In the ninja world where there are many ninjas, Ryu Kazama, a young man from Shadow Leaf Village, cherishes the dream of "making his family rise". He has the heroine Sakurano Mari and his best friend Retsu Sarumaru by his side. They hilariously and nervously challenged weird exams and encountered various provocations from enemy villages. The three of them accidentally got involved in the world conspiracy designed by the black shadow Qianye, and joined hands to fight against the power struggle between villages and the crisis of mysterious ninjutsu. Humor and passion go hand in hand. They grow together, gain friendship and understanding, and finally uncover the mystery of Qianye's life experience and unite the villages to protect the ninja world. In the ending, Ryuu not only becomes the strongest ninja, but also helps the village revitalize and usher in a new era in the ninja world.
