Chapter 4:

The battle that marked the end of the war was the largest and bloodiest of them all. It was the decisive battle between the Land of Fire and the Land of Lightning, between the Uchiha clan and the Hyuga clan, between the Sharingan and the Byakugan. It was the battle that determined the fate of both countries and both clans. It was the battle that changed the history of the ninja world.

Naruto participated in that battle alongside his father and other members of the Uchiha clan. He was ten years old, but he was already an experienced and respected ninja. He had participated in many other battles and had shown his courage and talent. He had learned to use his Sharingan to its fullest and mastered katonjutsu like no one else. He had developed his own fighting style, combining the Uchiha clan's taijutsu with the Uzumaki clan's ninjutsu. He had created his own techniques, like the Fire Rasengan or the Explosive Shadow Clone. He had gained many allies and enemies, many friends and rivals, many admirers and fears. Naruto was a prodigy, a genius, a monster. But he was also a child, a human, a living being. Naruto had feelings and emotions, dreams and nightmares, memories and secrets. Naruto had a past life that haunted and confused him.

During those four years of war, Naruto had remembered his entire memory. He had remembered everything he had lived in his other life, in his other world. He had remembered how he was born as the son of the Fourth Hokage and the jinchuriki of the Kyubi. How he had grown up as an outcast and an outsider in Konoha. How he had entered the ninja academy and graduated as a genin. How he had been part of Team 7 alongside Sakura, Sasuke, and Kakashi. How he had lived many adventures and missions with them. How he had fought against enemies like Zabuza, Orochimaru, Itachi, or Pain. How he had trained with Jiraiya to master the Kyubi's chakra. How he had met the other jinchuriki and the bijus. How he had faced the Akatsuki organization and its leader, Tobi. How he had discovered the truth about his past and the Fourth Ninja War. How he had fought against Madara, Obito, and Kaguya. How he had saved the world alongside Sasuke. How he had fulfilled his dream of becoming Hokage. How he had formed a family with Hinata and their children, Boruto and Himawari. Naruto had remembered all of that and more. He had remembered a life full of pain and joy, of hate and love, of war and peace. Naruto didn't know how or why he had remembered all of that. He didn't know if it was a blessing or a curse, an opportunity or a punishment, a reality or an illusion. Naruto only knew that life was his. That Naruto was him. And that Naruto was not him.

Naruto felt torn between two worlds, between two lives, between two identities. He didn't know which one was the true one and which one was false. He didn't know which one he belonged to and which one he renounced. He didn't know what he wanted or what he should do. Sometimes he thought that his current life was real and that his past life was just a dream or a hallucination caused by the stress of war or by some enemy genjutsu. Sometimes he thought that he should forget that past life and focus on his current life. That he should be happy with what he had and with who he was. That he should continue being Uchiha Naruto, the patriarch's son, the bearer of the most powerful Sharingan, the Uchiha clan prodigy. But other times, he thought that his past life was real and that his current life was just an illusion or manipulation created by some hidden enemy or some unknown power. Other times, he thought that he should remember that past life and find a way to return to it. That he should reclaim what he had lost and what had been taken from him. That he should continue being Uzumaki Naruto, the Fourth Hokage's son, the Kyubi's jinchuriki, Konoha's hero. Naruto couldn't decide between one life or the other. He couldn't give up either of them or accept either of them. He couldn't ignore either of them or embrace either of them. Naruto lived with that dilemma in his mind, not knowing what to do or what to think about it. Until that battle came.

That battle was the turning point for Naruto. That battle was where everything changed for him. That battle was where he faced off against the Hyuga clan.

The Hyuga clan was the Uchiha clan's direct rival in the Land of Fire. The Hyuga clan also possessed a powerful dojutsu: the Byakugan. The Byakugan allowed them to see through anything, have a 360-degree vision, and even see the vital points of the human body. The Hyuga clan also mastered the art of juken: a taijutsu style that involved striking the vital points with their fingers to block or damage the enemy's chakra flow. The Hyuga clan considered themselves superior to the Uchiha clan for having an older and purer dojutsu than the Sharingan. The Hyuga clan also considered themselves more noble and honorable than the Uchiha clan for having a stricter and more hierarchical family structure that divided the clan into two branches: the main branch and the branch family. The Hyuga clan had a long history of rivalry with the Uchiha clan due to political and ideological issues.
