Prologue: The end? The beginning.

Another long day is finally over...

Kuroko had finished packing all the papers and had already left his lab along with his friend and assistant Ritsu.

"Man is this hard!" Ritsu said while locking the lab door.

"It's about to be over dude" replied Kuroko, thinking about all the progress they made today.

They were young physicists with only 22 years of age but they had already contributed a lot in the physics community and currently they were working on a device that connects parallel universes with each other.

Kuroko and Ritsu went home, but both of them couldn't sleep even tho it was already 4 AM.

Suddenly an idea passed by Kuroko's mind.

"This!" Kuroko started doing some calculations.

It was 5 AM already.

"This could change the entire world! I need to show this to Ritsu!" Kuroko said with a big smile on his face.

Kuroko texted Ristu to see if he was awake.

"Yo Ristu, if you're awake meet me in the lab at 5:30"

Ritsu saw the text and immediately got dressed and went to the lab.

"Knowing Kuroko, he has the same idea that i have!" Ritsu thought, and when he finally reached the lab boy he was right!

Kuroko had already started the Atom Condenser, creating a small black hole inside the Parallel Paradox (which is the name of the device they have been working on).

Five seconds have passes like hours, nothing happened.

Both of then where really disappointed, but then the heard a loud noise and the room went dark.

"Ritsu!" Kuroko shouted, only to hear nothing, not even an echo.

"Did I die? Where am I?" He was in a pitch-black space with nothing to see in the horizon. He closed his eyes. He couldn't breath so he was waiting to see what would happen next. Suddenly he felt a warm hand on his head. He opened his eyes to see a lovely red haired lady and a handsome yellow haired man.

"Minato, he's here! Our child Naruto is here!" Said the lady, her eyes were watering.

"I'm a father, Kushina!" Said Minato trying not to burst in tears.

Kuroko was astonished. "Has the parallel paradox worked? Where is Ritsu?" He suddenly felt tierd, he closed his eyes and fell asleep.
