Part II

Chapter 6

–Breaking the Time–

"Ban-kai: Shigoku, Tsukuru (create)…"

"Time"

When Akira proffered those words a gigantic reiatsu covered the whole room, making it tremble, most of the presents had perplexed expressions, even surprise stamped on their faces. Gin's smile faded when he watched the scene. An intense light obfuscated their sights producing a strong wind and making some clouds of dust form from the previous crumbles in the room.

"Captain Aizen this is…"

"That little boy has a bankai?" Tousen frowned.

Nnoitra put his arms in front of his eyes to protect it from the light, but he could barely watch as a white smoke embroiled the boy's body. He did say "bankai", but what was his bankai form? Well, be it strong or weak power, he'd kill the boy instantly.

"So he achieved bankai, huh…?" Aizen narrowed his eyes and a devilish faint smile showed his true colors "What will it be?"

"Even captain Aizen is interested now… Scary…" Gin joked, but his attention averted to the place where the boy was as the smoke was starting to fade.

It took some seconds for Nnoitra to see clearly the silhouette standing amidst the smoke. It was definitely taller than the boy he was fighting. Then… How? A shock hit his mind when he saw the exact features of his enemy.

Akira was nowhere near the snot brat he was fighting against until now, he couldn't understand how, but there was a man on his twenties, right in front of him. He had a wavy brown hair, much like Aizen before coming to Hueco mundo; his brown eyes were gentle, and his smile had a serene and contemptuous tone at the same time while he held the zanpakutou that belonged to the boy.

"What?" was the only thing passing through Nnoitra's mind.

"Oh… Interesting, his power made him grow into an adult?"

Szayel, on the other hand, was marveled with such unusual scene, his heart was beating with curiosity, he had to pick that boy as an experimental subject.

"… Is that… His bankai?" Zoomari couldn't understand. There was something odd about his form. "He looks like…"

Beside his physical traits, another fact called their attention: his clothes were the same as the arrancars, namely, the same from Aizen who was sitting in the throne. Why? Was he really mocking them to that point?

"His reiatsu decreased…?" Hallibel furrowed her brows in an obtuse angle.

"No… He is occulting it…" Stark was also paying closer attention now.

Aizen's surprise attenuated when he saw that form, but it genuinely picked his interest, he had to admit the boy was above his expectations. Gin smiled slyly and commented:

"You seem to be enjoying the battle now, captain…"

"I'm only wondering if he will be able to put more effort into beating arrancars, though, I doubt he can attain this level of conquers with his current powers…" he diverted the topic.

The silver-haired stared at his superior for a second, and averted his gaze to the new stage of the battle unfolding. The grown-up Akira held his zanpakutou with one hand and looked at the fifth espada with some sort of arrogance.

"What's with this look, huh? Do you think you can beat me just because you've grown up, kid?"

"I've never said something like that… But if you assumed it, I presume you're afraid of me now?" his calm tone didn't even sound like a scoff, still, it got on the nerves of his enemy.

"I'll cut off this petulant tongue of yours!"

Nnoitra advanced to slash the boy, he was infuriated and his blows became sharper as he tried to hit Akira who only avoided it so smoothly it seemed he was playing. Their swords clashed again, the arrancar knotted his brows, exclaiming:

"Inore, Santa Ter-"

Before he could complete that, Akira's hand appeared in front of his face and a burst of blue spiritual power started to gather on the palm of his hand:

"Hadou 73: Soren Katsui."

"gah-"

That was the only sound the fifth espada could say before the burst of blue light struck him and his body was sent away, destroying some walls of Las Noches.

"Using kido without spelling the incantation?" Gin snorted "He's talented…"

"…" Aizen frowned again, slightly fazed by the situation.

On the following second after Akira sent away the fifth espada, other two espadas presents and Tousen pointed their blades to the man, surrounding him. His eyes scrutinized the three enemies ready to cut his throat and there wasn't a single hint of fear on his eyes.

"You're interesting… I'll study your bankai…" Szayel adjusted his glasses.

"You can't disturb the peace of Las Noches…" Zoomari frowned.

"Destroying the palace is unforgivable!" Tousen declared.

Akira didn't even blink when looking at them, to tell the truth he averted his gaze, uninterested on them as if they were not worth his attention. His eyes landed on the throne, where his father was still sitting, almost testing him with his eyes. His next move astonished the watchers again:

"Hadou nº 90: Kurohitsugi."

His reiatsu was oppressive and massive, causing the entire structure to tremble when the dark matter started to form, covering the entire room with a killing intent. Aizen only smiled and said some inaudible words.

The dark matter that covered the place disappeared revealing an unscratched Akira. It was a way of provoking his father using his favorite hadou to destroy the entire palace.

"Oh… You survived…" he looked at the three attackers who were surrounded by a strong protective kido made by Tousen.

The walls of the palace were all shielded by a powerful kidou. Akira looked vaguely at the translucent matter covering the concrete structure and narrowed his eyes, he recognized the force overflowing from it and casted a glance to his father that was watching him from the throne with a cynical and gelid smile.

"You've finally decided to barge into the fight too, father…?" he mumbled to himself, and a confident and condescending sneer formed on his lips.

His attention was draw to the fight again when Nnoitra that had been knocked out, leaped to attack him violently, he had already released his resurrectión, his face was the definition of wrath.

"That impatient idiot…" Szayel frowned.

Akira held the grip of his sword with both hands and, whilst he was being pushed back when defending the strike, he spelled another sorcery:

"Bakudo 75: Gochutekkan!"

Five white pillars appeared and pinned the fifth espada to the ground, he was impatient and fretted trying to get free from the spell. Akira looked at him from above, with a lofty and serious posture. Then, the brow-haired son averted his gaze to the side, Szayel quickly came to slash him, he defended and proceeded with his kidous:

"Bakudo 62: Hyapporankan!"

From his hand, bluish-white rods of energy came out and menacingly flew onwards, Szayel evaded with finesse, but Akira appeared right behind him using shunpo. He manipulated his sword to use a lashing-like cut on the octava espada's back, the pink-haired whirled back and defended, but his face was scratched.

"What a heavy sword, you should be more delicate… I hate the brute." He joked.

"I'm not interested on your tastes. Die." He jumped swirling in the air to produce a powerful cut with his blade, Szayel avoided, but again, he was hit, this time on his arm, damaging his clothes and skin.

"What a scary boy…" the pink-haired commented with a worried smile "He could cut past the hierro?"

When Akira would attack again, he was the one who was caught by surprise, Tousen had approached without giving any harbinger and attacked him from behind, he grimaced in pain as a long cut was opened on his back and right shoulder, and touched the wound, jumping away from the opponent.

"You've past the limitations! I won't allow you to cause more destruction on Las Noches!" his nerves were visible coming to the surface of his skin. He was an intolerant man and his justice needed to be enforced at any cost.

"Heh, I recognize you're strong, but do you still think you can win all of us, boy?" the octava espada grinned in a devilish tone as he prepared to attack together with Tousen.

"You're right… I acted smugly… If I want to fight against you, I should use all my might."

A creepy, dark smile appeared on the shinigami's lips as his eyes became icy. They had a drop of sweat on their faces, his face now resembled the person they feared most: Aizen. Why was that boy so similar? His appearance, his behavior and even his powers and reiatsu… Moreover, did he still have tricks under his sleeve?

"What's going on…? What's the source of his faith in winning?" Hallibel was vexed.

"Oh, looks like he will going to do something entertaining again…" Gin was captivated by the fight at the time.

Aizen merely glanced to his subordinate, concentrating on the battle after that. What would he do this time? He couldn't deny he was also curious like Gin, he wanted to know what his son had under his sleeves now…

Akira laughed internally seeing the perplexed expression on the faces of the arrancars, of course they couldn't predict he had another trump card after using his bankai. When he covered half of his face with one of his hands, they all felt a chill and their eyes opened as the mutual feeling of bewilderment invaded the foe's minds.

When he passed his hand in front of his face a white mass started to mold a mask, they frowned. Szayel was marveled, but none of the others felt the same, Zoomari immediately approached the enemy trying to cut him, but it was too late. He hit the ground, producing some smoke from the debris, but within the smoke a figure came out.

Akira had his face covered by a white mask with blue triangles under the eyes and blue strands on the left side of the mask. His eyes under the mask were gray, with a black sclera, exactly like vaizards.

Aizen's mood changed again, his mouth was closed in a thin line and his brows furrowed slightly in displease. Gin was flabbergasted, trying to understand what was happening, he was sure the boy was a Shinigami and except for Shinji's group he didn't have any information about other vaizard. Tousen also seemed to be oblivious to the boy, the case now was…

"Captain… Do you know something about this boy's hollowfication …?" he dared to ask in a cheeky and subtly concerned tone.

"No…" his voice sounded distant, his mind was also traveling far from that universe.

The silver-haired watched the face of his captain as he tried to create hypothesis about what he was thinking. It was impossible that Soul Society would accept a boy that could transform into a hollow, he knew it because they already passed by a similar situation in the past, and the vaizards had to run away before getting punished. Then… How could this boy be a Shinigami? Have he been hiding in a hole until now?

He got startled when the boy finished his transformation. Akira's voice changed, they couldn't see his expression, but his eyes were as sharp as before and more threatening.

"Behold, espadas." His tone was arrogant as he lifted his blade to point at the enemy. "I'll destroy everything at once…"

"You keep picking my interest. You'll be an interesting subject!" the octava espada unseemly personality started to show itself.

"Boy… Just what are you…?" Stark was utterly convinced he had some sort of connection with their current boss.

Akira didn't delay on transforming into reality his intimidations, a puissant spiritual power overflowed from within him, leaking to the ambient, causing a smooth trepidation. When Szayel jumped to attack him maniacally, he has spoken:

"Hado 91…."

Around him, thousands of pink points of energy appeared, the arrancars immediately understood the purpose of his attack.

"He will-" Stark's eyes widened as he saw the energy points drawing closer.

"... Senju Koten Taiho" Akira finished the spell.

The points of light descended like comets to eradicate everything inside that room, the barrier included. A dazzling light emanated and a deafening sound echoed through the desert of Hueco Mundo as the entire las Noches trembled with the confront.

Inoue who was on her room could feel the tyrannical power that made her body feel heavy. She turned to the source of the power instantly, with a fazed expression. Ulquiorra who had just left her on her room and was now coming back to his own room also felt the clash of powers, his brows united forming wrinkle and he stopped walking. Who could've done that?

.

.

.

Back to the throne room, everything inside the barrier was covered by the smoke screen. Some cracks started to appear and spread through the barrier until it broke into pieces, falling and disappearing into the air.

The ground within the barrier was destructed as most of the pillars inside the room. Above the pile of debris, Akira stood panting profusely, his spiritual power was still lingering around, and although his body seemed exhausted, he still had a lot of reiatsu at his disposal.

"As I thought… Using powerful kido on bankai is dangerous… Even if my powers can support it, my body isn't prepared as bankai is only temporary, also this hollow form is unstable… I'll have to see which side-effects will manifest on my body…" he thought.

His mask started to break apart, the shatters fell to the ground. His coolness was disrupted when he saw some silhouettes standing before his eyes. Szayel and Zoomari were wounded with burns all over their bodies, Tousen used a protective kidou, the higher rank espadas were unscratched, tough, both the first and tercera were holding their zanpakutous.

What really surprised the brown-haired Shinigami was the fact that his father was sitting peacefully on the throne. His eyes widened, there was a mix of vexation and scorn on his expression, he grinded his teeth scowling.

Gin and Aizen were protect by a barrier created by them, it broke like thin glass right after the shockwave of his powerful kido, but it still angered Akira. When he was about to throw his body at the throne and pick a fight with them, a shadow swiftly appeared on his side, it was Hallibell.

"I'm tired of this futile battle. Know your place, boy!" she drew a cut, he defended with difficult.

Before their clash prolonged, another reiatsu was felt, reverberating on the entire palace, this time, it was Aizen's. His face was petrified and he directed a frozen glance to his son. He stood up calmly, but it alerted all the arrancars in the room that shared the feeling of awe looking at their boss.

Akira looked at the man and opened his mouth to finally voice a protest against his criminal father, however, it was too late. Before his eyes could follow, his father had vanished from the throne and was already by his side with a hand firmly touching his shoulder.

"Fat-" before he finished, his father's voice sounded on his ears.

"Don't you think you've caused a great ruckus already? Or do you want me to give a lesson to an undisciplined child like you?"

There was a collected and extremely cold tone as he whispered in a low way allowing only them both to listen to. Akira's eyes widened and flickered as he gulped. That was his intention since the start? To make him fight, test his abilities and dispose of him when he got tired of watching his fight?

Aizen put a hand on the grip of his own sword, the tension only increased when he did that, many faces had drops of sweat rolling down. Would he liberate his zanpakutou, Kyoka Suigetsu? Before he could complete his attack, Akira's body quivered and he bended a little, someone else had attacked him from behind, perforating the middle of his chest, when he noticed there was already blood splatting on the ground and his senses went numb, making him faint completely.

Aizen's eyes narrowed as he looked at the perpetrator, the sly fox who accompanied him:

"Gin."

His voice was a maze that had more than seriousness imbued within it, and his subordinate wondered what could be it, since it seemed to have some disagreement on his boss' voice regarding his last action.

"Ah, sorry, captain Aizen, I only thought it would be good if you didn't need to stain your hands." He gestured trying to excuse himself. "Don't look at me like this…"

Their conversation was cut in the middle when smoke popped out of the boy's zanpakutou and his physical appearance changed, his body transformed back on his child-form. Nonetheless, his spiritual powers continued to leak out of his body.

"This boy…" Tousen frowned, holding complex feelings of hatred towards the young Akira. "Even without using his bankai his spiritual powers are…"

"He really caused a mess…" Gin sighed tiredly. "The question now is: What we will do with him, captain?"

Aizen glared at the boy at his feet not displaying a sign of compassion or even care for his own son and averted his gaze, almost disappointed. His steps resonated in the silent room when he left the place.

"Whatever." He had put a hand on the pocket of his overcoat "He is no more a threat, just throw him anywhere or kill him if you wish."

His disinterest on the matter was dismaying, the white-haired subordinate simply nodded and picked the boy by his clothes, he was much smaller than on his adult form, but his reiatsu was still dangerous.

"Wow, what a prodigy child… But you know, it's quite scary…"

Hallibel had a frown, wondering what they would do, and Stark that usually didn't get involved on troublesome matters also had some interest as he observed Gin's actions.

"We should've killed him when Aizen-sama distracted him." Tousen complained to Gin.

"Give him to me, I'm sure he will be a good subject!" Szayel madness was explicit on his face.

"Killing him now is love compared to what awaits him if he becomes a guinea pig…" Zoomari commented pretending to feel mercy.

Nnoitra that had finally released from the kido braved infuriated:

"Kill him! I'll kill him! That shitty brat!"

"Don't try to blame the others for your lack of competence. You lost because you were full of yourself to think clearly on your moves during the fight." Hallibel sheathed her sword.

"Don't try to kill him, I'll be doing my next research on him!" the pink-haired declared.

The debate continued and Gin sighed, there was a pool of blood forming on the ground around Akira. Should he ask Orihime to cure him, or should he let the boy die? Should they imprison him or should they throw him at the desert as Aizen allowed them too? To tell the truth, he too was interested on knowing which sort of relationship the boy had with his captain. Smiling keenly, Gin was enthusiastic about this new way of wasting his time. What would unfold with the presence of this invader on Las Noches?

Chapter 6/END

Aizen isn't a good father, right?
