Shinobi no Ittoki

Ittoki Sakuraba believes he is an ordinary student, even if the constant protection from his mother, uncle, and childhood friend Kousetsu has always seemed excessive. The reason becomes clear when an innocent-looking date turns into an assassination attempt and the people around him reveal themselves as ninjas. His mother finally tells him the truth she kept hidden: Ittoki is the nineteenth heir of the Iga clan.

The rival Koga clan wants him dead, and Ittoki has almost no time to understand the world he was born into. He is sent to a specialized ninja academy, where techniques, alliances, and clan politics become part of his preparation to inherit Iga. But the conflict between the two clans will not wait for him to graduate, forcing a boy who never chose this legacy to decide what kind of leader he wants to become.
