Naruto Shippûden: The Lost Tower

Our hero Naruto is caught in special chakra that propels him into the past. He finds himself in the City of Loran. As he encounters strange things, can he save the future with the past?
Assigned on a mission to capture Mukade, a missing-nin, Naruto Uzumaki sets out for the once glorious historic ruins of "Ouran", where he pursues and corners the rouge ninja. Mukade's goal is revealed to be a dormant leyline within the ruins; he unleashes the power of the leyline, causing a light to envelop Naruto, sending him into the past, 20 years before the series began. When Naruto awakens, he comes into contact with the Fourth Hokage, Minato Namikaze.
