R&R

Crystal dodged and jumped to the side, staring at her brother in disbelief as he continuously lunged at her. She heard the sound of metal crashing on metal, then realized she automatically brought her sword up to protect herself. She couldn't bear to hurt her brother; she wouldn't.

"Takeru, please, stop!" Crystal shouted desperately.

His sword shot forward, a nicked her shoulder; blood flowing down her arm warmly and hitting the ground with a patter. She blocked the next attack, feeling her brother's strength push on her sword, making her arms shake from the strain of holding against him.

"Takeru!" Sakura shouted, gripping her brothers arm and pulling against him.

He glared at her before flinging his arm and sending her sliding across the floor. Mamoru stopped her as he stared at Takeru incredulously.

"Nii-chan! Snap out of it!" Crystal shouted, her voice cracking.

He sword swung at her, making her duck and roll to the side, before bringing it up and stopping the sword as it swooped down at her. Her foot slipped, sending her falling onto her back. Takeru shouted out, and Crystal closed her eyes, ready for the finishing blow from her brother.

"Run," Takeru said gruffly.

Crystal opens her eyes and see's Takeru's eyes changing rapidly from red to blue and back to red. He was clenching his teeth to the point where it looks like they may crack.

"Takeru," She whispered, looking up at her brother, who was straddling her and straining his arms to stay still.

"You need to run," He growled out again.

He gasped as he gripped his head and his eyes flashed red at her threateningly again. He smirked evilly again as he looked at her, his hand reaching out and gripping the hilt of his sword with a fierce grip. He lifted it out of the ground and above his head, aiming the point of it down at her beneath him.

"Crystal!" Ace shouted, spotting her on the ground beneath the blade.

Teach knocks into him, sending him flying backwards before he could run after her. Crystal sucked in her breath and gritted her teeth, knowing there was only one thing she could do to help her brother at the moment and save her life. The only thing holding her back was that she was going to have to hurt him in the process by doing so.

She slams her hand into his chest, pushing the power that was building up in her gut, and sending it out into her hand. Darkness exploded out of him, gathering into a thick fog behind him, as if it was a being itself that was just expelled from inside of him.

Takeru screams as the explosion sends his body into an electrified state, and making him fall over next to her, and the sword to roll away. Crystal sat up quickly, just as the dark fog flew towards her and surrounded her dangerously.

Ryuuji flew out of her quickly, just as the fog flew towards her, ready to take her over as its new vessel and use her against her nakama. Ryuuji stays in his dragon form, as his jaw gapes open and he swallows the fog whole. Crystal grits her teeth as she feels Ryuuji's strength grow inside of her, threatening to overpower her with any slight weakness.

She gives her brother one last glance before standing up shakily. "Ryuuji, come."

"Can you handle it?" Ryuuji asks worriedly.

Crystal nodded her head, looking determinedly for her mother. She finally spotted her mother and smirked victoriously as she was standing alone with Akito's attention in other places. She raced forward without another thought towards her mother.

Akito spots Crystal nearing Rin, and gritted his teeth in anger. His thoughts became muddled as he began to rethink this victory he thought would come so easily. He shouts out and flies towards them quickly, arm locked back with a powerful explosion of darkness ready to hit her with its full force. Ryuuji saw him before Crystal did and put his arm up as he stepped in front of Crystal, taking the explosion from Akito and sending him flying to the side.

"Mom!" Crystal shouts, reaching her mother.

Rin raises her arms to try and touch Crystal; the only way she would be able to control her effectively. Crystal grabs her wrists before she can do anything. She looks her mother in the eyes hoping to pierce into her somehow.

"Please mom! Stop this! Can't you see you're hurting people! Your own family!" Crystal argued desperately, making her mother look at her and nowhere else.

Akito growls as he lunges at her again, but Ryuuji recovers himself and tackles Akito to the side, both of them rolling around and hitting each other in a scuffle. Both trying to get the upper hand. Ryuuji struggled against Akito as the power between them were both strong and nearly equal. But Ryuuji couldn't push it, knowing that Crystal was already fighting to keep him at bay as his power grew.

Her mother groans as she squeezes her eyes shut and grips her head in pain. "Crystal?"

"Yes! Yes it's me!" Crystal said, hope rising up inside of her. "Come back! Please, you have to stop this!"

"Enough!" Akito growls predatorily.

Power surged out of him in electrical waves, sending Ryuuji flying off of him, and hitting Crystal. They slid away from Rin in a heap on the floor.

"I will not let you take her away from me! You stupid, insolent child!" Akito shouted, his eyes flashing at her in anger and seething hate. "You will not win this war! And you will give me your power!"

"I will not!" Crystal shouted at him as she got out from under Ryuuji and glared at him.

"Crystal!" Sabo shouted as he and Lily raced towards her.

He cloned himself, jumping at Akito with a glare, his clones numbering him 50 to 1. Lily snapped her fingers and pushed her hand out, sending a powerful force towards Akito as she reached out with her mind.

Akito glared at them, leveling his glare on them from Crystal. He roared as he outstretched his arms and flung them back with another electrical wave. They got up quickly, but stopped as more men surrounded them and kept them at bay from Akito and Crystal.

Crystal stared in horror as she looked at the men closely, seeing that they were covered in bruises and mortal wounds. She looked around at all of them and covered her mouth. Every one of the men working for her mother and Akito were constantly being injured with wounds that would kill any normal person, but here the men just kept getting up and fighting again. She realized with a shock that her mother was controlling them like dolls as the darkness Akito was feeding them gave them strength and power.

Her side were slowly being pushed back towards the ships, leaving her defenseless and alone. She shakes her head, not wanting to believe that they are losing this fight because some men are becoming the walking dead.

"Mom!" She cries out. She looks desperately at her mom who was still struggling with herself.

She gets up and runs to her mother, grabbing her by the shoulders, shaking her. Akito spots her and growls, racing towards Crystal angrily. He grabs her by the throat and squeezes, cutting her air supply off, and making water appear in her eyes from the burning pain suffocating her lungs.

"M..o…m…" She grumbles out, glancing at her mother.

Rin looks up and stares at Akito holding her daughter in the air by her throat, making her snap out of it momentarily and stare in shock.

"What are you doing?" She screams at him, glaring at him quickly.

She thrusts her hand out and shoots an explosion inside of his head, making him scream out in pain and drop Crystal. She lands on the ground like a rock being taken over by gravity, gasping for the desperate air that her lungs need.

She looks up and stares in fear as she spots Teach grabbing Whitebeard by his arm and slamming his fist into his chest. An explosion erupted inside of Whitebeard from the darkness enveloping him from Blackbeard's fist. Whitebeard coughed, as blood spurted out of his mouth.

"Daddy!" She screams, reaching out her hand towards him.

"Saki!" Rin shouted, sending her dragon towards Whitebeard and flinging Teach back away from him with a powerful gust of wind.

"Mom," Crystal said thankfully, getting to her feet.

"Crystal, quickly, save your friends. Save your brothers." She began to struggle with herself as Akito grabbed her arm and bruised her skin from his tight grip.

"You will stay as you are." Akito commanded her, darkness seeping into her skin.

Her mom looked up dazedly as her eyes melted back to the red they were before. Crystal held back a whimper as Akito leveled his gaze on her once again, fear freezing her blood and hardening her bones in place.

"I've had enough of you trying to ruin my plans." Akito growled at her, walking in front of her and lifting her up by her wrist. "You will give me that power."

"I can't," She whimpered out, limbs shaking. She grits her teeth and slams her hand over his chest, exploding the darkness out of him.

He growls angrily and throws her aside, sending her flying off the platform, landing on the ground painfully. She groans as she felt a couple of her ribs crack from the impact. She glanced up and saw Akito looking down at her with a fearsome glare, calling the darkness back into him.

"It's impossible," She whispered scared. "He's been completely consumed by the darkness."

Akito looked over from her. "Shichiro, kill her."

Shichiro stopped from joining the others in fighting, and looked at Akito in shock. "You said we wouldn't kill her! That we would just take her power and leave her alone!"

"Taking her power would kill her!" Akito yelled at him. "She was going to die anyway!"

"I won't kill her!" Shichiro shouted at his father, looking helplessly at Crystal. "I'm sorry, I didn't know!"

"Then I'll kill her myself!" Akito shouted.

Crystal rolled to the side, dodging as he jumped down to her. She stood up quickly and punched him across the jaw, making him grab her wrist and twist it behind her.

"What do you think would hurt you more?" Akito said laughing behind her. "Killing you, or making you watch again as I kill your whole family?"

Crystal tensed as she looked helplessly at Shichiro, begging him to help her with her eyes. Akito grabbed her chin painfully and made her look at her family that is slowly being defeated, tired, and pushed back towards the ship.

"Say good bye to your new family." Akito growled, gripping her tightly.

He raised his arm up and pointed it at the front lines of the battle, where Ace, Luffy, Marco, Thatch, Sabo, Whitebeard, Sakura, and Mamoru were. She desperately gripped at Akito, trying to move his arm away from the intended target. Akito formed a ball of darkness in his hand, waiting as it grew and built in power, hitting Crystal with its raw strength and making her heart beat like a hummingbirds wings in fear.

"Daddy! Ace!" Crystal screamed quickly, looking at them, hoping they would hear her and run. "RUN! NIGETE!"

They heard her and looked over just as Akito let the dark ball out of his hand, shooting it across the clearing towards them. It grew ten times its size, at least double the size of Whitebeard. Crystal stared in horror as the ball shot across and consumed its own side as it headed towards the front lines. Men screamed and yelled as their bodies were consumed completely from the darkness, their skin, muscles, and bones melting and disappearing completely.

"YAMETE!" Crystal screamed as the ball soared closer towards her family.

Akito stared down at her as her power built inside of her, swirling around her dangerously. His eyes widened in surprise as red raw power swirled around her and she gritted her teeth in anger. She suddenly disappeared out of his hold making him take a step forward and look down at where she was a second ago.

"I WILL NOT LET YOU KILL THEM!" Crystal screamed, appearing before everyone on the front line.

She looked up determinedly at the ball flying towards her. She lifts her hands and grits her teeth in pain as the ball slams into her barrier she created in front of her. The ball continued to roll, pushing against her with its full force. She pushed desperately on the balls of her feet, but the force was too strong, it began to push her and make her feet slid on the ground, causing trails of trenches where her feet were digging in.

Akito and Shichiro watched in horror and shock as Crystal pushed against the ball, keeping it from hitting her family and nakama behind her. The pirates and Marines stared in surprise as the ball started to slow down.

"Crystal!" Sakura cried out.

"Nee-chan!" Mamoru said helplessly.

Spurts of darkness whipped out of the ball and past her barrier, hitting her and cutting her all around her body. It hit her arm, thigh, and stomach, sending her body into panic. She gasped as another shot hit her in her hip, her legs trying to buckle underneath the pain.

"Crystal!" Whitebeard said, trying to step forward towards her.

"No…" She ground out. "Stay back!"

She looked back at the others and let out her breath, before taking another deep one. She looked up determinedly.

"Ryuuji," She said calmly, feeling his power grow inside of her. "Chii, Momo,"

She waited, feeling the two dragons surround her with their power, before seeping into her body and increasing the power inside of her. She smiled and pushed that power out of her and into her hands, making the ball in front of her stop rolling, then roll the opposite way.

"Dai, Chairo, Haru." She added, knowing how much her body was screaming in pain from the power.

The power surged inside of her, making her yell out in pain, before concentrating that pain and making it surge in her hands. The ball exploded out from her barrier and flung back towards Akito, ready to consume him just as it consumed his allies.

Akito stared wide eyed at the ball racing towards him. He lifted his arm and hit the ball to the side, as if it was a fly coming towards his face annoyingly. It hit the ocean, making that section exploded and keep the water straight into the air.

"Cheeky little brat," Akito gritted out. "Shichiro, you fight her or you'll be the one to die."

Shichiro flinched at the threat in his voice, making him gulp and look at Crystal helplessly. He lunged forward and aimed his fist at Crystal. She flinched, but felt someone reach around her and grab the fist, flinging him away from her.

"Don't you dare touch her." Ace growled behind her. He looked down at her worriedly.

She looked back at her nakama behind her and saw all of them put their weapons and fists back up, ready to fight off anything else to come. She felt the need to cry as she saw all the wounds, bruises, and cuts on them, but still they were willing to fight alongside her.

"Can you fight off the rest of the men?" She asked them carefully.

Marco walked up and nodded, patting her on the shoulder, "Let's finish this."

Crystal breathed in and looked at the other dragon users behind her. "I know this is risky, but you have to let me use your dragons. Okay?"

"Knock 'em dead." Sakura said with a smile.

"Don't push yourself." Ace told her worriedly.

She gave him a small smile and kissed his hand that rested on her shoulder lightly. "I'll try."

She disappeared from all of them again and appeared in front of Akito. She pushed her hand up and smashed her palm into his nose, breaking it and sending him backwards a couple of steps.

"You bitch!" He shouted angrily, holding his nose as blood spilled out.

"Shut up," She growled at him, making him jump. She walked towards him with her hands balled into fists. "I'm not the same little girl I was years ago. I won't let you take them away from me."

"Ha! You think someone like you can defeat me?" Akito scoffed at her.

"Not alone I can't. But with everyone's help I know I can." Crystal told him.

She disappeared again, making Akito look around helplessly, and prepare for an attack from her. When nothing came he tensed and quickly looked behind him.

"No!" He shouted.

Crystal had reappeared in front of her mother and grabbed her arm. She placed her hand over her chest, letting the power explode from her hand and shoot the darkness out of her forcefully. She screamed out in pain before collapsing backwards.

"I got you." She said quietly.

She caught her mother protectively and laid her on the floor gently, brushing the hair out of her face. She looked up and glared at Akito, seeing him shoot forward angrily towards them.

"You will no longer control her." Crystal growled at him.

She stood up and glared at Akito, calling out the dragons and making them stand next to her in their silhouette forms. The stood around her protectively, glaring at Akito with their colored eyes. Rin groaned on the ground, before sitting up and rubbing her head in pain.

"Crystal?" She said, looking at her daughter sadly. "I'm so sorry."

Crystal shook her head, keeping her eyes on Akito and glancing at her mother as she stood up and stood next to her.

"I can't believe you controlled me like that and used me to hurt other people!" Her mother shouted angrily at him.

"You would have left if I didn't!" He shouted desperately at her.

Her mother opened her mouth again, ready to argue more, but Crystal held up her arm and stopped her mother from saying anything more.

"Right now isn't the time to argue." Crystal said. "Can you take care of him?"

Rin looked at Crystal hard, before nodding her head and glaring at Akito. "This will be payback for all these years."

"Don't let him gain control again." Crystal warned her.

Rin nodded once more, squeezing Crystal's hand affectionately before letting go. Crystal smiled and disappeared, reappearing in front of her brother Shichiro, blocking an attack he was aiming at Ace.

"You got him?" Ace shouted over the yells on the battlefield.

"Yeah!" She shouted back, nodding her head and piercing her gaze into her brother. "Why do you continue to fight for him?"

"Because I'll be killed if I don't." He growled back. "And unlike you I want to live."

Crystal narrowed her eyes, pushing her brother back. "You think I don't want to live?"

She rushed him, hitting him in the jaw, then straightening her leg out and kicking him up into the jaw painfully.

"I'm fighting so I can make sure I'll live! So I can live happily and safely with the people around me!" She shouted at him.

He caught himself and lunged at her, punching towards her face. She crossed her arms and blocked the hit, wrapping her leg around his and tripping him. He crashed to the floor roughly, and looked up at her confused.

"I want this to be over, so Akito can no longer threaten us! SO we can live our lives like we want to!" Crystal shouted at him.

She slammed her heel down towards him, making him roll to the side and do a handstand, before launching off the ground and landing a few feet away from her.

"We can never live a normal life! There will always be people out there coming after us!" He argued back, hurt flashing in his eyes.

"I know that! I lived with that when I thought you all were dead! I lived through that constantly, and alone!" She screamed at him, making him start and look at her. "You decide how your life will be. Show and prove to everyone else you're not how they think you are!"

Shichiro stood up straight and looked around at her family that was here fighting for her, helping to end this just as she wished. He glanced at the Marine's who joined up with her.

"Why," He said confused.

"Because they want to decide their own futures." Crystal told him, relaxing her stance and gazing at him with sadness. "No one wants to live in fear. No one wants to be used."

Crystal gasped as pain ripped through her, sending her to her knees in pain. She gripped her chest and felt her heart struggling to keep up with the great amount of power coming out of the dragons inside of her.

"Oi!" Shichiro said, kneeling down by his sister.

"See? You're still my nii-chan." She said with a small laugh.

He looked at her surprised before glaring at her and standing back up. "no I'm not! You always had everything you wanted. Our parents always wanted you. I was never seen when it came to others."

He thrust his hand out, thick vines coming out of the ground and wrapping around Crystal's body, sending her into the air and holding her there.

"I'm doing this for myself!" He shouted at her.

She looked at him helplessly as laughter erupted behind her. She looked and found her mother lying on the ground near Whitebeard as they all stared at Akito in horror.

"You think your mother could have stopped me?" Akito shouted incredulously. "I was the one to give her power!" He looked at Shichiro proudly, as he walked over and examined his son's work as if it was a master piece in an art show. "Good work, son."

Shichiro clenched his teeth, fighting internally with himself as Crystal's words processed in his mind. He looked at Crystal and saw her struggling to stay conscious, he could see how much she was risking in this fight; including her life.

"Why do you fight so hard?" Shichiro asks her.

"Because," She says, breathing heavily as her body felt like it was being ripped apart. "I want to live with the people I love. I don't want to feel like they can be taken from me. I want to live my life with them."

Shichiro froze, seeing her eyes gaze back up at him. He turned and saw Sakura, Mamoru, and Rin gazing at him in pity as they saw how much Akito was using him.

"He's using you Shichiro. He'll throw you away after he has me." She told him sadly.

"No! He won't!" Shichiro said.

Akito began to laugh even more as he clapped his hands for Crystal. "Good job. You found out my plan huh?"

"Yeah," She said. "You want to use all our powers, and bring them into you. Like darkness consuming everything around it."

"Bravo," Akito said with a vicious smile. "Too bad that won't save you."

Akito lunged towards Crystal where she was being held immobile. Shichiro yelled and sent the vines to let her go and instead hit Akito with it's full force. They wrapped around him and soon consumed him till he was no longer in sight.

"Shichiro!" Crystal shouted out worriedly.

She stood up and ran to her brother, tackling him down as Akito exploded the vines out and glared at his son in fury.

"So you're on her side now too!" Akito growled, pointing an accusing finger at Shichiro. "You will all die!"

Crystal stood up with Shichiro, facing Akito down with their glares. The others stood protectively behind her, keeping their gazes on him also. His smile soon was replaced with a fearful frown as he backed away from them and shook his head.

"You won't defeat me!" Akito shouted at them defensively.

He looked all around, looking for something that could help him win. He snapped his fingers, making the men that were on the ground defeated, stand back up and fight again. They charged all of them, sending the battle into a last minute frenzy.

Crystal and Shichiro ran into the battle, hitting anything that came close to them. Crystal effortlessly dodge the attacks by jumping and flipping over them, as Shichiro finished them off by making the vines capture them and hold them were they were.

Crystal landed closer to her nakama, cringing as pain flared through her again. Shichiro looked at her worriedly as he held out his hand. She looked at it confused, by relaxed as he smiled at her.

"Take mine." He told her.

She smiled at him, nodding. "Midori," She said calmly, feeling his dragon wind around his arm and into her. She looked back at her mother and sighed. "Saki,"

Her body was screaming as it was taking it's limit on the power. She composed herself determined not to show how much pain she was in. But she knew she wouldn't last a couple more minutes. She hated to go back on her promise, but she wasn't going to let Akito win.

She clapped her hands, and opened them up above her head, gathering each of the dragons special powers above her into a giant swirling mass. Akito looked at her in horror as the ball grew and threatened to attack him at any moment.

Crystal gritted her teeth and took a step forward, throwing the ball and releasing the pent up energy along with it. The ball soared towards him, rolling inside with power so great it could destroy the whole world.

"NOOOOOOOO!" Akito shouted, putting his hands up to stop it.

It crashed into him, exploding on impact and causing debris and dust to fly into the air, blocking out any sight in front of them.

Cheers erupted behind her as the other men collapsed back onto the ground, no longer being controlled by the darkness that was inside of them. Crystal turned around and smiled at all of them victoriously, waving her hand in the air towards her family.

"We did it!" Mamoru shouted happily.

Crystal stared at her family, glancing at her siblings one by one and then to her mother. That was when she noticed that Takeru wasn't fight with them, that he may have still been on the floor from her expelling the darkness out of him. She looked around the battle ground, before looking back at her family, that were congratulating each other.

The darkness was flying out of the bodies, joining together in the air before zooming behind her. She froze realizing everyone else was too preoccupied with celebrating to realize what was going on.

Laughter erupted behind her once again, sending chills through everyone.

"Kill her," A dark sinister voice growled out.

Crystal turned, to see Akito forming once again into his body, the darkness that the others were controlled by, now forming to create his body. Her breath hitched inside her throat as she stared in disbelief at what was happening.

She turned and stared at her family in fear, knowing that that was their last chance in winning this. Shichiro screamed her name out, as Ace and Marco stared wide eyed and took a step forward.

Crystal turned around and froze, feeling the blood flow out from around her chest and down her front, before soaking the floor below her.

"Ta…ke…ru…" She said quietly.

Takeru stood there with shaking hands as he looked at the sword he had plunged through her chest. His eyes faded back into their blue as he stared in disbelief at what he had done. He pulled the sword out of her, let it fall out of his hand, and clatter to the floor. She placed her hand over her chest, looking up at him in shock as it processed in her mind what just happened.

"Crystal!" She heard her father shout out over everyone.

She turned to look at him. "Da…ddy." She said painfully.

The dragons swirled around her before expelling and disappearing, as if dying from inside of her. Blood trickled from her mouth and down her chin, as the pain finally flared from in her chest and out into the rest of her body.

Ace raced forward as Crystal smiled at him, feeling oddly at peace as her vision slowly faded and turned to darkness. She fell forward and felt strong arms wrap around her.

"No! You can't die!" Ace shouted at her, making her open her eyes and try to focus.

She felt water patter on her cheeks, as everyone surrounded her in shock. She reached up and cupped his face, wiping the tears from his cheeks.

She smiled at him, hoping to make him feel better. "I'm sorry. I can't finish this." She told him sadly. She coughed and more blood sputtered out of her. "Maybe it'll be safer now that I'm gone."

"Don't say that!" Ace shouted, brushing the blood from her mouth, and pushing her hair away from her face. "You have to stay with me."

"I'm sorry," She whispered, feeling her heart slow down.

Her breath escaped her as her vision turned black once again. She felt herself be carried away as she no longer could feel everyone around her or hear them. She was glad she had the time she did with Ace. She just hoped he would find someone else. She just wish she didn't die before defeating Akito.
