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

"Chat" Demon enhanced speaking

This is important. I just realized I only have a few weeks until school starts, and I still have twobooks to read, an SAT test to study for, two packets of 4-page worksheets to finish, AP Bio work to finish, work to do for other stuff, and a whole mess of other things. Becoming a Senior in High School is stressing me out a lot to where I can't even think of some of my fanfiction without worrying about school work. I think I'll do what SkyGem is doing on her profile page and post little journals on my profile. Please enjoy the chapter and wish me luck with all my work heehee~

Tail 23: Monsters…That's All That They Are…

"What are they?" the tennis regulars yelled at the same time when they saw the ten Jinchuurikis transformed.

"Get them!" Fu yelled in a demonic-voice. The other Jinchuuriki were used to the changes in their voices as their Bijuu had more of an influence on them in this form. They called it 'Demon Enhanced Speaking' as their voices sounded more demonic in this form than in their normal selves.

Every one of the Jinchuuriki nodded in response before heading off towards their opponents. Rose took an opponent from Naruto by deciding to fight Itachi considering Naruto never liked fighting the Uchiha clan because of their Sharingan.

"Ready to die Akatsuki?" Rose threatened the male snarling to show her new fangs as well as flexing her claws. She was walking in a circle across from Itachi who was doing the same. Her tails flicked in the air letting off an element or two from time to time. Knowing she couldn't be captured and put the others in danger, she kept walking in a circle but farther from the tennis teams and closer to the opposite side of the courts. She noticed the circle she had drawn earlier start to recede until she would need it again. The best part was that the seal would only react to her chakra, so the other Jinchuuriki would no longer to worry about whether the Akatsuki could seal them up with it.

"Oh on the contrary…" Itachi said with a blank stare as he activated his Sharingan. "Tsukiyomi!" he ordered locking his gaze onto Rose's eyes.

She quickly shut her eyes and kept them closed before the Genjutsu could take place.

"Smart little girl," Itachi commented keeping his Tsukiyomi in place. "But not good enough," he remarked as he charged at the girl.

The others could only stare as Rose was trying to dodge all of the jutsus and attacks that Itachi was sending her way with her eyes closed. She was clearly at a disadvantage with her eyes closed. Rose couldn't open her eyes, or she would have been trapped by the Genjutsu.

"You are dead," Rose commented using her tail from Shukaku's spirit to slam the ground and create an earthquake to disrupt Itachi's footwork. Next, she used Nanabi's spirit's tail to sense where Itachi was in the air. She had been using that tail to figure out where Itachi was, so she could dodge the next attack. When she found Itachi, she flared all nine of her tails out and released an elemental wave, one from each tail, at the male. Three of the waves were able to hit Itachi with the other six missing their target. Snarling, Rose made the six waves curve toward the other Akatsuki members and strike them.

The six Akatsuki members that were hit by the attack were surprised which gave their Jinchuuriki opponents a chance to injure them critically. The six Akatsuki backed off and let the remaining four do their job while the six started to heal themselves.

The ten Jinchuuriki gathered up in one area to see that Itachi, Kisame, Pein, and Hidan were the last ones left. The others had been hit by Rose's elemental waves.

Panting, Rose glanced at each Jinchuuriki to see that they were all partially injured but not critically. She was about to collapse from chakra exhaustion from using the seal as well as the elemental waves. Using the Bijuus' tails was also draining on her chakra. The others were fine as they only had one spirit that fed off her chakra. Rose had nine spirits feeding off her chakra to let their power flow through her.

"Rest a while Rose," Utakata whispered as quietly as he could to Rose. "You deserve it girl," he commented getting in front of her. Sensing a nod from the girl, Utakata smiled before charging at the remaining four Akatsuki along with the other Jinchuuriki.

Rose stayed behind like Utakata had asked and watched for any surprise movements. She walked back to the area where the tennis teams were. Noticing them backing away from her, Rose sighed before getting in front of them and turning around to face the battle. She was kneeling on all fours and looked like she would pounce on the closest enemy that got near them.

The tennis teams were scared of the girl in front of them. Even the girl's childhood friends were scared of her now that they saw what she was. She looked like a monster, and they thought she was a monster with her power, speed, and attacks. The girl created an earthquake just by slamming her tail!

Rose could sense the fear and worry inside each of the tennis players as well as the spectators. She couldn't help but let her eyes droop in sadness before she returned her focus to the battle in front of her. "Watch out! Kisame's above you!" Rose yelled out before pouncing out of her spot and right at Kisame colliding with him. She caused him to go off of his original course.

Kisame scowled before bringing his sword down on Rose's forearm successfully cutting it.

Rose felt her chakra drain even more because of it and quickly hopped off of Kisame's shoulders back to the tennis teams. She was on all fours again but was leaning off of her injured arm. Growling at the pain, Rose continued to watch the Akatsuki for any sudden moves when she finally saw it.

Konan had finished healing herself and threw her arm out to send paper birds out at the group. Deidara was healed as well and sent in his explosive clay birds.

The Jinchuuriki weren't paying attention as they were fighting the remaining four Akatsuki.

Rose couldn't stand just sitting there doing nothing, so she flailed her tails once more sending out elemental waves, one right after the other.

Each of the elemental waves collided with the paper birds and the clay birds before they even reached the fighters.

Rose kept sending out elemental waves until she was sure that Konan and Deidara were done using their chakra. Panting, she slowly let down her nine tails and watched as the nine Jinchuuriki pushed back the four remaining Akatsuki members.

Standing up once more, Rose slowly stumbled over to the Jinchuuriki and glared at the Akatsuki. "Leave this world and us alone Akatsuki. We won't hesitate to kill you next time around," she threatened the ten ninja before snarling.

The other Jinchuuriki followed her by snarling at the group of ten as well before lashing out their tails at them.

Scowling, Pein just remarked, "Mark our words, we will get you and your Bijuu. We will see to that." After that, the ten ninjas shunshined away from the battlefield and went back to the ninja world for some recovery.

Sighing, Rose along with the other nine let their chakra stop flowing through their bodies and let down the protective aura around themselves.

Each of the Jinchuuriki besides Rose started to collapse out of chakra exhaustion. Rose was exhausted as well, but she wouldn't show it to her fellow ninja or her fellow tennis-mates. Coughing a bit from the damage she had taken, Rose helped carry the least able ones back to the benches at the side of the courts. After setting them all down, Rose got each of them to take a soldier pill. She took one herself in order to try and recover her lost chakra thanks to the seal, the protective aura, as well as that blasted chakra-absorbing sword of Kisame's…..

"Wh-What are you?" they heard a voice stutter out in fear. Turning around, the Jinchuuriki noticed that Josei Shonan was the school to ask that question with the others behind them.

"What are you people?" Atsushi said shaking his head with his eyes wide from fear. He was from St. Rudolph and a childhood friend of Rose's.

The Jinchuuriki let their gazes wander everywhere but the tennis regulars. Rose was the only one with her eyes closed as she was still panting because of the pain. Using the Bijuu seal and breaking five of her own personal seals were a bit of a pain. Now her seals were trying to force themselves back onto her which drained even more chakra. Her legs were about to buckle until she locked them in place.

Only one person noticed this while the other teenagers were either staring at the Jinchuuriki or staring at the ground because of being one. "Are you alright Rose?" Marui asked staring at the girl's knees.

This snapped the Jinchuuriki's out of their gazes as they stared at Rose who had her eyes closed and was panting. "Are you alright Rose-chan?" they all asked with a worried look as they gathered around the girl.

Rose didn't respond to them with words but with a different way. Her knees buckled, and she fell toward the ground.

Quickly catching her, Marui turned her in his arms to see that her face was flushed, and she was panting harshly. He felt her forehead and noticed that it was burning. "Get her home," Marui said looking at the other Jinchuuriki, "Now!" he demanded with a yell.

The Jinchuuriki were quick to follow his orders as Fu gently took Rose from Marui's arms and positioned the girl on her back for the way home. They all nodded at Marui in thanks before they sprinted over the fence and sprinted their way back to the mansion.

"What do we do with them now?" another person asked their tennis captain.

"Honestly," Atobe said with a sigh, "Ore-sama has no actual idea what to do with the gakis."

"Neither do we," Yukimura, Tezuka, and the other captains replied.

"You aren't going to ban them are you?" Marui asked his tennis captain.

"She lied, and she is dangerous Marui," Sanada explained. "I don't think we have a choice to do anything but that."

"But she was protecting us!" Kirihara yelled. He didn't know this fact about Rose, but he didn't let it affect him as much as it affected the others.

"We still have no choice though," Yanagi said. "At this rate, no one will be able to trust her or even work with her. We have no choice but to ban her from club activities."

"That can't be!" Kirihara yelled. He could not believe that even Yanagi was saying that Rose should be banned. "Why does she have to be banned?"

"Not only her but every one of those brats," Atobe clarified.

"Why?" Kirihara yelled at him.

Yukimura was tired of this, so he said to Kirihara, "For the same reason as her Kirihara. Now enough of this, she betrayed us, and we don't take kindly to traitors remember. We play to win it."

Kirihara growled before nodding in fake agreement with his captain. He could not believe that they would betray Rose like this just because she was-

"She's a monster along with the rest of those kids," Shiraishi, another of Rose's childhood friends from Shitenhouji, commented crossing his arms.
