Synopsis: After the Summit War, once hailed as one of the Four Emperors of the New World and the world's strongest man, "Edward Newgate," believed that today he would rest in peace at the Marine Headquarters. However, when he opens his eyes, he finds himself in a place called the "Ninja World" and encounters a child named "Naruto." "Gurarararara Kid, do you have parents?" Trembling in the presence of the giant-like Whitebeard, the five-year-old Naruto was scared, "N-No, I'm Uzumaki Naruto, and I... I'm an orphan dattebayo" "Naruto, be my son!" "Huh???" Note: This is a Chinese Translation 鸣人,做我儿子吧
I really like this theory, but I would much more like the MC to be Itachi's father, Sasuke with Mikoto, and that he was Naruto's father with Kushina there are very few theories where the MC has children and well before this he the 3rd world war Shinobi would be good that Itachi was born being the son of the MC
