The Rebirth In Bleach
Rukia

A few minutes before -

unknown POV -

"Barrier Squad, what's your status?"

A young voice sounded to the mic. He had dark gray eyes and spiky black hair that reached his shoulders. 

He was wearing a standard academy uniform with his sword attached at the back. A '69' tattooed on his left cheek and wearing a necklace.

This young man was Hisagi Shuuhei, a relatively famous senior, who had failed the exam twice but due to his efforts was known as a sitting officer in the future. He was the one in charge and led the new students to their training.

They had just finished when he decided to contact the barrier team

"Hey, Reply!"

He began to get a bad feeling due to the lack of response.

"What's up, barrier team?! Can you hear me?!"

"Hey, answer me!"

"Hi!"

Not getting an answer, his classmate next to him asked,

"What's wrong"

"Something went wrong, no one from the barrier team responded"

"Gagi-kun!"

Hearing this, he also turned around and what he saw shocked him.

A giant hole stood there and swept its claws towards his teammate piercing right through his body.

"Yahoo!!!"

The screams of the new student made him come to his senses from a daze as he unsheathed his sword.

His classmate next to him shouted as he dashed forward to attack.

"How dare you kill Kanisawa!"

Hollow, seeing this sweep his claws and throw the girl's body to the side and once again sweep his claws at his attacker. Hisagi had just seen his friend die right in front of him.

'Damn it, how can a high class hollow get here'

"New student, run!"

Saying this, he took out the receiver and started contacting Soul Society

"Soul Society, ask for help. This is sixth year student, Hisagi Shuuhei. Attacked by a high-level Hollow at the point of life world no.1026 northwest, mark 2128..."

As soon as he said this, he saw the hole filling the reiatsu ball and shooting it towards him. Fortunately, he could only avoid it. However, it was only the beginning of true despair.

No matter how he attacked, he could not do any damage to the hole. Before he knew it, the hole had scratched his claws and scratched his right eye, leaving behind three long scratch marks. He was blinded with one eye.

The hollow this time increased the number of claws on one hand and directly attacked him. Realizing that he was unable to block it, he prepared to fight to the death.

Suddenly, out of nowhere, three figures appeared blocking the claws from three different directions.

"You guys…"

The one who answered was a young man on his left. She has blue eyes and shaggy short blonde hair whose bangs are just above her left eye. He wore standard academy clothes for men.

"Our deepest apologies, we disobeyed orders"

"We came to save you, so just ignore it, okay senpai?"

Lastly, on his left, covering the claws coming from below was a petite girl with brown eyes and black hair tied up in a pig's tail at the base of his neck. She wears a standard academy uniform for girls.

After the three of them pushed out their claws, they took out both of their hands and shouted

"" "Oh my God! Masks of blood and flesh, all creation, flapping of wings, you who bear the name of Man! Hell and chaos, sea barriers soaring, marching south!"""

"""Hakudo #31, Shakkaho"""

The combined strength of the three was able to push the hole backwards, enough for them to escape.

Escaping them questions why a high-level hollow can get here unnoticed and the only answer is that he can hide his reiats.

 While turning, they knew that they would not be able to defeat such a hollow and could only wait for help from Soul Society.

However, this time they really felt desperate.

A distortion occurred in front of them where dozens of high-level holes appeared. One after another they appeared and slowly surrounded them as the students slowly lost hope.

"Many of these big holes ..."

"Impossible"

"It's not real.this.no.I don't want to die, I don't want to die"

The blonde seemed to flinch while the girl had a look of despair in her eyes and despair inscribed with bold letters on her face. Only Hisagi and the redhead had some sort of fighting intent as they looked around.

The holes were slowly creeping forward but suddenly everything shook at once as an intruder flew over them. The screams of the garuda attract the attention of the four students. The students and Hollows were all staring at the white eagle circling around them.

Hisagi looked surprised at the new intruder,

"That's ..."

He had a faint idea of who was coming and started to look around.

Suddenly, footsteps rang out as another intruder walked behind them. The intruder did not say anything and only looked at the four students.

""""Hearts""""

Itsuki gave a glimpse into the hole when he got a sudden boost. After fully sheathing his sword, he spoke

"Omae wa mou shindeiru"

"Dani!"

Suddenly, all the holes exploded into dust when Itsuki stopped talking. Don't get me wrong, the one who shouted after it wasn't a hole, it was Renji in front. Looking at the person who was shouting, Itsuki thought to himself,

'Don't yell that if you're not the target'

You can't blame Renji, he was too surprised to see a hole that looked so impressive was suddenly defeated in an instant.

"Who exactly is he?"

Renji spoke as the others looked on with admiration. Hisagi retaliated

"Raijuu of Soul Society, Captain of the 2nd Division and Head of Onmitsukido, Minamoto Itsuki"

"Itsuki-sama"

A soft voice sounded from Hinamori as Itsuki was thinking about herself. He's fanboying inside. The group was expecting some kind of words of consolation, but all they got was a cold gaze that froze when he reached them. 

They could swear they saw ice flowers blooming around him as he walked.

"Oh, looks like I'm a step late"

Another voice sounded. Hisagi turned to look at the newcomer, both newcomers.

"Captain Aizen Division 5! Lieutenant Ichimaru!"

"It looks like Captain Minamoto took care of the hole"

Itsuki just looked towards Aizen and stabbed his sword into the air and turned it around. Senkaimon opens with Itsuki coming in first. The students looked at each other and followed behind. As they walked past Dangai, a cold voice sounded,

"Most of your classmates survived"

And back to silence.

They know that Itsuki is not good at talking and they follow him. Aizen, who was behind them, also did not speak as he maintained his usual harmless smile on his face while Gin had his usual sarcastic smile.

Not long after they left and a fourth member came to check their wounds. To the surprise of the four was the number of women looking in their direction. The children became delighted but then cold water was poured over them in the form of Hinamori's voice.

"Don't be arrogant, they don't see you"

This made them realize that they did not see them or Captain Aizen behind them, but rather at their savior in front. Itsuki turned around and gave them a final look before disappearing from their sight.

It was night time in the real world and with the circumstances being quite dark, it was difficult to see Itsuki properly, but now they could get it. The three boys were shocked but then depressed while Hinamori's eyes started to shine.

Aizen also left while talking to Gin,

"Gin, did you see it?"

"I don't"

"I don't either"

'Minamoto Itsuki, how much are you hiding'

This event swept over Seireitei because it was extremely rare for this situation to occur. The last time it happened was about sixty-six years ago, when Itsuki was undergoing her training.

Itsuki could not be bothered about this as it simply produced more documents and gave Yamamoto an explanation of the events that took a long time. Soi Fon could swear a black aura appeared around Itsuki and a faint murmur could be heard,

"Death to documents, death to documents, death to documents, death to documents ..."

He had never seen Itsuki so scary.

Right now, Itsuki and Byakuya had just finished sparring when Itsuki summoned Byakuya to the side.

"I think I've found Hisana's sister. Seeing someone exactly like him"

Byakuya was very surprised by this revelation because he and Hisana had been looking for him for years. This time, he used his authority as a captain and had obtained some pointers but was still deadlocked.

In the anime, Byakuya has become a captain after he adopts Rukia, roughly, forty-nine years before the main plot. But with the presence of Itsuki and his spar, Ginrei has given him the title of captain before. 

Although it was earlier than usual, it made no difference if Rukia was discovered now or later. He will only spend one year in the academy and will directly join the Gotei 13. It was time when Byakuya found him.

Byakuya then invites Itsuki to come with him but refrains from telling Hisana, she wants to surprise him. She still died because she was not worthy enough to be his sister. 

So, ever since she could remember it, Hisana always asked Byakuya to take her sister as her own and adopt her.

First, Byakuya wanted to see it, what character he had. Although it was Hisana's sister, if her character was bad, she did not want Hisana to meet her. 

This might be detrimental to him because he might think it was his fault that he ended up like this. But then it hit him, wouldn't he feel guilty for causing his sister's death if he had never met her.

Byakuya is an egg between a rock and a hard place. He could only hope that his character was good enough. And, boy oh boy, does he feel relieved. Itsuki could swear he saw tears of happiness flowing in his eyes as he looked at the report.

Byakuya then immediately brought the housekeeper and walked over to the academy.

 This time the Seireitei women made their dreams come true when they saw Byakuya and Itsuki together. The old housekeeper, however, was not having fun.

He could feel irritated eyes piercing through him as he walked beside the two captains. Seeing this, the old housekeeper shrunk his neck and tried to minimize his presence. He knew what they were thinking but the voices could not be stopped,

"What did the old misty do..."

Many other harsh words were quietly thrown out as the man grew even more miserable. Does it seem like I want to be here?

Fortunately, the academy arrived, and they entered anonymously. The headmaster was very friendly because great people had entered the academy. After realizing Byakuya's intentions, they are taken to a room where Rukia will be summoned.

Not long after that, Rukia came in.

"I'm in"

He looked up to see some foreign men and a pair of familiar eyes.
