Unfortunately, from my perspective, it's a little lighter, as several chapters increased to recall fundamental that I know fairly well, so that information that is useful to me is actually quite dispersed. One might then think that this is a manual for beginners. Except I am convinced that it is almost impossible to learn Japanese by following this book, unless perhaps to be a hard student. Lessons are short, it gives ten examples and then presto! passes to the next grammar point. So I do not really know to whom this book is: not for beginners, so it seems to me; not to those who already know understand Japanese manga for sure; finally I am perhaps in the core target, yet I find it too ... scattered.
