Summary and Preview
Rantarou, a young boy with glasses and reddish hair, begins to attend Ninjutsu Gakuen (Ninja School). He is determined to become an elite ninja, unlike his father who is a very poor, common ninja. At the school, he makes two good friends, Kirimaru and Shinbei. Kirimaru is obsessed with money, and always has some kind of part-time job. Shinbei, a pudgy boy with a constantly running nose and hair that becomes a lethal weapon, is the son of a very rich family. However, Shinbei is not very bright, and usually misses the point of any conversation.
