Shinobi no Ittoki

忍の一時

Ittoki Sakuraba is an ordinary high-schooler until an assassination attempt reveals he is the heir to the Iga ninja clan. His mother enrolls him at Ninjutsu Gakuen, Japan's only national ninja academy, to train among classmates while the clan hunts whoever wants him dead. As Ittoki takes up the role of the Iga's nineteenth head, the long feud with the rival Koga clan closes in around the school.
