Naruto Shippuden the Movie: The Lost Tower

Naruto Uzumaki is sent on a mission to capture Mukade, a rogue ninja who has disappeared. His pursuit leads him to the ancient ruins of Ouran, a place once known for its historical significance. During the confrontation, Mukade reveals his intention to harness the power of a dormant leyline beneath the ruins. By activating this leyline, Mukade causes a bright light to surround Naruto, which unexpectedly transports him twenty years into the past, before the main events of the series. Upon regaining consciousness, Naruto encounters Minato Namikaze, the Fourth Hokage, marking the beginning of an unexpected alliance.
