The quality of the book and art work in it are indisputable! It is a hardcover edition, and removing the cover sleeve reveals a full-color illustration on the actual book cover. I must warn future buyers that many illustrations inside this book are meant for M (mature) audience and here in America some could be considered as R-rated material. That's not all of the book is about... but a sizeable percentage nevertheless. Most of the book includes funny and daily life illustrations of the characters. Any fan of the Manga or the Anime will be delighted to own this book. Highly recommended!
