Naruto: Naruto started the Fourth Shinobi World War for me

(Partially anthropomorphized, abstract, gravity-based, distorted, dark, and chaotic)
As a transmigrator who has never watched Naruto but has been transported to the world of Naruto, Ningxia, with the tacit approval of the Third Hokage, takes care of a loli known as the Demon Fox.
Ningxia originally only hoped that Naruto could live out the rest of her life peacefully and happily, but when Ningxia realized what was happening, she had already put on Susanoo and Nine-Tails, and announced to the Five Kage that the Fourth Shinobi World War had begun.
And... what do you mean by saying that Madara and Hashirama's battle at the Valley of the End was for me? The masked man wanted to create a world with me in it? Tobirama targeted the Uchiha clan because of me... is that... right?
