Title – Filling the Void

Disclaimer – I don't own anything

Summary – Rukia and Ichigo were captured at Hueco Mundo. When they get rescued they find Rukia has been experimented on. They were trying to create a strong baby from a shinigami and shinigami/human. Rukia is carrying Ichigo's baby. ICHIXRUKI

It was windy. Very windy, and she was glad for the cloak her brother gave her. Renji stood by her side wearing a duplicate of the same scarf. She shivered as she sheathed her Zanpaktu back on her hip where Sode No Shirayuki rested. They were standing in a desert and mostly deserts were supposed to be hot, but this one was cold and windy and the dirt got everywhere. Her brother must have known this when he gave her the scarf's.

But it didn't matter, her friend was gone. Orihime Inoue. And Rukia had a debt to pay. Orihime saved her life and now it was Rukia's turn to save Orihime.

"Oi!" She called out to her orange haired friend.

"Rukia… Renji?!" he cried watching the ice slowly break and knowing exactly who's attack that belonged too. His raven haired short shinigami friend.

Ichigo, Chad, and Ishida had all gone without Rukia and Renji to Hueco Mundo. The two shinigami were forced to stay by their commanders.

"I was only commanded to bring you home, what you do from then on is none of my business." Byakuya Kuchiki said handing her two cloaks and turning to walk away without another word.

Rukia now stood staring at Ichigo with a confident grin. She was by his side once more, and this time with her brother's courage in her heart.

Rukia punched Ichigo hard in the face once she reached him. Renji followed with a swift kick to the poor teens head.

"What the hell!?" He shouted cupping his cheek.

"You left without us!" Rukia screamed, she was irritated.

"Yeah! Selfless prick!" Renji shouted above the cruel wind.

"Ah! Whoth this?!" A tiny little girl with greenish white hair poked her head out from behind Ichigo's leg and smiled a big toothless grin. Okay maybe a few teeth. She looked like a toddler and had a hollow mask on the side of her face.

Rukia raised an eyebrow at Ichigo and back down to the tiny girl.

"Ah, Rukia, Renji, this is Nell." He rolled his eyes at the little girl.

"Pleased to meet you Nell," Rukia spoke softly giving the small girl her hand.

The tiny toddler took Rukia's hand harder then expected and smiled, "Ptheased to meet you!"

"Now that introduction's are over let's head on in." Ichigo said looking at the dirty buildings.

Everything was happening so fast. The minute they finally entered Hueco Mundo they split up much to Ichigo's dismay. He thought it was the worst idea but Rukia fought with him, she said that he needed to stop worrying about her that she could take care of herself.

He tried to believe what Rukia was saying was true, but it just continued to bug him as he ran down the thin endless hallways.

"Ithigo!"

Ichigo halted to a stop at the familiar voice. He swirled around only to see a crying Nell running towards his way.

"Damn it Nell! What the hell are you doing over her?! You need to be safe outside!"

"I couldn't let you leave Ithigo!!" The tiny toddler cried jumping onto him knocking him off balance for just a moment.

He grudgingly took the tiny toddler with him unable to leave her alone as he continued to run down the thing hallways searching for Orihime.

They made a pact before they left. Everyone, they promised to come back alive. They had promised each other before all of them going on their separate ways. He was worried. It was itching the back of his neck. His friends weren't close to him so he could protect them and that made him worried.

Rukia got her powers back not to long ago, she was still freshly healed, of course he was worried. She was powerful, but her power doesn't match these Arrancar.

He paid close attention to their reitsu making sure to keep a close watch on his nakama's reitsu the most.

If he concentrated hard enough he could feel it run through his veins her heart beating in tune with his as he ran. She was running too it seemed.

And then he felt a reitsu not familiar. Someone strong, very strong.

"Ulquiorra." Ichigo hissed turning around, "Nell, get back." Ichigo said setting the toddler down. She did as she was told.

"So… we meet again." He spoke in that silky voice.

And he felt it, Rukia's reitsu flared at incredible rate.

"Kaien – Dono!" her heart fluttered. Her eyes must be playing tricks on her. Kaien – Dono was dead!

"Kuchiki…" his voice was just as she remembered it sending chills down her spin.

She killed him, as much as she'd love to see him standing in front of her well and alive she knew it couldn't be possible. And especially how he taunted her and how he told her to claim the heads of her team mates.

"Kaien – Dono would never hurt his comrades." She hissed.

The fight began. He flew at her but she blocked. The continued to throw attacks at each other, while he continued to throw taunts at her trying to throw her off guard.

This man was definitely not Kaien – Dono, especially not after her attack that revealed his face in the sunlight. He was a monster.

The final blow came, they both threw their most powerful attacks at each other. He was dead and Rukia collapsed.

Her breathing was ragged and she lay bleeding in pain on the floor.

"I can't die…" She whispered to herself, "I can't die, I have to save Inoue." But she could feel her body grow numb.

Everyone's faces came into view and she felt tears start to prickle at the corner of her eyes, "I can't die alone…"

But she was dying alone, she could feel Ichigo's reitsu flaring incredibly high. He was in a fight, he wouldn't be coming.

She closed her eyes trying to fight and stay alive, but just by keeping her eyes open was taking all of her energy.

She thought she was already dead when she heard footsteps. Heavy paced footsteps. She opened her eyes only to find her vision was blurred. She felt a sharp pain in the back of her neck and her eyes closed this time forcefully.

"Damn!" Ichigo was loosing energy fast. He was distracted. Rukia's reitsu was gone. He couldn't feel it anymore.

"Ah, pity, you're shinigami friend is dead." Ulquiorra taunted.

Ichigo hissed in pain as a blow to his head threw him on the ground.

"Icthigo!!" Nell screamed tears quickly springing to her eyes.

"Nell go to the other's!" Ichigo chocked out. He couldn't let Nell see this; she was just a baby after all.

Nell numbly nodded and ran desperately searching for help.

"Now, where were we?" Ichigo cocked that grin.

Ulquiorra was not impressed. He came at Ichigo with the final blow knocking Ichigo out cold.

"Hmph. Easier then I thought…." He sneered at Ichigo's prone form.

"You got them both?" Aizen said stroking Rukia's naked thigh.

Her body was laying on a stretcher naked and an Ivy tube in her arm. Any wound or cut on her body was gone. Orihime was forced to heal them both. Of course she complied with no complaint only that she wanted to know why her friends were laying unconscious on a stretcher. Ichigo was brought into the room not to long ago.

They were both unconscious and the experiments began.

"What do you think will happen?" Ulquiorra asked watching the experiments on the dark haired shinigami begin.

"I want to know its power between a human and a shinigami. Not just a human but a shinigami/human. An especially strong one. If we can keep them here long enough we will create the child and know its powers and strengths. We can use it as their downfall if we can get it to be strong." He smirked as the needles probed Rukia's skin for blood samples.

He was optimistic that this experiment will work.
