After Konoha was built and the first Shinobi War was over, Tobirama got drunk and got Izumi Uchiha, the younger sister of Madara Uchiha, pregnant. Izumi raised him for five years until she was killed by Madara Uchiha when he tried to abandon Konoha. Izumi made sure that Tobirama would take care of him, but at the age of 6, Mito Uzumaki and Tobirama made a mistake on a seal and caused Naruto to be sealed in a scroll but Mito and Tobirama thought that they killed him and kept the scroll in the Hokage's office to remember Naruto.
