Part II

Chapter 5

–Hueco Mundo–

The arrancars second raid on human world was only a distraction, to kidnap Orihime, whom Aizen took interest in, because of her peculiar powers. While all those shinigamis were fighting, Urahara included, Ulquiorra invaded the space in between worlds and her disappearance was imminent.

However, on that time, when his goal was achieved, when those hollow-invaders were leaving the human world through the garganta, someone else entered the passage. The brown-haired boy who nurtured a scorching hatred for his father followed them occulting his reiatsu, lucky him, they didn't even notice his presence for their own negligence, the battles affected their senses and they could only feel vexed by the results.

In Las Noches, the four invaders of the human world walked through the corridors. Their images were reflected on the ground, Luppi was huffing about their battle, he was choleric, fussing about his loss. Grimmjow walked quietly, with his hand on pocket and a low gaze, he was reminiscing his last fight, when Ulquiorra impeded him from killing Ichigo.

He felt a strange sensation, like someone had been observing them for a while, and turned back calmly, frowning at the vague corridor behind him.

"Huh?" he stared at the place for some seconds, but the gray color of the ceramic was the only sight he could catch. And the vile shadows at the intersections of corridors.

"What is it, Grimmjow? Are you already missing up being beaten in the human world?" Luppi hide his vicious smile with his long sleeve.

"Hah?" the blue-haired arrancar snarled "Do you think you can mock me when you also got beaten up as badly as me, huh?" he provoked.

"Your…" Luppi frowned irritated.

"Ah, seriously, this is pathetic." Yammy scratched his head "Enough, we're going to see Aizen-sama. Let your brawl outside the throne room, I don't want to be punished along with you…"

"Tch." The former sexta espada grumbled in annoyance, averting his eyes from the others. He could swear he had felt a presence, but it was so faint and almost imperceptible he believed it was a misunderstanding.

What he didn't know was that at the end of that corridor, lurking in the shadows was the brown-haired boy that had took advantage of the arrancars raid to follow them when they went back to Hueco Mundo. Akira was covered by the black mantle Urahara had invented to occult reiatsu…

"It was a good decision to take this mantle with me… I'll have to apologize Urahara-san for stealing one of his belongings and thanks him, it was very useful…"

Akira thought, sighing in relief, touching the silk textured mantle he was using. Without that accessory, hiding his spiritual powers would be an impossible task. Determined he awaited the enemies vanish from his line of sight, but when he stepped onwards to follow them…

"Hm?"

There was a male voice behind him, he instantly swerved back, nervously searching with his eyes, until he identified a figure standing at the end of the long corridor. His eyes widened, and in a blink of eye, that figure disappeared. Akira's heart raced as he searched again for that person, then, someone appeared right behind him.

"Who are you? I've never seen you around…"

Stark, the first espada was scratching leisurely his head while looking at the boy with a raised brow. Akira was now unnerved, how? How did he arrive there? Akira couldn't feel his reiatsu.

"Ah, I see… An intruder…" his serious expression was aggravated by the eerie tone of his voice.

"No… I've finally reached here…" Akira's desperate thoughts made him sweat while looking at the enemy, ready to take his zanpakutou and fight.

"Oh… Is that a zanpakutou?" Stark's gaze feel upon the grip of Akira's sword. "Are you a Shinigami?"

His penetrating gaze was teeming with an uncanny and cold vibe that sent chills to Akira's spine and the boy gulped foreseeing a horrible fight right at the start of his invasion.

Throne room

After kidnapping Orihime, she was taken to the throne room, where many arrankars awaited. Luppi was indignant that a female woman had caused them so much trouble, but he stopped complaining after seeing her powers, then, Grimmjow Jaggerjack who had been demoted from the position as sexta espada killed Luppi to regain his position.

Orihime was saddened and felt incapable of going against them at that time. Her powers would be used for evil, but what she cherished most at that time were her friends, and as long as they stayed fine in the human world, she wouldn't have problems in obeying orders. Deep inside, she knew she was only a tool that would be discarded at any time, when they didn't need her powers anymore… Still, she tried to stand strong.

When she was leaving the room with Ulquiorra guiding her to her new bedroom in Las Noches, she caught a glimpse of the first espada, he was carrying a boy under one of his arms. Who was that boy? He was using a shinigami's uniform, her eyes were dazed for a moment as she tried to comprehend, but the cold and insipid voice of her jailer was heard, breaking her daydreaming:

"Woman, walk faster."

She hurriedly followed him, lowering her gaze in resignation. Her fists didn't even have the strength to close in a grip anymore… She didn't feel revolt or anything, maybe, if she passed time enough on that place she would become empty like those people too…

Entering the throne room was Stark. He yawned and put a hand over his mouth, then he looked around, there were many glances stationed on him, they were confused. He directed his gaze to Aizen who was sitting in the throne with his usual placid demeanor.

"Stark, would you explain to us what does it mean?" he demanded in a soothing tone, in a way it didn't sound like an order.

"Ah, so troublesome…" the lazy arrancar scratched his head and dropped the boy he was holding on the ground. "This one was invading Las Noches, it seems… I didn't know what to do with him, so I brought him here…"

"Invading…? Preposterous! How have this boy arrived here?!" Szayel frowned.

"He could enter here without being noticed…?" Nnoitra smiled deviously "Like a little insect…"

"Apparently, he was using it to conceal his spiritual powers…" he threw on the ground the black mantle Akira was using previously.

"Oh, this is…" Gin seemed amused "How did this boy put his hand on one of those?"

"Isn't it something from Soul Society?" Hallibel narrowed her eyes, directing her gaze to the three Shinigami.

"What are you trying to insinuate?" Tousen frowned, bothered by her comment.

"Was this boy alone?" Aizen broke the discussion before it ever began and switched the attention to Stark again.

"Yes, he was spying some arrancars… I believe he followed them when they went to the human world…" he guessed.

"Isn't he a Shinigami? How could he follow us without being noticed, huh?" Yammy contested.

"We've just explained, moron." Nnoitra responded annoyed "He has concealed his powers, weren't you listening?"

"But… Who is him, and why a Shinigami like him would come here on his own alone?" Szayel thought on the possibilities as his curiosity pinched his mind.

"I doubt Soul Society had ordered something, look at him, it's still a child…" the fifth espada gave a scoffing laugh.

"Hm… This boy, he resembles a lot…" Gin left the sentence unfinished as he stared to the fallen boy.

Before he could finish, an overpowering spiritual essence invaded the room, all the arrancars were unsettled, and their gazes turned at the unconscious boy. He had awakened and was trying to stand up as his powers leaked out of his body. He had some difficulties to stand, but when he got it, he noticed the attention was focused on him.

"Shit…" he thought touching his nape, it was still hurting from the surprised attack Stark used to make him faint. If he wanted to, the espada could probably have killed him with a single blow.

He analyzed his surrounding with his eyes, there were at least ten arrancars on the room, of course, not all of them were espadas, but he was clearly at disadvantage. His eyes directed to the throne and trembled when he met the disturbing sight of his father.

His eyes were transfixed as he stared at the cold and nonchalant expression of Aizen, who simply looked at the boy with an air of superiority. The only noticeable change on Aizen was the lack of his casual smile. His mouth was closed in a thin line.

"Aizen Sousuke…!" his rage consumed his patience, in a second, he was holding his zanpakutou, without ever bothering how many enemies where on that room, he leaped towards the throne.

It was obvious he wouldn't succeed; no one would let him lay a hand on Aizen, that was why the ruler of Las Noches could stay immobile on his throne while his subordinates took care of everything. It only angered more his son who was promptly trying to attack him.

In middle air, Akira felt a presence drawing near and instinctively avoided, if not for his wise decision, he'd be parted into two pieces now. The fifth espada looked at the boy, he had almost hit him with his enormous blade, but the brown-haired was cautious now.

"Tch!" Nnoitra spit on the ground irritated and smiled wickedly "You're fast, huh, boy?"

"…" Akira only narrowed his eyes giving a darker tone to the childish traits on his face.

"If you want to take the boss, you have to kill its subordinates first, right?" he joked, jumping to give another blow.

"This is not a game!" he protested.

Akira used his sword to defend this time, but he was being pushed back. He gritted his teeth after observing the delight of his opponent in fighting. He was disgusted, albeit he needed to end the fight fast, he still didn't have a plan. He breathed profoundly to calm down and closed his eyes.

"Huh? What? Are you giving up already? You won't arrive up there if you continue like this…" the foe mocked once more.

When Akira opened his eyes, they were fully determined, his hesitation and fear had disappeared completely and a blazing icy air filled the depths of his brown eyes as his reiatsu flowed out of his body. It was almost like his father.

"Hanketsu (pronnounce), Shigoku: thorn."

From his zanpakutou strands of a thorny metal expanded in a rush, forcing Nnoitra to step back to cut the strands. He scowled at the boy.

"That boy has a shikai…?" Tousen frowned thinking how outrageous it was for the boy to hold such power at a young age.

Aizen seemed to be unconcerned about the results since he believed the boy would probably die by the hands of some arrancar. Gin also observed the fight, though, more than the fight, he was interested on the reaction of his captain that had not smiled again until now. He was clearly bothered, he looked even bored, but, why?

"Captain, do you know him?" Gin peeked at Aizen's face to fathom something on his sly mind. "His reiatsu is very similar to yours, not to mention his appearance…" his smile enlarged "Is he a disciple you left behind or something like that?"

"Why would I engross myself with a child like him?" he simply answered cupping his chin on hand and watching the fight pacifically.

"Then, why is this boy craving for your blood like that?" he pointed at the fight.

"Who knows?" His voice was as vague as his eyes paying attention to the brawl on the room.

"They will destroy the room if they keep fighting here. It's unacceptable!" Tousen held the grip of his sword, but Gin interfered standing in front of him.

"Relax, Tousen. Captain Aizen hadn't said anything, right? When he feels the fight is over, it will be over. " the wretched smile of Gin only infuriated the blind man. He could sense the astuteness of the silver-haired through his words.

Meanwhile, the clash between Nnoitra continued, and the other arrancars also watched from the ground.

Akira drew a firm cut, but Nnoitra jumped and descended his blade to rip the boy apart, the boy gestured something with a hand and proffered:

"Sajo Sabaku."

Reiatsu braided yellow lines came out of his hand and enveloped Nnoitra, sealing his movements.

"H-huh?" he looked annoyed at the ropes binding him. "What is that?"

"Oh… Isn't that…" Gin was astounded.

"…." Aizen narrowed slightly his eyes.

"Where did this boy learn how to use this?" the third in command was vexed "It's a powerful kido, how did he know…?"

After stopping Nnoitra movements, Akira raised his sword, and used his shikai again:

"Hanketsu, Shigoku: heavy crush."

His blade became a heavy hammer, making Nnoitra apprehensive, when Akira finished the blow, a cloud of dust wafted from the ground that was broken by his hit. The boy seemed unsatisfied and grimaced in irritation after seeing his enemy had escaped.

The fifth espada had broken the kido chains binding him and avoided the hit, not completely as his right arm had a single scratch. He stared at the boy, annoyed and his mouth twitched.

"Do you need help against this child, Nnoitra?" Szayel provoked with a malevolent smile.

"Shut up! I'll end him now!"

The choleric arrancar dashed with fervor and gave consecutive blows that Akira defended skillfully, still he had difficult in dealing with his opponent for his heavy blows. In a moment of distraction, Nnoitra vanished from his sight and appeared right behind him.

"Humph… Did you really think you could win me only with this…?"

He braved and slashed the boy's back, sending him away with a kick. He was pleased to finally hit the child seriously. Akira was on the ground when the cloud of dust dissipated, he tried to stand and the enormous wound on his back hindering him.

"Is that all you have?" the quinta espada landed the cable of his blade on his shoulder and raised a brow "You'll need much more to confront Aizen, kid."

"This boy was very hasty coming here alone, don't you think, Captain?" Gin looked at his superior, trying to extract some kind of response, but Aizen was silent.

"If Nnoitra doesn't finish him with this blow, I'll be the one to accomplish this task." Tousen threatened.

"Nnoitra, don't play with the kid, it's pathetic. End his life with pride. That's 'love'." Zoomari scolded in his peaceful tone.

"Tch! I'll finish him when I want to…"

The fifth espada drew closer to the boy, feeling an immense hatred and desire to destroy that child that had injured his arm. He stopped when he saw the determined expression. Those fiery eyes, they remembered him of someone he also hated, Nelliel. His veins popped out and his temper became worsen.

"You…!" he jumped to attack, but Akira stood up and defended.

"You all are strong… You're right about my current level… I won't be able to win like this…"

"Huh? Did I hit your head too badly?" he sneered.

"… No…"

The flow of reiatsu around Akira suddenly changed, Nnoitra cautiously jumped back. His body reacted on instinct, if he was too closer, he felt that reiatsu would probably disintegrate his body.

"Ah… This power resembles a lot yours, captain… Even the monstrous quantity of power leaking out of that child…" Gin smiled worriedly "Is he even able to control that?"

"…. Probably not." Aizen had a faint smile this time, but his eyes were nowhere closer of enjoyment, he was upset.

Akira held his sword with both hands and let his uncontrollable reiatsu flow out, his eyes showed how defiant he was towards the quinta espada. The other espadas were also warned at that point, if something was going to happen, they would interfere. The boy seemed to be preparing to use some sort of ultimate move.

"What is this…?" Nnoitra frowned, confused for the first time.

"Something to end this fight…"Akira only smiled briefly, feeling victorious. "My full power..."

The next scene unfolded in front of the presents was astounding, they all were flabbergasted, even Aizen had a perplexed expression and his eyes widened when he listened to the next words spoken by his son:

"Ban-kai: Shigoku, Tsukuru (create)…"

"Time"
