I was hesitant to buy this book, thinking it will be just another of those information books(from most series) which touches stuffs you already know. Man, I was wrong. This book is thicker and a bit bigger than the usual Naruto manga. And the information inside are just amazing, it covers everything from Naruto manga #1-43. I will give you guys a short summary of what to expect:
Shinobi Data - shows every character in Naruto, what village they are from, their rank, skills, what significant things they did, etc. Most characters got 2 pages, but some got more.
Jutsu Data - lots of jutsu explained(with art of course).
Illustrations Data - sketches/blueprints of Naruto's creator, as well as a short story only found in this book.
Shinobi Facts - more data about important groups, events.
Naruto Dictionary - as it implies, dictionary of the terms in Naruto, as well as places and the likes.
Character Data - from height comparison to who belongs to which blood type, relationship charts, and more!
Reader Survey - survey from Shonen Jump Weekly, about questions like "who do you want to be a teacher?" to "favorite battles"... Its an interesting fact from other fans!
Konoha Collection - just random info you may or may not know, like how Naruto got his name. This one is scattered throughout the book.
The first few pages by the way is colored, and it says "Naruto Best Scene", I dont know who picked this(maybe Masashi himself), but yes, it shows some of the coolest scenes of the series.
Overall, I didnt regret buying this one bit. Again, I was a bit hesitant at first, but now, I can say it is money well spent. The amount of data here is just staggering, and will really help new fans to catch up(beware of spoilers though), old fans to recap/reminisc their Naruto knowledge, and for the collectors to enjoy. And there is always something new to learn for everyone here, may you be a genin or Hokage! SO GO BUY THIS BOOK! ITS AWESOME! BELIEVE IT!
