Sarutobi Doji, a boy ninja from Hida Takayama, lives in Akio Maru's house in Tokyo for training. The child, who joined the same Aozora Gakuen baseball club as Aki, became a pitcher and played against rivals such as the genius Tetsuya Taki and the rival from the same town, Tetsumaru Fujikawa, as well as the powerful junior high school baseball club, applying ninjutsu. I will face it with special training and aim for the dream of junior high school baseball, the national tournament at Jingu Stadium. After the second district tournament, a new development with almost renewed regular characters started. Toji returns to his village and teams up with his fellow ninjas to face off against a global underground baseball organization.
