great
i can see this developing into a great series. you should make them a bit longer though, at the moment they are too small. some of the characters are really cheesy though, but i guess that kinda helps along with the story.
also, to anyone who cares, ninja's were originally from japan, often peasants, who mastered special martial arts techniques to use against their enemies, who were confused by their unorthodox methods and ingenious stealth devices and weapons.
