Our story opens in Japan's past. On his deathbed, the legendary ninja Yagyu Juubei makes his assistant swear the he will not rest until he finds Juubei's successor. Overcome with emotion, this disciple of one of Japan's great historical legends vows to fulfill his master's dying wish, and immediately wishes that he didn't. For his master has described his successor as "lovely and cute," and.. "bouncy." Is Juubei in his right mind? Cut to the present day. A girl named Jiyuu (nicknamed Juubei by her father) is doing her best to get to her new school, despite the weird antics of her bizarre father. On the way home after a trying day of classroom tomfoolery by her classmates, she bumps into Juubei's disciple, who has been wandering around Japan for over two centuries looking for the chosen one. When he sees this girl, he realizes that his task is at an end. Well, nearly, for he has a hard time convincing her of anything, let alone getting her to wear some dumb heart-shaped eyepatch. But when one of her teachers shows up and tries to kill her, she reluctantly agrees. A magical transformation takes place and she suddenly becomes Juubei-chan, ninja warrior! So now that she's Juubei-chan, of course suddenly people are coming out of the woodwork to try and kill her. But who are they? Are they spirits of long-defeated foes looking for vengeance? Are they mercenaries out for a kill? Or are they just dissatisfied substitute teachers? (Credit to carnage.fanfic.org) <br />
