Ninja Handbook 

Ancient Handbook revealing the ways of Ninja's throughout past centuries. Detailing moves and remedies of ancient days, the Handbook is often used as a guide for Ninjas in training. Although the Handbook is considered by some to be a myth, because of a terrible Asian's mistake, 2 white people have learned of its existence. Naturally this sparked interest in the index.
