Naruto: It All Began When I Became Uchiha Hikari’s Little Sister

This isn’t an invincible-protagonist story. If you’re looking for mindless wish fulfillment, this isn’t for you. Uchiha Xiangxing, the biological younger sister of Uchiha Hikari, was born during the Warring States period. (Author’s note: the two were born in the same era as Hashirama and Madara.) When her sister was taken by the clan to the western front as a weapon of war because of her dōjutsu, Yachihoko, Xiangxing awakened the Mangekyō Sharingan. Her own dōjutsu, “Ijin,” lets her see a few seconds into the future. The story’s power levels will be fairly balanced, and the protagonist’s dōjutsu will have limitations.

One more thing: later in the story, Uchiha Hikari may end up with Boruto, but that’ll depend on your feedback and whether you want them paired up. The early and middle parts will mainly cover the Warring States period and the Shippuden era, since the author hasn’t watched Boruto: Naruto Next Generations.
