Disclaimers: Bleach certainly doesn't belong to me. Believe me, if it does, I woud know.

Warning: Shonen-ai/Yaoi(probably)

A/N: I was reading the manga till chapter272 and wants more. When I was typing this story, I was thinking if there is a royal family in Soul Society, why can't there be one in Hueco Mundo (the Hollow world). So here you are!

"Then we have a deal, Aizen-sama."

Aizen opened his eyes and stared out the windows to the moon outside. It's a wonder how there is a moon in this vast desert land. "The time is here."

Right at that moment, all the hollows and arrancar in Las Noches felt the disturbance in Hueco Mundo.

ooooooooooooooooooooooo

"It seems that I overestimated you. Your evolution didn't meet my expectation after all. It's the end. If you can still move despite your condition, then leave Hueco Mundo immediately. If you can't move, then die." Ulquoirra turned and walked away. "Your journey ends here, shinigami"

Suddenly, there was a discharge of huge reaitsu coming from behind him. Ulquirro turned and saw a sight he would never forget.

"You're really useless, Ichigo!" White substance started to appear and connected together on Ichigo's face. Soon, a Hollow mask not unlike the one Ichigo wore before covered half of his face. The transformation was still happening. "Let me show you how to fight!"

H.Ichigo slashed his sword. "This is how you fight!" As the black-coloured getsu gatenshou flew in high speed towards Ulquiorra who dodged it, H.Ichigo disappeared and reappeared behind the arrancar and slashed him.

Blood gushed out from the wound. Ulquirro's face showed his shock. He knew that the shinigami wasn't supposed to be able to move, let alone fight. Yet, Ichigo was stronger than before. The wound in his chest had also stopped bleeding; and the still-forming mask. Was he truly one of them? He had no more time to think as the second attack came. Drawing his own soul cutter, he prepared to release it.

"Stop!"

Both H.Ichigo and Ulquiorra turned towards the commanding voice.

"Aizen-sama," Ulqiuorra bowed respectfully and sheathed his soul cutter.

On the other hand, H.Ichigo prepared to continue his battle with the new-comer. He had never felt excited as he felt now in the presence of the former captain. His blood was boiling for battle. "Getsu gatenshou!" The black aura raced towards Aizen with a higher speed than before.

Aizen stopped it with only two fingers and destroyed it by snapping it. The aura dispersed to reveal to him the shocked and angered face of H.Ichigo. A smirk tugged at his lips. He raised his hand and gave a signal to those behind him.

Zaeruappolo came in dragging with him the unconscious Abarai Renji and Ishida Uryuu followed by Haribel dragging Chad and Gin carrying the body of Kuchiki Rukia.

H.Ichigo could only stare at the nakama of his King. He could feel the rain in the inner world falling. Slowly but surely, his King started to fight him again. Ichigo peeled the mask away from his face with a loud screech. "What have you done to them?" At first, he thought they were dead but then realized that Chad, Renji, and Ishida were only unconscious. As for Rukia, her reiatsu was so weak she was on the verge of dying.

"Ku…rosaki-kun?"

At the sound of his name, Ichigo turned his head. "Inoue…"

Tears filled the eyes of Orihime. She covered her mouth with her hands. As much as she wanted to rush over to help Kurosaki and the others, she was very much aware of the silent warning coming from Grimmjow, who was standing behind her.

Ichigo gave the girl a smile. "We have come to save you, Inoue…"

More tears filled Orihime's eyes. "Why? If you hadn't come, none of you would be injured."

"Because you are our nakama." Tightening his grips on Zangetsu, Ichigo prepared for battle. He needed to save his nakama.

"Don't make reckless move, Ichigo-kun," Aizen warned with a gentle smile on his face but there was nothing gentle in his eyes.

"Please let them go," Orihime begged.

"Inoue!" Ichigo tried to stop her. He had a feeling he knew what she was going to say.

"I will stay here willingly and work for you."

Aizen chuckled. "It was never about you, Orihime."

Orihime was shocked at the new revelation. "What?"

Ichigo however was pissed off. "Then why did you kidnap her?"

Aizen turned his gaze towards the shinigami. "Kidnap? Be careful, Ichigo-kun. I had never kidnapped her. She came willingly, just like you."

Ichigo glared at the hateful face. He did not catch the underlying meaning.

Orihime's eyes widened. "It's not me…"

"Ahh…You finally understand. You're only a decoy, Orihime. A decoy to get Ichigo-kun to step into Hueco Mundo willingly."

"Then…all that you told me…"

"Were all lies. They were believable, weren't they? I have never needed you to unseal Hou Ryoku. Why should I when I will have its owner here to purify it all the time?" A cruel smirk changed the gentle face of Aizen into one of cruelty.

"Ow…ner?" Orihime turned to look at the confused Kurosaki. "Kurosaki-kun?"

"You're quite a bright one, Orihime." Aizen took a step towards Ichigo slowly.

"Hey! I don't understand a word you're saying," Ichigo finally couldn't stand the riddle and spoke up.

"That's not…"

Aizen cut off what Orihime was about to say. "Possible? I can tell you right now, it's the truth. Kurosaki Isshin used to be the captain of 11th division."

Both Orihime and Ichigo's eyes widened.

"The day of Ichigo's birth, everything changed. Hou Ryoku appeared by his side. Realizing the danger the stone represents, Ichigo-kun's father entrust it to Urahara and took him away from Soul Society. He disappeared with you and none in the Soul Society could find him. If it wasn't for Kuchiki Rukia, both your father and you would still not be discovered until today, Ichigo-kun."

"You're lying! My father is perfectly normal. He couldn't even see the spirits," Ichigo denied.

"That's because he lost his shinigami power as the price. He should have regained it by now since he did not need to conceal your location anymore."

"Then what do you want with me?" Ichigo yelled. "I will never unseal the stone for you. If it's really supposed to be mine, return it to me, you asshole!" Ichigo brandished his sword and attacked Aizen.

Aizen stopped Ichigo's attack as easily as that day in soul Society. Securing Ichigo in place by locking his hands behind his back, Aizen said, "I made a deal with the Vast Lords. They would obey me in exchange of you."

"What the hell are you saying? I'm not that easy to kill!" Ichigo yelled while still struggling against Aizen's hold.

"Kill?" Aizen chuckled. "You misunderstand, Ichigo-kun. No one wants you dead here."

Stunned, Ichigo stopped his useless struggle. "What…"

"Don't you want to know, Ichigo, your own secret? Why are you born with Hou Ryoku? Why do you have Hollow in you? Aren't you curious at all?" Aizen asked.

Ichigo did not reply. What could he say? If he said no, then that would be a big fat lie. If he said yes, would Aizen really answer him honestly? Ichigo shook his head. What the hell was he doing? He was here to save Inoue and the others.

"I will let your friends go back to the human world and I will answer your questions." Aizen released Ichigo.

Ichigo narrowed his eyes. "What's the catch?"

"You have to stay here."

"No, Kurosaki-kun," Orihime protested. "You can't tru…Ouch!" Grimmjow's hold on her hands tightened until it hurt.

"Let her go!" Ichigo screamed at the arrancar.

"Make your decision, Ichigo-kun. Kuchiki Rukia would not be able to hold on for long," Aizen warned.

Ichigo hesitated only a second. A glance at all his nakama, he knew that he was cornered. "Fine. Let them go."

"No!" Inoue protested despite the pain. However, a stubborn look on Ichigo's face told her that he would not change his mind. "Once again I have caused you trouble, Kurosaki-kun," she muttered in a very low voice that only her could hear.

A few seals later, a door opened. Under Aizen's command, Ulquiorra sent the four intruders back to human world. As soon as his job was done, he returned to Hueco Mundo. There were too many questions in his mind and no answer. The two most important ones were: who was Kurosaki Ichigo and how did he fit into Aizen-sama's plan? None of them Espada knew of any of this before this incident. Gin and Tousen probably knew but neither of them would answer any question. The only option was to remain quiet until Aizen-sama deemed it the right time to tell them.

ooooooooooooooooooooooooo

Orihime stared at the disappearing door forlornly. "Kurosaki-kun…" A moan reminded her that she had to save Kuchiki-san. Her fists tightened in determination.

ooooooooooooooooooooooooo

"Your friends have been returned back with no further harm," Aizen told the orange-head boy.

"I want answers now!" Ichigo demanded.

"You are in no position to demand answers from Aizen-sama," Haribel rebuked.

"It's alright, Haribel. He is Prince after all," Aizen dropped the bombshell.

"What are you talking about? Don't talk in riddles. I won't understand." Ichigo glared at the former captain.

"Like I said, I made a deal with the Vast Lords. They will obey me if I bring them their prince," Aizen said calmly.

"What prince?" Ichigo asked, still confused.

"You."

Only a simple word from Aizen's mouth turned Ichigo's world upside down. "What?"

"Hou Ryoku chooses the Prince of Hueco Mundo. It chose you. If it wasn't for the interference of your father and Urahara, you would have been raised here and ruled over this world."

Ichigo stared at Aizen unable to move his mouth.

"There had only been two Princes before you. Neither of them survived over three years. You're the first one to live to teenage years and still going strong. Do you know that all Princes of Hueco Mundo are born as an Arrancar?" Aizen dropped another bombshell. He was aware of the shocked state his subordinates were in but he was only focused on Ichigo's reaction.

Ichigo's eyes widened. Born Arrancar?

"Yes, Ichigo-kun. Your ability to transform into a hollow even though you're supposed to be a shinigami is due to your birthright," Aizen confirmed it.

"I am not an Arrancar. I am a substitute shinigami," Ichigo denied.

"Really? Then what is that Hollow mask? Something you buy in the shop?" Aizen mocked.

Ichigo had nothing to say to that. He did not want to admit it. "What is it you want from me? I get the Prince thing and the deal. What is your motive?"

Aizen smiled. "There is only one thing I have been after and that is POWER!"

ooooooooooooooooooooooooo

Ichigo was escorted to a huge elegant room. He sat on the bed, contemplating. The more he dwelt on what he had found out, the more confused he was. It did not seem to connect smoothly – what Aizen had said. Something was off with the explanation.

"If I were really the Prince, then why would the Vast Lords still obey Aizen once they have me?" he muttered. He did not think that someone as sly as Aizen would miss this possibility.

"That's the question I asked them as well," a voice said from behind.

Ichigo swirled to stare into Aizen's eyes. He was immediately on alert for any possible attacks.

"They offered something to me." Aizen smiled.

Ichigo had a bad feeling about this.

"They offered you to me."

"What do you mean?" Ichigo finally asked. As if he would obey Aizen just because the Vast Lords said that he had to.

"This." With that, Aizen pulled the boy to him and kissed him fully on the mouth.

For the first two seconds, Ichigo was frozen. Shock had consumed him until he could not move. "Mm…Wh….mmm…" He opened his mouth to voice his shock only to have Aizen's tongue plunged into his mouth. He tried to push him away to no avail; it was like a child pushing at the thick wall of the safe.

Aizen ignored the boy's attempt to stop him. He continued to taste every cavern of Ichigo's mouth until he had to pull away for breath. By then, the boy had stopped struggling and was breathing heavily when he withdrew. Aizen licked his lips. "I have never imagined you being this tasty."

"Wha…" Ichigo's feet collapsed under him. If it was not for Aizen's hold on him, he would have fallen on his face. "What have you done to me?" he asked weakly. "You sucked my reaitsu out of me," he realized.

Aizen smirked. "You have an almost limitless supply of them and it's still growing. By the time it stopped, you would probably have a bigger supply than me." Aizen carried the orange-head boy and deposited him gently on the bed. "Your father placed a seal on you when you're born. He had only intended to conceal you. He never knew what he did saved your life. Your soul would have broken if it had to deal with your reaitsu all the time, like the two previous Princes. It is rare to find a soul strong enough to sustain such rapid growth. Your reiatsu grew all this time in the sealed state but it did not harm your soul as all the force was directed at the seal. As you grew up, your soul had gotten used to the enormous reaitsu. However, the seal was ripped away when Kuchiki Rukia's zanbakutou entered you and you became a shinigami. Soon, you would feel the pressure of your growing reaitsu. When it is past the limit, you would die like the other two Princes."

Ichigo was silent when he heard this. He did not know whether he should believe Aizen or not.

"The Vast Lords came to a solution. Since I am one of those rare souls that could withstand such enormous reaitsu, they offered me the position of the King of Hueco Mundo. I only have to help you with your problem once in a while. It was to my advantage more since it means that I would have an endless supply of reaitsu from you."

"Even if what you told me was true, what make you think that I would comply with your plan?" Ichigo was still too weak to move, but that did not mean he had to take this silently.

"That's the ingenious of my plan. I had figured out a way to tie you to me. Your soul is tied to Hou Ryoku ever since you have been chosen as the Prince. Even in its sealed state, the tie is still strong. As soon as it is activated, the bond will grow. I had found a way to bind Hou Ryoku to me. Now, it recognizes me as its Master, which means…." He left the sentence unsaid.

"I will not be controlled by one stupid stone," Ichigo snarled. His strength had rapidly returned to him. If he had taken the time to examine it, he would be surprised at the speed his reaitsu recovered. Was it due to him being in Hueco Mundo?

Aizen pinned the boy to the bed under his strong body. "To me, you are only a fledgling. Stop struggling against your fate; it was temporarily diverted when your father took you away but it has been sealed the moment you met Kuchiki Rukia." He lowered his head and kissed the boy again. "From now on, you belong to me." He couldn't seem to get enough of the addictive feeling of Ichigo's reaitsu merging with his own in his body.

The end (or to be continued...)

A/N: I do not know yet whether I want to make this a oneshot or continue it. So, tell me what you think and I will consider. By the way, I truly love this pairing coz I think Aizen would be one possessive lover and he has a sadistic side as well. Now, review time!
