Disclaimer: Naruto x A Great MANY Possible Series - I own none of them.
Story Start!

A very nice apartment.

1 Bedroom, 2 Bathrooms, a Kitchen, a Living Room, a Work Out Room and a Storage closet. It was well sized, and contained very nice furniture overall. In the bedroom at the moment though was a sleeping teenage boy, about 16 years old in age.

He was sleeping comfortably.

"Uzumaki Naruto... Sir... You have been comfortably asleep for quite awhile, I think you should wake up."

Standing next to his bed was a short... humanoid, non-human who stood about 4 feet in height. The humanoid wore a silver body suit with orange markings on it, an orange spiral on the chest. The only hair the creature had was a single patch of beard on it's chin, and 2 small patches of hair on it's upper lip. It's eyes were a uniform black color, no white at all to them, and very glossy.

"In a... huh... EH!?"

Naruto woke up slightly, realized somebody was talking to him... and then he saw that he was not in his own apartment. He jumped out of the bed and reached for a hidden weapon, only to not find it as he looked around and just looked at all of his surroundings. He spotted the Green Humanoid creature that was standing next to the bed with a plate filled with food.

"Sir, please don't freak out. My name is... well my name can't be pronounced in your Native Tongue... You may call me Gree." Gree introduced himself. Naruto just stared at him, stared down at him because of the massive difference in their heights. Naruto was only 5'6" in height, though he was a teenager with room to grow. The difference between that and 4 feet tall was... very noticable, and the stark difference between all of their looks was... obvious.

"AH... I'm dreaming... sup Gree, little alien guy." Naruto accepted the glass of water Gree handed him, and started to eat the simple breakfast.

-10 Minutes Later-

"Woah, nice view." Naruto looked out of the window of the apartment.

They seemed to be on the 200th or higher floor of this apartment, because it was a massive distance to the ground. The entire city was glorious to look at, there was no a single star in the sky, but all of the lights in the city below were amazing to look at.

"Yes, my planet is located in the gap between universes, it exists at the edge of space and time. Thanks to that, we are able to observe many other universes, and learn the best technologies from them. My species society has witnessed a great many worlds and civilizations rise and fall." Gree gave him a very brief history of why the technology in the city was so amazing. There were flying cars for example. "Why, even this very suit I wear is a Gravity Suit. It allows us to adjust our bodies to the gravity of any planet we decide to visit."

"... Hmmm... I do feel a little lighter here."

"Gravity on this world is about 60% as strong as gravity on your own world. The difference might not be noticable for you, but for one with a head as big as mine, the difference is... painful." Gree could see that Naruto still assumed that he was still dreaming.

"So why bring me here?"

"Because, I wish to help you, if you are willing to put in some work." Gree was not sure how to approach this topic well.

He did not know how Naruto would react.

"Hmmm?"

"Time does not flow quite properly here, thanks to that we can send you to any point of time you wish when you return to your own universe. The medicine and healthcare of my world is so advanced, you will not even age while you stay here. You can achieve much training in my world, and then go back in time in your own world." Gree stated how he could help Naruto first. Even if Naruto thought he was dreaming, the idea that he could get tons of training done, and then go back in time was a very intriquing one.

"How much training?" Naruto asked.

"You could get hundreds of years of training, not age a day... and then go back to your world. You could become strong enough to save your parents from their fate, and easily strong enough to become Hokage and save Sasuke." Gree and Naruto were walking down the street.

Naruto saw hundreds of aliens just like Gree.

Almost none of them were wearing Gravity suits though, since Gree had not changed his clothes to his normal attire yet. Instead, all of the aliens were wearing a WIDE variety of clothes that looked like they just came from different places. The funny thing was that seemed to be the only way to tell them apart from each other, other than females not having facial hair, and males styling their facial hair differently.

Gree noticed Naruto saw that.

"My species not does actually have the male and female genders... we are actually, by nature, hermaphrodites, though our genitals are... not quite visible, and we have no secondary sex traits. It is very weird... we learned how strange our species is, by observing humanoid species from across the universes... many of us now wear the clothes and identify as the gender of the humanoid we enjoy watching the most." Gree explained with a hint of pride. "... My favorite color is orange, and I am very fond of track suits myself." Gree glanced towards Naruto with his eyes showing a sparkle of emotion.

"Oh cool." Naruto was still looking around. "So... where can I do the training?"

"In time... In time friend. There are conditions to the training are rather strict. For starters, while you can train for as many years as you want... you are limited on the days here you can train. You can't train the day before, during, or after you compete in a competition." Gree dropped a little info that Naruto picked up.

"Eh... competition?"

"Why, yes. A competition, nothing dangerous, something quite pleasurable actually."

"Pleasurable... is this a perverted competition?" Naruto deadpanned with red cheeks, when he realized that just from the word pleasurable. "... sorry, but... I'm not... interested in any of you little guys." Naruto looked at all of the green people around him, and he didn't imagine himself being attracted to any of them at any time.

No amount of training reward would get his dick hard for them.

"Oh, my species does not compete. Actually, due to no longer aging, and no longer dying... my species has long since lost our real desire to reproduce. Instead, we take humanoids from other universes, and have them compete against each other for our great amusement... you see... it is a bit of a fetish of ours, we enjoy watching our favorites go at it with each other." Gree's face turned slightly brown around his cheeks. It would seem that was his version of a blush, and he couldn't look Naruto in the face when he said it.

"You're perverts."

"Yes."

"You want me to compete in a perverted competition?" Naruto asked, just to make sure.

"As a child, you invented the Sexy Jutsu... the Harem Jutsu... and you are in the process of mastering the Reverse Harem Jutsu... you are quite creative and seductive, though your Libido Levels are quite low, and you are still a virgin... I expect with experience, you could gain great results in contests. You are very attractive as well, and you are... quite popular here, you have no small amount of fans who had watched your universe." Gree explained why he believed Naruto was fit for the competition.

"Libido Levels." Naruto locked in on that.

"As your friend... teammate... Sai once told you. While you do have a penis, it isn't that impressive. That is all, but with your creativity-"

"I'm not small!"

"Correct, you are indeed not small. You are on the lower end of the average, but you still are in the Average size range. With your levels of creativity though I believe once you have experience, you will manage to reach Superstar Status in competitions." Gree confirmed that Naruto wasn't small.

Average wasn't exactly a compliment, but when compared to being called small, it was enough to quell Naruto's anger over Sai's insult being brought up. His cheeks were still red though, and he was very much still irritated about it.

Gree noticed.

"Superstar Status huh... and... The Training?" Naruto asked Gree.

The Training and Time Traveling back to his Own Universe was MUCH more important of a topic for discussion to him than the Sex stuff was. His goals relied on him achieving better results in training than sex.

"Yes, of course..."

-5 Hours Later-

The Training Facility was huge.

"In the back we have Special Gravity Chambers that can go up to 1,000 times... well... the average planets gravity levels. We have coaches here as well, the coaches here don't compete in sex competitions." Gree explained.

Tons of humans were using the training hall.

Work out equipment, artificial waterfalls to train under, and robotic sparring partners as well. Naruto followed Gree and saw very few of his species, and instead tons of humans and similar humanoids training.

They all had a tattoo on the underside of one of their arms.

It was a Black Heart with 3 thick black lines underneath it.

"What are those?" Naruto asked, and Gree looked to where he was looking.

"Those are Combat Marks, those who compete in competitions have them. During a battle, when you climax the black lines will turn pink. The goal is to turn your opponents Heart Pink. The marks only change color during Official Matches. They are painless to apply, and can be removed just as painlessly." Gree knew quite a few humans didn't enjoy pain.

Naruto looked around the training facility some more.

"... Is there any other benefits?"

"When a Champion is brought from their Universe, the act splits their timeline..." Gree could see that Naruto didn't understand him. "... Like a river, breaking off into smaller rivers. When I brought you here, I created a timeline in your Universe where I did bring you here, and where I didn't bring you here... and when you go back to your Universe it will create a 3rd timeline." Gree dumbed it down a bit.

"... OH! That means I can watch myself, and learn techniques that I learn in the future!" Naruto realized that he could see his own timeline from this universe, and he could get inspired by himself. He could learn his own future techniques that he didn't know yet, and use the years of training he could get in this universe to learn and master his own techniques. "Is that against the rules?" Naruto asked.

Gree shook his head.

"Feel free, since what happens to your Universe will split the timeline, and not destroy it, there are no rules against it. We just ask that you not become obsessed with viewing your own universe. Many people who view their own universes become... very distraught if they accidentally see how they die." Gree had seen many champions in the past who accidentally witnessed their own deaths, and became unwilling to go back to their own universes. They also lost the will to compete, and instead ended up becoming a Trainer, a Coach, or a Manager for the competitions.

Naruto weighed everything.

'... So if I compete in these Sex Competitions, I can get access to these training grounds... and I can watch my own universe to get ideas for getting stronger... and I can see who my parents are too.' Naruto realized that as well. If he could see his own past, he could see who his parents were. There was a lot to gain from this. "How do you guys benefit again?" Naruto asked.

"Watching humanoids of other species have sex is a sport for us... similar to how you humans enjoy watching humans play sports for amusement. Sex Games for us are our version of the NBA and Football..."

"Huh?"

"... A different universes sports." Gree realized that he used a sports system from a universe that was not Naruto's universe.

-The Next Day-

Naruto stood in his apartment.

He looked at his right arm, which had the same tattoo as the other people who competed in the competitions. He didn't know what the sport was actually called, but the benefits of the training far outweighed his own embarassment over the idea of it. The TV in the living room was currently playing video from his own Universe... the Timeline of the Universe where he was not brought here. He was watching himself in his universe.

Naruto had a small card in his hand.

Name: Uzumaki Naruto - Sex: Male
Rank: C - Wins/Loss/Draw: 0/0/0
Libido Level: 230 - Virginity Status: (Virgin)

It was his player card, that would automatically update.

EX - Great Superstar
S - Superstar
A - Elite
B - Talented
C - Average (High)
D - Average (Low)
E - Loser

Him being a pervert who invented several perverted techniques, and was trained in seduction techniques apparently brought him to the Upper End of the Average scale when Gree had him scanned for his Player Card.

".. It would be better to start off in Loser rank and get some wins... that way I can see how this system works... guess my life has never been that easy." Naruto sighed and leaned back. It would be a challenge to go up against experienced opponents. '... Apparently Winning and Losing doesn't actually matter, all that matters is that the audience enjoys the match... still... this is for the training.' Naruto stared at his arm again.

Gree entered the room.

"Sir, you should get some sleep. Tomorrow we're going to find you a Coach. Your Debut match will be in a month, opponent undecided for the moment." Gree explained.

"Coach?" Naruto asked.

"Yes, somebody who will help you rise through the ranks. Without a Coach, you will have a lot of trouble in the Upper Leagues. Nobody has ever reached A rank without a Coach to assist them." Gree wanted to stress how important it was for Naruto to get a Coach.

Naruto listened.

"... How do I pick one?"

"We just have to put in an application and then interview with multiple coaches to see if one is fitting." Gree stated.

Naruto nodded.

Sounded... normal enough.
