In particular, the speedy battles of the ninjas enthralled boys all over Japan and continues to attract many fans to this day. Synopsis Sasuke, who has been practicing the art of "Binjutsu" (the art of splitting oneself into many forms by moving quickly and repeatedly), is challenged to a fight by a skilled young ninja. Sasuke, who is completely unable to stand up to the boy ninja's skillful ninjutsu, uses the alter-ego technique out of sheer frustration, but he is soon discovered. Sasuke, who is completely unable to use his own techniques, finds himself in a desperate situation, but is saved by a group of boys who appear out of nowhere. Meanwhile, while Sasuke is struggling against the boy ninjas, Sasuke's father Oozaru, who is cutting down a tree deep in the mountains, is challenged to a fight by Yagyu Tajima, a vassal of Ieyasu. Oozaru struggles against the Yinryu Ninpo, but manages to escape. Sasuke eventually joins his father and learns that the boys who saved him are his cousins (shadow alter ego).
