Naruto: The Hyuga Couple Takes on the Otsutsuki

During the Fourth Shinobi World War, Hinata's Byakugan awakens when Neji is in danger, allowing her to save him. After the war, peace returns, and the Konoha 12 settle into ordinary romantic lives. The Hyuga Clan nearly went extinct because of the incident on the moon. If the Sage of Six Paths could give his descendants a boost, then so can I, Hamura! Neji and Hinata travel to the moon and inherit Hamura's legacy. Starting with the awakening of the Tenseigan, they make the Hyuga great again. From then on, Neji Hyuga, the one who changes fate, and Hinata Hyuga, the Byakugan Princess, reform the Caged Bird Seal, lead change throughout the shinobi world, and guide the Konoha 12 in an all-out assault on the Ōtsutsuki Clan.

(The main pairing is Neji and Hinata; all other canon pairings remain unchanged, and Naruto stays single. If that bothers you, please don't read. I'm sensitive, so please don't be mean.)
