Shinobi no Ittoki

Ittoki Sakuraba was an ordinary student, until his life was turned upside down! He discovers that he is the 19th heir to the famous Iga ninja clan. The Iga must try to defend what belongs to them against the Koga, a rival clan seeking to end Ittoki's life. He has no choice but to become a shinobi strong enough to 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 ninja, equipped with high-tech suits and gadgets. With other students, Ittoki confronts the Koga with the goal of ending this rivalry once and for all.
