etc., you name it, it's got it. At less than Y2,000, it's the bargain of the century!
