"I was reborn into this world, and I know everything about this world's future because I saw this." After he finished, everyone had a shocked expression on their face.
"What do you mean by saw?" Jiraiya asked,
"Ok, I don't have any memory of my previous life, but I saw you guys in a TV show. I know the story of this world and don't know why I have this memory."
"From when did you have these memories?" Tsunade asked.
"Day I was born." I.e., and then before they say anything, I raise my hand so I can continue. "I didn't tell you guys before because you think I am making the same kind of story now. Also, you think that before you guys say anything, listening to me, I will tell you guys what happened till now since Konohagakure was found by my great-grandfather and Madara Uchiha. After that, I will tell you guys what will happen in the future."
They looked at me and looked at each other; they nodded. "Before that, whatever happens, whatever I do, guys, I am still your son and brother." They looked at me. I continued, "I was afraid you guys would not accept me as your son, so I didn't tell you guys. I was really afraid you would reject me, Mom." Arashi had a sad face and was about to cry.
Tsunade came to him and hugged him. "Whatever happens, you will always be my son. What if you have a memory of your previous life? I don't care. I gave birth to you; you are my son. Don't ever think otherwise." She raised her hand; after seeing her like that, I nodded.
I turned my face towards Jiraiya and Shizune; they both nodded and smiled.
"So tell us about this story. If what you say is true, we can change the future and save some people," Jiraiya said.
So I started first with Kaguya coming to the world and having two children. How her own children sealed her and the Sage of Six Paths' children's names are Indra and Asura. How they fought and about tailed beasts from there, I came to there. Reincarnated as Hashirama and Madara, their friendship and fight and the formation of Konoha, then Madara Uchiha's betrayal and the fight's creation of the Valley of the End, Tobirama becoming Hokage and his death, Hiruzan Sarutobi becoming 3rd Hokage and his 3 students, how they became legendary sannins, and Orochimaru's betrayal and his curse marks, then Jiraiya taking Minato Namikaze as his student and how he got the name 'Yellow Flash of Leaf' and Tsunade's loss in the Third Great Ninja War about Dan and Nawaki, their death, finally Minato Namikaze's death, and sealing the nine tails in his own son .
After hearing this, Jiraiya opened and closed his mouth, not knowing what to say, the same can be said for Tsunade and Shizune.
Finally, Jiraiya finding his voice: "Ok, whatever you told us till now is the same as the things only the top people of the village know, not to mention the Nine Tails attack. You are telling exactly what happened." He looked at Tsunade and said, "She also doesn't know about the same details, so I believe you." After saying that, he nodded at me.
Tsunade is looking at me with concern. "You could have told us, you know."
"I was afraid you wouldn't believe me."
"Why are you afraid? Whatever you told us, we could have talked about ," looking at Jiraiya. "I would have called him soon."
Guilt flashed on her her face; she saw that and continued, "It's ok now that you're telling us, and don't ever think that I don't believe my own son." That last sentence she said angrily.
"I am sorry, really, I was afraid."
"You shouldn't, whatever happens. I believe in you, Arashi," Shizune said.
"Thank you, big sis."
"So about this, whatever you told us about the past, some of the things are news to me," Jiraiya said, and looking at me, he said, "The same thing only we know, and I training students in the same is only known by three people, except me, so I believe you." Jiraiya said
"And please tell us about the future of the Leaf and Ninja world," Jiraiya asked. I looked at my mother and sister; they both nodded, so I started.
Starting with the birth of Naruto, then his treatment in Konoha and who attacked him on his birth, how he extracted nine tails from Kushina Uzumaki, how he attacked, the Uchiha massacre, why it happened, and who did it, who ordered the massacre, then I started to tell them. Arc by arc, the wave ark, the Chunin exam, Orochimaru's attack and killing the third Hokage, Tsunade becoming Hokage, Sasuke leaving Konoha and fighting, and Jiraiya taking Naruto for a training trip.
Then I stopped telling them about Akatsuki and its members. After three years, Jiraiya and Naruto came back from training, Garaa's rescue mission, Asuma's death and revenge , Jiraiya's death in Ame, and Pain attacking Konoha. Naruto defeating Pain with Sage Mode, Sasuke killing Orochimaru and Itachi Uchiha, Danzo becoming the Sixth Hokage, the Five Kage Summit, Sasuke killing Danzo, the Fourth Great Ninja War, Madara coming back with reanimation jutsu, the fight with Madara, the Ten Tails' entry into the battlefield, the previous Hokages' entry into the battlefield, Naruto's control over the Nine Tails, Madara's betrayal of Obito, Black Zetsu's betrayal of Madara, Naruto and Sasuke receiving Sage of the Six Paths power, Kaguya's revival, and how Team 7 sealed Kaguya back
After finishing the story, everyone had different expressions, so I waited silently for their questions.
