Another Path: A Parallel Future

A few weeks after defeating Toneri Otsutsuki, Naruto was sent to a confidential S-Rank mission. After more than a year, he was now about to return to Konoha. However, despite the current peace, the threat of Otsutsukis were still lurking around. What if the Otsutsukis started to become active during the 'Blank Period' before Naruto became the Hokage? (Post 'The Last' Movie).
