Yagyu Jubei was Japan's greatest swordsman. His skill was legendary; his name was whispered reverently by all the other warriors of Japan. But the one enemy he couldn't conquer was death. Before he died though, there would be a successor, and this deserving person would receive all the power and skill of Yagyu Jubei, along with the Lovely Eyepatch. After 300 years of searching, the disciple has found Jiyu Nanohana, a rather ordinary girl who have just moved to a new town. If going to a new school weren't stressful enough, Jiyu is told that she is heir to the legendary talents of Yagyu Jubei. And she will have to put those talents to good use and stop the assassins of the rival clan!
