The Beginning

In an orphanage, 5-year-old Tasumi Rai was playing on a swing when suddenly, he got a really intense headache, which resulted in him falling off the swing. Rai was alone, so no one helped him. He held his head while twisting in pain on the cold, hard, damp ground.

...

Ken was peacefully eating while watching television when suddenly, everything went dark, and he woke up with an intense headache, one which he had never experienced before.

Ken, who had awoken on the damp and dirty ground, was still in pain. It took 20 minutes for the pain to subside a little.

When the pain was over, he looked up and saw that he was outside. "How did I get outside?" he thought to himself. He looked around a bit more and saw that there was a swing.

"How did I get to a kids' playground?" Ken stood up and thought to himself, "Why is this swing so big? What playground am I even at? This one isn't near me."

Ken raised his head and, on the horizon, he caught sight of two children approaching this play area. He was going to yell for their attention when a second, even worse headache hit him. "Damn it, not again!"

"This headache hurts bad, but it's something I have never experienced before." It's weird; however, what came next was even weirder. Memories that weren't mine emerged. "What! Am I in a different body? This body's name is Tasumi Rai."

"He is 5 years old. His parents died in an attack of some kind. He is an orphan." "What? This can't be real," Ken was sifting through the memories when he found something: shinobi! "Oh... my... god, this isn't real!"

"This kid's parents died in the Nine-Tails attack." Ken now knew he was supposedly in the world of Naruto.

Ken then suddenly felt tired and fainted. When the two kids arrived at Ken's location, they were startled and rushed to his collapsed body. The last thing Ken heard was the hurried screams of those two kids.
