Beasts Within

Disclaimer: I do not own Naruto or Prince of Tennis. I do not own anything besides the original characters that are included in the fanfic.

All the Jinchuuriki are around 12-15 years old to stay within the middle school category along with the rest of the PoT cast. I know that the ages are wrong; I'm just making them fit into the storyline. All of the canon characters will most likely be OOC considering I can't stay to a certain personality of a canon character no matter what I do. The Jinchuuriki have total control of their Bijuu but can still talk to them whenever. When they release the chakra of their Bijuu they become stronger of course and their voices are a mixture of their voice and the bijuu they contain, therefore 'Demon Enhanced Speaking' when they do activate their powers.

Tail 25: A New Start

It was another sunny day within Japan. The nine Jinchuuriki were still playing as tennis regulars, and most of the others did not know a thing about the ninja world. The only ones that knew about the ninja world and the Jinchuuriki were Marui and Kirihara.

The Jinchuuriki felt that the two had found out after seeing them fight against the Akatsuki during Regionals. The others had been surprised and hadn't talked to the Jinchuuriki. But something later happened which caused the others to come back to the Jinchuuriki and accept them. None of them ever remembered the impact that one certain girl had in their lives.

The nine Jinchuuriki couldn't remember who put the wrist seals on them, but they were grateful that they wouldn't be able to hurt their teammates in any practice matches. They weren't even able to remember how they had even gotten a mansion in Japan in the first place, but none of them complained about it. It was the only home they had in this world after all.

The tennis regulars were glad that the Jinchuuriki were back with them and that they had another chance to shoot for Nationals.

They never thought that they would ever be any happier.

Strange things started happening however. The Akatsuki attacks were less frequent which worried the Jinchuuriki. They couldn't help but think that they were planning something big with the Bijuu contained inside of them. They didn't realize the help they had all along during the few months after someone's disappearance.

Everyone was busy preparing for the Japanese Training Camp which everyone would be going to. They were going to face against America, and the nation needed to choose a team to go against them. The Jinchuuriki were their own little group coached by this one female coach at the camp. She looked to be about 25 but was actually around her early-thirties. She had black eyes with silver spots and her hair was a mix of blue with red tints. She wore a one-shouldered green and blue shirt with the sleeve going to her wrist. She wore dark blue jeans where one leg went to her knee while the other went to her ankle. She also wore light yellow slip on shoes as she worked with the Jinchuuriki. The new coach was named Estrella.

"What are we going to do today coach?" Naruto asked jumping around his best friend Gaara. The two Jinchuuriki had gotten much closer since their time at Shitenhouji. It was nearly impossible to break them apart. The same went with all the other pairings. Every pairing, or three considering Utakata, Han, and Roshi, were getting along nicely without so many fights breaking out.

They thought that it would be nice for a change to just have a group to themselves. It had been a few years since they had been like this…together without being on the run that is.

The only thing they couldn't believe about Estrella was the small white fox that followed her around. The nine Jinchuuriki along with the other regulars didn't know what the fox was doing here but were told by Estrella not to question it, or she would double everyone's training including those not in her group.

A week passed and everything was going normally. The nine Jinchuuriki couldn't believe that the fox was normal as it acted like a civilized pet, following Estrella around everywhere. They even caught the fox glancing towards them at random times before turning her head back quickly. When they asked what was the fox's name, they only got the word Yuki.

That day, something was more suspicious. Yuki was taking a walk around the buildings searching for something. The little fox did not realize that she was being tailed by the Jinchuuriki and the other tennis regulars. The coaches had all decided with some major influence from Estrella that they give the regulars the day off from training while also discussing who they would put on the team for the match against America in a month. They were discussing who was good right now and who they could help improve for the match.

Yuki stopped at the water fountain and jumped onto the ledge. Raising her leg, she started scratching her ears. She stopped suddenly which confused the people tailing her.

Lowering her leg, Yuki stared at the bushes nearby until a whizzing sound could be heard.

A net appeared from the bushes and surrounded Yuki. The little fox kicked and yelped while trying to get out from the net.

The people that shot the net came out of the bushes and surprised the group of people tailing the fox. They could not believe that the Akatsuki of all people would try and capture a little fox.

"Finally caught the little brat," Kisame said with a sigh as he picked up the fox by the scruff of its neck. The fox gave off little yelps of anger as well as snarls and growls while kicking at the man's hand to release her.

Smirking, Kisame threw the fox in the air before swinging his sword at the small animal. He cut the animal on the leg but didn't catch the fox giving him a smirk.

Kisame didn't realize it was too late until the fox appeared in front of him in a flash and clawed at his eyes. He was able to avoid going blind, but that didn't mean the scratches on his face didn't hurt.

"What would they want with a little white fox?" Utakata asked in a whisper while staring at the little fox who was dodging shuriken after shuriken that was being thrown at her.

The tennis regulars could only stare as the fox moved around gracefully. "What weird people…" Marui commented popping his favorite gum.

That seemed to be a mistake as the Akatsuki turned in their spots and stared at the group of people.

Said group of people were frozen with shock and mentally scolding Marui for his carelessness.

"Well, well, well," Kakuzu started while clucking his tongue. "Seems we have company."

Hidan was smirking at the group before he swung his scythe at the group yelling, "Die you Jinchuuriki scum!"

The Jinchuuriki could only stare as the scythe moved closer to them at an insane speed. As the group of people closed their eyes expecting them to be cut in half, they heard a clang of metal against rock.

Opening their eyes quickly, the Jinchuuriki and tennis regulars stared at the rock wall in front of them. Blinking in confusion, the entire group looked around for the ninja that dared to help them. They saw no one around them before a huge smoke cloud appeared from the rock wall disappearing.

For the next few minutes, all the group could hear was the sound of fighting. They didn't know who was fighting the Akatsuki, but they hoped that the ninja would win against them.

As quickly as the smoke cloud had appeared, it had disappeared along with the Akatsuki. All that was left of the battle were the occasional marks along the ground thanks to the weapons.

Looking around the area, all the group could see was Yuki on her side on the ground. Her leg was bleeding, so Fu quickly but gently picked the fox up and took her to Estrella to treat.

As soon as Estrella saw Yuki, she quickly took the fox out of the Nanabi's Jinchuuriki's hands and excused herself to go inside to her room.

Setting the fox down on the bed, she quickly grabbed some bandages to wrap around the fox's cut leg.

"You have to be more careful Yuki," Estrella commented after finishing the wrapping. She saw the fox give a small nod before the fox reopened her eyes. They were golden in color and full of determination. "Try to behave Yuki," Estrella commented while putting away the first aid kit. "I'll go get some food alright Yuki," she said over her shoulder as she exited the room.

Yuki limped over to the window to see the regulars practicing along with the other Jinchuuriki. A form glowed behind the fox, and the two put a hand or paw onto the window glass. Both the fox and the girl stared at the group in sadness before both said one phrase, "Be careful…"
