I gave this book to my 16 year old daughter who loved the surprise. She was in heaven and devoured in a few hours ... I personally find that this book is very playful, very colorful, very well illustrated and agfréable in its format and presentation with cards, small pockets for storing the , very concise explanations. But I expected more developed texts, more extensive ... so I would say this is a perfect book for teenager (s) and fans of Japanese manga but not a book to offer an adult. However, do not hesitate for a gift is perfect!
