PRODUCT: Naruto The Official Fan Book
Well..since anime's such a big part of the Japanese culture, they make fan books for every series. Sometimes I wish they do that here in the States, although not many of the shows are worthy of the effort. So for all the devoted Naruto fans out there, I bring you the Official Naruto Fan Book! The book has a lot of details on the characters and is often referred to as the fan bible. ;)
I think this book is on sale at a number of places. We recommend GKWorld.
