S1·E129 The Village Hidden in the Leaves

While chasing down Urashiki, Boruto and Sasuke get hit with a strange Otsutsuki weapon. They find themselves in the Hidden Leaf, but years before Boruto was born. Although there's no sign of Urashiki, Sasuke thinks they should proceed carefully. Suddenly, a very young Naruto appears with Jiraiya and the two start questioning the "outsiders."
