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.

"Chat" Normal talking

'Chat' Thinking

'Chat' Telepathy between Jinchuuriki

Tail 18: Accidents Happen

A month passed since Rose and Marui had visited Josei Shonan. Rikkaidai was training like their lives were on the line…which could have been true considering how hard Sanada was working them all in the training sessions.

"He's such a slave driver," Kirihara panted out after running about 50 laps around the tennis courts.

Rose was also panting and had her hands on her knees. "No kidding," she growled before standing back up and popping a small green candy in her mouth and tossing one to Kirihara. She had only given the soldier pills to the tennis regulars because their training seemed to be the hardest out of everyone's in the club.

Yukimura looked at the two of them with a sly look on his face. "Rose!" he called out all of a sudden causing the two to jump startled by the sudden yell.

"What is it buchou?" Rose yelled back clutching her chest with her hand trying to get her heartbeat down. She was beginning to slowly trust the regulars. Sure they weren't fully trusted by her yet, but she was working on it along with Kirihara's help.

"I want you to play a match against Marui please!" Yukimura yelled back with a smile on his face. One reason for the smile was because he was happy that Rose was starting to trust the team more and more, and another reason was because he wanted Rose and Marui to get along more. He was starting to notice how Marui was more alert with Rose nearby and more suspicious of the girl with every visit to her mansion.

With a sigh, Rose just replied back, "Alright then!" before heading over to the court where Marui was waiting.

"Ready kid?" Marui asked popping his favorite gum when Rose arrived.

"More than ready," Rose answered with a smirk of her own and went to the receiving line. She always let her senpais serve first for some odd reason that her teammates could not comprehend.

~Time Skip~ One Half-Match Later

"Someone get a nurse!" a tennis non-regular yelled out as they saw what had happened on the courts between Marui and Rose.

Marui had used another tightrope-walking technique, and Rose thought she would be able to make it to hit the ball back to get the game. She did get the point…but at a cost.

When Rose had actually hit the ball back over to Marui's side of the court, she was going too fast to slow down or stop and crashed into the net pole. Her head smacked against the pole knocking her unconscious.

The tennis regulars widened their eyes when they saw it happen in front of them when they were watching how much the girl had improved.

Kirihara was gritting his teeth before he ran out to the courts trying to make it to Rose.

However, Marui reached her first and applied pressure to the area where the girl hit her head. Her forehead was bleeding a bit because of the impact, but it looked like she was fine.

Kirihara finally made it up to them and applied pressure to Rose's forehead while Marui picked her up in his arms.

"Take her to the infirmary now!" Sanada yelled out at the two conscious regulars who nodded quickly before running off. "That girl never seems to stay out of trouble," he said shaking his head. Even though he was stern, he was still a bit worried for the female regular. She was training the hardest out of everyone to 'keep up' with everyone. She was even doing extra training at home from what the regulars could tell when they saw Rose sneak out late at night to practice.

"Think she will be alright?" Kirihara asked worriedly as he and Marui ran to the infirmary to get help for Rose.

Marui looked down at the girl in his arms and just said, "She always will….always will…"

This seemed to encourage Kirihara because he sped up a bit faster to get to the infirmary quickly along with Marui.

"Nurse!" they both yelled once they made it inside.

"What is it?" she yelled turning around quickly in her chair.

"Rose needs help. She crashed into one of the tennis poles while trying to return Marui-senpai's 'Tightrope Walking' technique!" Kirihara yelled already helping Marui set Rose on the bed in the room.

"Let me just test a few things then," she said grabbing a few papers and a pen before asking the two to leave for a bit while she checked everything.

The two regulars left and paced outside of the room. Marui thought ahead and texted Yukimura and Sanada while waiting. He told them about the two staying with Rose at the infirmary until they knew that she was okay. They got the okay to do so a few seconds later as if one of the two were actually waiting for a response.

The two paced around a few more minutes until they saw the nurse open the door and allow them to come inside.

Kirihara and Marui nodded before going inside quickly and seeing Rose. They went over to her bedside and took a look at her. Her forehead was bandaged because of the crash, and she was sleeping peacefully with her lips parted for air, her head tilted to the side towards them a bit.

"She looks cute doesn't she Marui-senpai?" Kirihara asked suddenly startling Marui.

"Wh-What?" he replied with a stutter.

"Oh come on," Kirihara replied with a smirk as he turned to face his senpai, "I notice how many times you look at her each day. You have to have a crush on her!"

Marui just glared at his kouhai and growled out, "I do not have a crush on her!" In his head, the red-haired male added, 'It's because I want to know what's going on with her. What secrets she is hiding. What is happening with the visits…'

An hour passed and afternoon practice was finally over. The other regulars came to visit the infirmary and got permission to carry Rose back home.

Marui was the one to pick her up again because he was the least tired and was stronger than Kirihara. Kirihara ran back to the clubhouse in order to get Rose's bags before rushing over to the school gates to meet them.

Walking to the mansion took longer than usual because they had to carry someone. The other regulars chatted along the way with Marui taking the lead and trying to get Rose back to her house. He couldn't help but think that something was going to happen to her because of this injury.

Not a minute later, a loud explosion was heard in front of the regulars creating an area of smoke surrounding the group. Marui felt the weight in his arms being lessened before it disappeared completely.

The smoke cleared to reveal two men in all black clothing holding Rose up by the collar of her shirt and a knife to her neck.

"Where are the others?" one of the two asked the regulars. "We know they are here, now where are they?"

"We don't know who you are talking about!" Kirihara answered before he started to wonder whether these men meant the group that Rose had brought along to meet Yukimura.

"You know who we are talking about boy!" the other man replied before scowling, "Don't mess around boy, or we will kill her!" To emphasize their point, they pushed the knife farther until a thin line of blood appeared on the girl's neck.

The Rikkaidai regulars all tensed and stood back before they heard another explosion behind them. They couldn't see well because of the smoke, but they could hear the drop of a person onto the ground as well as two screams.

After the smoke cleared, all the regulars could see was Rose on the ground with the two men gone and out of sight.

"Let's get her inside," Yagyuu commented, "quickly…"

The team nodded quickly in reply before Marui picked Rose up again, and started to run along with the others back to Rose's mansion.

When they got to the gates, they realized that they couldn't open the gates on their own and wondered what to do.

They couldn't get inside, and most of them started to panic besides the more stoic ones.

Marui thought back to whenever the team entered Rose's mansion. He had always seen Rose wipe some of her blood on the gates and the doorknob before they could enter the actual area. "I think I have an idea," he said before rubbing his finger across the blood on Rose's neck.

The others stared at him before widening their eyes when they saw Marui drag his bloodied finger across the gate. They were about to yell until they saw a faint flicker of silver before Marui pushed opened the gate. They followed Marui as he did the same thing with the door which they saw flickered black before opening as well.

As soon as they all walked in, Rose seemed to wake up. She raised her arms to wipe her eyes as she asked, "We must be at my house huh?" before she yawned with her hand over her mouth.

"How could you tell?" Niou asked staring at the girl in Marui's arms.

"Just can," she replied before jumping out of Marui's arms and out in front of them, "Come on then, you look like you saw a ghost." She started to walk towards the center of the mansion where the showers were and pushed them inside to relax. "Meet me in the living room in the front area if you want answers," she yelled through the door before the team heard footsteps in the direction of the room.

They all showered quickly and grabbed some food from the kitchen before heading back to the living room. They saw Rose reading a book on the couch. Looking down at her neck, the regulars could see that Rose had bandaged her neck to hide the cut she had gotten from the men before. They could see her eyes darting across the pages before they stopped suddenly, and she glanced up at them.

With a small smile, Rose saved the page in the book with a green colored bookmark and closed the book before setting it down on the table in front of her. "Come on," she said motioning towards the seats, "You must be tired after carrying me for so long."

They all sat down, and Rose started to explain what had happened, "Sorry, I must have not been paying attention much to my speed when I returned the ball. You see, I love to play the sport, but sometimes I go overboard as you can see," she said with a giggle at the end at how the match went. She saw the others nod before asking, "You must have also encountered some…unruly fellows outside huh?" Seeing the others nod again, she sighed before continuing, "Don't worry about them. They are just some sore losers from another country that I beat. They won't be bothering me anymore alright guys?"

Marui still looked a little suspicious about the entire thing and stared at Rose again with a blank stare.

Sensing the stare, Rose turned to look at Marui before giving a small smile and saying, "Don't worry about it alright, and don't worry about the match. Accidents happen. They always happen." She got up from her seat on the couch and decided that it was time to get some sleep for the next school day tomorrow. They still had to prepare for their tournaments and in a few months…the Regional Tournament…or as Rose remembered it…the day the Akatsuki would be able to invade…
