Query: Not just one hero

Ninjas battling classes death, and a kitten with major boundary issues. This series is a must although if you read the manga the ending will be different to the manga. Good character development in part two. More then one main character. If you haven't read the manga a must but if you have you may want to skip this entire series. The first three parts are good but the fourth is trailing way off the manga and could leave fans of the manga a bad taste in there mouth.
