This book was a huge disappointment to me. However, it was mostly due to my own misunderstanding.
It contains minimal art work or coloured pages, and it's mostly in manga format, black and white, and cheap paper quality.
Majority contains text and interviews, so knowing Japanese is more or less a must.

I mistook this book as an artbook due to it being called a "fan book", which usually is packed with lots of colourful art.
Keep this in mind before you purchase this book!
