A/N:

Wow, Clarilune. For a sleepy person, you do inspire me greatly. I hadn't thought about the possibility of Yukia going with Sora for a while, leaving the Organization in a rumpled heap of [unintentional] sadness. So, I'm probably going to be using a few of these. XD

I'll wait until more come in, just to see if there are any others I like. But for now, I'm using a few of your ideas. Many events will take place in Chapter 13, so prepare for a long chapter!

[TimeSkip: 2 weeks]

Yukia had been told Vexen was sent to Castle Oblivion. She didn't know what that was, but it sounded pretty important, so she didn't question it. Instead, she had been staying in Vexen's room for long periods of time- coming out only every three days to eat and drink. She was losing weight fast, and she seemed a bit… lost in her mind. She stopped going to see Zexion to read, and stopped singing with Demyx into the wee hours of the morning.

Today, Axel caught her going to the kitchen. "Yukia!" He jogged up next to her, his trademark smile plastered on his face.

She briefly glanced in his direction, but didn't bother to respond.

Axel frowned a bit, and then smirked. "I haven't seen you in a while. What have you been up to?" By this time, they were in the white kitchen, and Yukia was looking through the fridge.

"I'd like to be alone,'' she turned to him, her face pale and boney, red eyes now faded to a dull brown.

"You look like you just went through Hell and back." He placed a leather gloved hand gently on her face, tracing her cheek bone and back down to her lips.

She didn't move, but shuddered violently, like she was unused to being touched at all.

Her hands shook, and she turned to put the grape jelly she retrieved from the fridge on the counter, and then turned to face him again. "You're… Axel, right?" she asked wearily.

"Yes," he said quietly. "That is the name they gave me."

She traced her tongue over the cracked flesh that was her lips. And, slowly, she smiled. But it looked painful, like she didn't remember quite how to smile. "I'm Yukia. I don't think I've ever properly introduced myself."

Using the word beautiful seemed to be a word inferior to what she was at that moment.

Axel's breath hitched in his throat, and he almost forgot how to breathe. When she turned back around again, she continued to make herself a sandwich. Axel wanted to say something, but no words would come out- like he had been frozen solid.

"Axel, who is that blonde child you hang out with?"

"Who? Roxas?" Axel looked shocked for a split second before regaining his composure. "What about him?"

She shook her head as she put back the glass container. "Nothing, it's nothing…" she took a bite out of her sandwich, but spat it back out- gagging on the sweetness of the jelly. She coughed continuously, and then ran to the nearest bathroom.

Yukia threw up what little contents she had in her stomach, and wiped her mouth as it happened. Why, Yukia thought, flushing the toilet and rinsing her mouth out. Where did he go?

Walking out again, she abandoned the thought of food to sleeping again, but she wanted something to do. She saw Xigbar out of her peripheral vision, walking to Xaldin and chatting about something.

Aw, Hell. She shrugged and walked in his direction. Why not?

Xaldin walked away from Xigbar, and the latter man huffed. "He never wants to go shooting with me…"

He felt a light tap on his shoulders, and looked down at Yukia, whom he hadn't seen in weeks. Her face was thin and boney, and she was pale as all Hell. Her hands shook with the light grip she had on his coat, and he gently brushed her off.

"Xigbar," she began, her voice cracking. "Can I go shooting with you today?"

He stood there, shocked, for a moments' time before responding. "Of course!"

Yukia's face flushed a pretty shade of red that looked unnatural on her pale, dying features. And then she smiled and wrapped those, small, lanky arms around one of Xigbar's own.

He poised his guns just right, and shot at the targets with perfect efficiency. Yukia clapped gingerly, and Xigbar made a muscle pump with his arm. Yukia laughed quietly, and smiled at him again. Her eyes glistened with something that hadn't been there since he first met her.

"Want to try?" He held out one of his Arrowguns to her, and she slowly got up and took it from him.

"How do I do this…?" she held the Arrowgun unsteadily, almost dropping it a few times. Xigbar laughed, and put down the other one.

Grabbing hold of Yukia's hand and arm, he helped her hold it. "Like this, see? Aim for the little red X in the middle of the circle."

[TimeSkip: 6 hours]

Yukia was exhausted, to say the least.

She had never had much training with guns, because she was more of a magic user. Her body was sore from shooting the Arrowguns, to sparring with Xigbar afterwards. Xigbar was carrying her back to Vexen's room, because she was too weak to walk on her own.

As he set her down on the bed, she smiled weakly and sat up.

"Thanks, Xigbar." She punched his arm lightly. "I had fun."

"No problem, sweetheart." He ruffled her hair and left the room, leaving Yukia all to herself. She stripped herself and summoned water magic, so she could bathe quickly. According to the moon-charts, tonight was a Full Moon.

"I really want to see it, but…" she dried off with a towel she had put by the bed. "Why does it feel like something really bad is going to happen?"

Saïx was quickly losing control of his senses; the light from the Full Moon illuminated his half-naked body, pouring over him as if it was nothing but water. He glowered up at the Moon, and then looked to his right. The form of a girl was there, but he could just be seeing things, right? His vision went red, and he lost complete control- going into his Berserker form.

Saïx growled at the figure to his right, and charged with the force he could muster from his newfound strength.

Yukia was in shock. Is that… Saïx?! She began to walk towards him, but didn't realize soon enough that the moon drives him nuts. She stopped short and stared wide-eyed at him, his blue hair frazzled around his muscular frame.

"S-Saïx-san?" her voice shook as he bounded toward her, pouncing like a wild beast upon her. "Ahhh!!"

Saïx slashed out at her, scratching every piece of her body he could find, ripping at fabric along with flesh. Blood dripped from fresh wounds on her body, staining the white sweater and the grey dress underneath. Maybe it was her strangled screams, or the scent of blood, but Saïx stopped just as fast as he started.

"Y…Yukia. Out. Get out of here, now!" He struggled to regain control of his body. Yukia looked at him, but didn't move.

"Do as I say!" he snarled. "Get out of here, Yukia!"

She moved to get up, but hugged Saïx instead. "You… you're suffering, right?"

Saïx snarled and huffed again, losing his grip on his control. "OUT. NOW, YUKIA!"

"NO!" she gripped tighter around his shoulders. "I won't leave you like this, or anyone else!"

As he lost control again, Yukia kept taking the blows and bled-bled until almost all her veins ran dry…

… and then the Sun came up.

Yukia huffed and coughed, spitting up massive amounts of blood. Laying next to her was Saïx, who was equally covered in blood, but had no wounds. Yukia was slipping in and out of consciousness, breathing shallowly- her ribs cracked with the effort of staying together. The crimson liquid that dripped down Saïx's body was thick with fabrics- both hers and his own.

"Why…" Saïx huffed. He slammed his fists on the concrete. "I told you to leave me!"

Yukia closed her eyes, and then opened them again, staring at the blue-haired Berserker with all her might. "I won't leave anybody… who needs my help."

Saïx sighed, getting to his feet. Picking her up, she almost fell apart in his arms. How many wounds have I given her? He walked towards the entrance to the Castle That Never Was, thinking of ways to explain to Xemnas what a beautiful power she possessed.

Axel and Roxas had been in a card game with Luxord and Demyx when Saïx walked through the door, carrying… Yukia?

She was bleeding all over, blood gushing out of wounds that were unbelievable large- and probably very painful. Her bones- they were poking out of places they shouldn't be, along with the ripped remains of her clothes. Saïx, however very bloody, was uninjured; not a scratch was on his barely clothed form.

"Yukia-chan?!" Demyx was the first to shout, and he ran over to her. "Wh-what happened? Saïx, who did-?"

"Move, number Nine." Saïx growled out to him, making the Nocturne shiver in fear and back off. "Yukia… made a mistake."

Roxas spared a glance at the poor girl, whom was probably warped beyond belief by now. Did Saïx just look at Yukia with… regret? He would feel sorry, if he had a heart. "Axel," he started "wasn't last night the night of the Full Moon?"

Axel stiffened. "Yes."

Luxord's features flashed to something resembling concern, and he placed his playing cards back down on the coffee table.

"I'm going to see The Superior."And with that, Saïx left the room, dripping with blood and other unmentionables.

Xemnas didn't expect a knock on the door this early in the morning, but if he could guess who it was- it was a pretty good chance it was Saïx. What he also didn't expect to see, however heartless he may be, was a blood-soaked Saïx and a mush ball of flesh and bone previously known as Yukia.

"Number Seven," he stared. "What happened to Vexen's Replica?"

"She tried to…" he coughed- a noise unfamiliar to Saïx's mouth. "Last night was the Full Moon, and she tried to… to protect me."

Xemnas almost wanted to laugh. "She's heartless, Saïx. And a Replica at that. It shouldn't matter what she does, because she has no real purpose."

Saïx looked emptily at Xemnas, as if trying to convince him otherwise.

"You are wrong, Superior." He clutched the barely breathing Yukia in his arms. "She does have a heart."

Demyx cried uselessly like a child, covering his face, and groaning involuntarily. He tugged on his hair, shaking his head back and forth.

"No, no, no…" he sobbed. "I told her she shouldn't get hurt again!"

"She was pretty beat-up when Saïx brought her in," Luxord flipped some of his cards in his hands. "Did she get sent on a mission with him?"

"Nah," Axel laughed "Saïx doesn't do missions, remember? He just bosses us around- like we're all dogs."

Roxas looked as if he was deep in thought, contemplating what to think about this.

"Roxy," Axel shook him. "Roxy, what's wrong?"

"I…" he shook his head. "She's strange. Last night was the Full Moon, and we all know that Saïx goes ape-shit on anybody and anything that crosses paths with him when he's gone berserk. Yukia probably didn't know this- and went to find him."

"No," Demyx's head shot up, a look of intense fear mixed with anger. "He wouldn't do that to her, right?"

"He doesn't care, Demy. He's just one of Xemnas's tools- like we all are." Axel put his hands behind his head.

"No." Roxas said out of the blue. "Did you see the way he looked at her? With sorrow, regret. He does care… like we all do."

They were all silent when they heard the sound of a head colliding with the door to Xemnas's office.

Saïx growled ferociously after he dropped Yukia, her body now lying almost lifeless on the floor. He wasn't expecting Xemnas to lash out at him like that, to hit him with such force. He now was bleeding from his head; the force from the blow had caused him to crack his head on the rough wooden frame of the door.

"Don't tell me," Xemnas said, voice laced with poison "if I am right or wrong. That is my job to tell you Saïx."

He got up and went over to Yukia, brushing hair out of her eyes and looking at the claw marks on her face.

"She's not like the others, Xemnas." He picked her up once again, going to the door. "She has something that makes all of us feel, as if we really did have hearts."

Xemnas sighed when he left and sat at his desk.

"This is pathetic… why do they all love her so much?"

A/N:

RAAAAAAWR.

Dude, this is like, over 2,000 words. :D

Thanks again for the inspiration, Clarilune- you're my most frequent reviewer! But I'm still waiting for other Duskies to inspire me, so I'll wait 'till the end to decide who gets to pick a song for the History!Ficlet. I'll take any requests you have, however.

;D

Hope you all liked this extra-long chapter!
