Summary: Accidentally hollowized; an eight-year-old boy ends up in Hueco Mundo. It isn't long until he's under the reign of Aizen who soon finds out he can not only utilize his Espada but make an experimental army of hollowized children to eventually take on the Shinigami in the coming Winter War. After all, who could fight small children and not feel terrible about it? Certainly not the Shinigami.

Episode 1::. A Boy and his Brother


He couldn't remember what happened; not clearly at least. One moment he was in the park, the next was pure blackness; empty, like it had never existed in the first place. It wasn't long until consciousness returned, cerulean eyes fluttered open tentatively to stare up dazed at the perpetual night sky. His fingers twitched, then closed around a lump of sand underneath him. At this point, he was more than confused; it hadn't been late when he left and he was certainly nowhere near a beach.

Sitting up, the small framed boy glanced around. His sandy hair had a layer of white sand coating it like fresh snowfall. As his eyes darted back and forth, he finally noticed the pair of emerald green ones staring back at him; completely emotionless. However, the observer had little preparation for the coming sudden outburst.

"Brother!" The boy cried out, eyes widened and his look of confusion replaced by a toothy grin. In mere moments he was on his feet racing towards the stoic man who promptly side-stepped to avoid the physical contact the boy was trying to initiate.

"You are mistaken; I am not your brother," The man told the boy, completely unmoved by the crestfallen expression that had quickly taken over. "You are...intriguing. Lord Aizen might have a use for you."

"Huh? Aizen, who's that," came the inquiry, curiosity filling the child's bright orbs. Then he seemed to realize something and his smile returned. "I'm Cael. Well, Kaelan Mikami but I just like Cael. What's your name, and what time is it? I have to go home soon or else my nanny is gonna be mad at me."

The man might have rubbed his temples in an irritated fashion had he possessed any emotions. However such trivial things were beneath him and he merely turned and began to walk away. Humans were irritating things, especially the young ones. He probably would've left the boy to the rest of Hueco Mundo had he not been attracted to the most peculiar phenomenon; a reiatsu spike that rivaled his own for only the briefest of moments. Currently the boy's reiatsu wasn't even notable, barely existent if anything, but the spike had been enough to gain the attention of nearly all of Las Noches.

"So, where we goin'?" Cael's chirp interrupted his thoughts and he looked down to find the boy peering up at him.

"Las Noches. Lord Aizen wants to see you."

"Me," came an incredulous reply. "But how come? And you never answered me. Who's Aizen and what's your name?"

"My name is none of your concern."

"Hey that's not fair! I told you my name," Cael cried out indignantly.

"Lord Aizen, is just that; Lord Aizen. You will address him as such and when he tells you to do something, you do it without question," The man continued on, ignoring the child's outburst.

"Oh...sounds like my nanny then."

Finally Cael stopped speaking, silence surrounding them as they traveled. He was not in any particular hurry. Even if he was, he was reluctant to touch the human and was unsure of the effects using Sonido would have on the child. Lord Aizen wanted him back there alive and unharmed; it wouldn't do to disobey Lord Aizen's orders.

White buildings rose high above them and they soon entered an area surrounded by a dome. Instantaneously, the dark night sky turned to a bright sunny day. Cael marveled at the sight silently, taking in his surroundings. Within the main building, winding hallways left the boy feeling lost and he walked closer to the raven-haired man leading him. Eventually they paused outside of a closed door, one of many lining the white hallways, before entering.

"He's busy," came a sly voice. A silver haired man with a fox-like grin met them inside. Though his eyes appeared shut, he peered down at the small blond child beside the Espada. "Keep an eye on him for now Ulquiorra. Lord Aizen will meet him later."

It was unusual for Lord Aizen to not want an immediate report after a mission; even if he did seem to always know what had happened without being told. However, he was not one to question his commanding officers and promptly turned back around silently wondering what he would do with the human until then. How did one care for a human, a juvenile at that? Thankfully enough it was old enough to communicate fairly well, else he would be at a complete loss but that didn't make his job any easier.

More white, winding hallways were all that met Cael's eyes and he was beginning to feel like he was trapped in a maze. The idea was both exciting and frightening to the eight-year-old. His mind filled with questions as they went. It didn't help that his leader wasn't speaking. Well he could change that; it was getting too quiet anyway.

"Where we goin' now?"

"My quarters. You will remain there under my care until Aizen wants to see you."

"Quarters? You mean like money? We're going to money?"

Ulquiorra halted in his tracks, staring down at the child. Though his expression did not change, he couldn't fathom what possessed the boy to gather that from his brief explanation. Were human children really this unintelligent?

"No. Quarters as in my room." The dark-haired man sighed. It was ridiculous he had to even explain it this far.

"Oh. That's a bedroom silly. Quarters are money that you buy stuff with. Like candy and ice cream. You're funny; I like you," Cael chattered on much to Ulquiorra's dismay.

There at the end of the hallway was the door they stopped at. It looked like every other single door in the place; all white, white, and more white. Desperately the shaggy-haired child wanted his crayons so he could make the place colorful like his coloring book.

"This is where you will stay. Under no circumstances should you leave this room until I come to get you myself. Do not make a mess and do not be loud."

Cael dropped his gaze to the ground. Ulquiorra sure sounded like he didn't want him there; but then why was he being so nice to him? Most people just ignored him even if he tried to talk to them. He looked just like his big brother too but a lot older. Mustering up the courage to take another glance up at the older male, he was pushed inside the room and the door was closed behind him before he could get out another word. Looking around, the room was practically barren. A small desk, a couch, and a table with a seemingly unused tea set were all that filled up any of the space inside; the rest of it empty.

Wondering what to do now that he was confined to a room with literally nothing in it, he plopped down on the couch and swung his legs. For a few minutes he simply looked around the room before getting up to investigate the area in a more hands-on manner. Despite the instructions not to make a mess, Cael was touching everything in sight; picking it up, turning it around in his hands before putting it down again, running his hands across the wall, the couch, the table. After he'd gone through every object and surface in the room he climbed back onto the couch and laid on it upside down, dangling his head off where his feet should have been. The room definitely seemed more interesting this way than right side up.

It didn't take long for him to grow bored, and dizzy from the blood rushing to his head, and he flopped around several times to get more comfortable. Deciding he really didn't want to stay stuck in here, despite Ulquiorra's command, the energetic boy scooted off the couch and to the door. There was no one in the hall, so he closed the door silently and went to explore. If he couldn't go home yet, he might as well have some fun in this new place.


This has been on my mind for a while now but I had done little more than dribble out tidbits and certain scenes. Now that I have a clearer idea of where I want this to go, I'm putting up the first chapter to see how the rest of you feel about it. Constructive criticism is encouraged.
