-The ruins of Uzushiogakure-
"Well, I guess this is it, huh?" Naruto said with a sad voice.
"We know it's going to happen someday. It's just a matter of when." Kurama said.
Standing in the ruins of the home of his ancestors. Naruto stood in front of the gate with its doors covered in writing. He wore a dark orange jacket over a black long sleeve shirt. He also wore a modified black anbu pants with multiple pockets and a pair of brown boots. His long bright blond hair is covered by the hood of his jacket.
After the defeat of Kaguya Otsutsuki, a short period of peace has been observed in the Elemental Nations. Countries and Hidden Villages alike are working hand in hand to recover from the disasters caused by the Fourth Great Shinobi War. But of course, it wouldn't last long.
Everybody knew it. It only takes a single spark of human greed and hates to reverse all the progress achieved.
Nobody knew better how fickle human nature is than Naruto Uzumaki Namikaze. The last heir of the Senju and Uzumaki clans from his mother's side, Kushina Uzumaki, and the last heir of the Namikaze clan and member of the Uchiha clan from his father's side, the Yondaime Hokage Minato Namikaze.
As a kid, Naruto has always been the target of hate by the citizens of Konoha due to his unique circumstances. He was chosen as the jinchuuriki of the Kyuubi by his own father after it escaped from its previous vessel, his mother. Naruto was raised ignorant from his own heritage by the order of the Sandaime Hokage, Hiruzen Sarutobi. Naruto became the target of scorn and hatred of the ignorant masses due to him being the prison of the Kyuubi. Only recently has this outlook been changed due to his role in the Fourth Shinobi War and the defeat of Kaguya Otsutsuki.
Tired of the cycle of hatred, Naruto trained hard to overcome the challenges that the path to peace would face. He became the foremost master of Fuinjutsu, acquired the ultimate dojutsu RinneTenseiSharingan, or simply called Shinigan, became the first full sage, and acquired the Takigakure's famed kinjutsu, the Jiongu all after the war. He also set out to allow himself to become the jinchuuriki of the nine bijuu. Shukaku, Matatabi, Isobu, Son Gokū, Kokuō, Saiken, Chōmei, Gyūki, and Kurama. This would ensure that the power of the bijuu wouldn't be abused by any hidden village and would allow some form of freedom to the bijuu due to his modified Death God Seal that allows partial autonomy of the bijuu inside the seal.
An unforeseen side effect of all the power he acquired was that he became essentially immortal. An overreaction to his predicament, he decided to leave the world he has known and live a relatively normal life in another world. He dedicated his knowledge of fuinjutsu and near limitless amount of chakra in his disposal, be created a bridge to another world.
Packing up everything he would need and saying one last goodbye to the only world he has known, the 21-year-old Naruto, the hero of the Elemental Nations, left the world in a flash of light so bright it rivaled the sun, without so much as a goodbye to his friends and families.
-Central Park, New York, USA, 2005-
"That is the worst Hiraishin EVER!" Naruto shouted with a fervor
"Shut up! If it's bad for you, how about for us in here!" Chomei replied with equal enthusiasm.
"I guess its a success since we're not dead" Gyuuki added with mirth
"Kit, we need to get out of here. We may have attracted some unwanted attention with our exit" Kurama advised
"Yeah, yeah. I'm going. Sheesh" Naruto said
Applying suppression seals on his nape to cover his chakra signature, he left the scene in as much speed and stealth he could muster without chakra enhancements. Hiding in the shadows of the trees around him, he noticed there are paths and structures in the forest. On second thought, it's not a forest but a large park.
"Who the hell makes a park the size of Konoha." Naruto thought to himself
It took 10 seconds for him to reach the clearing of the park. Still hiding from the shadows, Naruto took notice of the world he landed on. What he saw awed and surprised him. Buildings higher than the Hokage Monument everywhere, carriages running without horses or ox, bright lights that reach for the sky and people, lots and lots of people. All were looking towards where he came from.
"Holy shit" Isobu drawled out.
"Imagine climbing one of those." Son Goku blurted out.
"You're really just big monkey, aren't you." Kokuo teased.
"We need a base of operations while we figure out how this world works." Saiken said.
"Yeah. Let me try something. I feel we are still not far enough from where we came." Naruto said.
Getting Hiraishin kunai from his pocket, he threw it hard at a 45-degree angle to maximize distance and to miss any buildings in its immediate path. When he felt the kunai stopped, he asked Kurama, "Any people near where that kunai landed?"
"None from what I can tell." Kurama replied.
"Ok, here goes nothing."
With a flash of light, he's gone.
