Ittoki Sakuraba was an ordinary student, until his life was turned upside down! He finds out that he is the 19th heir of the famous Iga Ninjas. The Iga must try to defend what is theirs from the Koga, a rivaling clan seeking to end Ittoki’s life. Ittoki is left with no choice but to become a shinobi that’s strong enough to not only protect himself, but also his village. Now a student at Kokuten Ninja Academy, a high school specializing in shinobi techniques, Ittoki learns the way of the modern-day ninja, equipped with high-tech suits and gadgets. Together with students from other villages, Ittoki clashes with the Koga in an attempt to end the rivalry once and for all.
