The Rebirth In Bleach
fusion

Itsuki stood behind Black Itsuki as it was cut in half. Before Itsuki black completely disappeared, he threw both of his zanpakuto to it.

 They put themselves right in the middle of the two halves as Itsuki black started to disappear. A formation appeared beneath them that was filled with unknown and ancient runes.

Itsuki has come up with a theory. Ichigo Hollow has become a zanpakuto spirit. So, since he could become a zanpakuto spirit, he should be able to strengthen it. Their shinigami and zanpakuto are one entity, so strengthening one will also strengthen the other. It was just a theory so he tried it now, he didn't know the chances of his success.

Itsuki didn't want to have a temporary increase in strength, he wanted a permanent one, so here's the result. 

Looking back at his zanpakuto, it seemed to work because he could feel his zanpakutos becoming stronger. The raw strength of the hole seemed to be stored in his body increasing his physical strength.

An hour passed to absorb the hole when it finally disappeared. On top of the mountain, Ryurai and Byakko appear in front of Itsuki. 

They wore the same clothes but now part of the skeleton mask covered part of their face. While the Byakko covers her right side from her forehead to her cheeks, past her eyes, Ryurai has a similar one on the left.

"Looks like your theory worked, Itsuki"

Itsuki only nodded as he felt the power in his body. He doesn't seem to be a hollow or a Shinigami, he's in the middle. The two zanpakutos only looked at him as he felt the changes in his body.

 Knowledge of some techniques flashed through his mind; it was instinctive.

Opening his eyes, he felt as if he was releasing his outer layer. Well, he took off his outer layer, as his hollow shell began to shatter. 

All that was left was Itsuki who stood in the middle of the barren land with a trace behind him, a trace of a body. Bodies littered the place behind him as he looked back.

Thinking of leaving this area, he stepped forward only to find out that he had surpassed it. A little Sonido is used with that step. Looking at his body, he felt the need to familiarize himself with his new strength. So, he committed another massacre but only used his physical abilities.

 After getting used to his strength, he started experimenting on himself. The outer layer of his skin had hardened, and his regenerative abilities increased, taking only a few seconds for the wound to heal.

He managed to combine Shunpo and Sonido together, creating an advanced Shunpo technique, sending his speed to a new level.

He felt that his senses had also increased in addition to being able to find reiatsu more easily.

Raising his hand, he pointed his finger at the bne hole in the distance.

Tve hollow was finishing his own business when a streak of blue pink light obliterated his existence.

Looking at the smoke coming out of his finger, Itsuki made sure that he most likely had all the basic abilities of arrancar. The move he just used was cero. He could increase his strength by deciding how much reiatsu he put into motion.

Itsuki suddenly heard a dragging sound on his right. He was so engrossed in forming the cero that he forgot to pay attention to his surroundings. A midget there trembled as he tried to hide by rolling into a ball and putting his hand over his head. 

The boy had short green hair and a broken hollow mask on his head. The hollow mask had a crack to the left of its mask while its four teeth were missing. He had a long scar that reached his nose and a red line on his face. She was wearing a green dress with a hood that covered her entire body.

Opening her brown eyes, she looked around and saw no one. It seems like the bad guy is gone. Suddenly he felt something behind him and jumped forward. 

Looking at the figure, he was first fascinated by her face but then remembered that it was the bad guy who shot out that terrifying beam. Sweat flooded his face while tears threatened to come out.

"YESYOOOO!!!!!"

A loud cry came out from his mouth as his tears gushed out like a waterfall. You can see his long canine teeth from his lower jaw. Itsuki was stunned and did not know what to do. 

He was currently in front of Nelliel Tu Odelschwank, a former espada and an arrancar who had lost his ability. Restored to the form of children, he also returned to that mentality.

Itsuki has no experience with children so he is stuck there, unable to do anything. 

Taking it, she simply hugged him in front of her like a ball as she cried. His feet hung in the air as his cries slowed.

He actually saw the man before his eyes. She's too pretty. Seeing the difficulty in her eyes as she hugged him, she began to feel sorry for him. Maybe I should play timeless tag with him?

Itsuki saw that he had stopped crying as he heaved a sigh of relief.

Nel looked at the clothes the man was wearing and started shaking once more.

Waving her hands and feet, she shouted while pointing at him

"Yy-you, who are you?!"

"Minamoto Itsuki, a Shinigami."

'S-Shinigami... That means he's a bad guy!!!!'

At first, he panicked and squirmed but realized that he did not let her go so easily. Suddenly a thought flashed across his head as a sly smile appeared on his face,

"Shinigami-san, want to play timeless tag?"

Seeing that he was not squirming anymore, he lowered him down. As soon as his foot touched the ground, he immediately tagged Itsuki and ran, running,

"Tag you that"

Itsuki just saw him escape.

'Children are a handful'

Suddenly sensing something, he disappeared towards where Nel had just left.

Nel slowly ran with his short legs while looking back. Seeing that the bad guy wasn't chasing after her, and his plan seemed to work, he stopped with a sigh, sighing,

"Sweets dat I'm too fast for the bad guys"

A satisfied smile was plastered on his face as he imagined himself beating Itsuki.

Observing his surroundings, he became confused, he became confused,

'Where am I? Where…?'

Suddenly, a shadow engulfed him as a huge hole appeared. A scream came out from his mouth while sweeping his claws at Nel. Nel was too shocked to move as the claw got bigger in his eyes. 

A mysterious light appeared in the eyes of his mask when another figure appeared blocking the attack. Itsuki quickly sent an attacking hollow.

Turning to Nel again, she saw that once again tears were threatening to come out of her eyes.

"W-Did you just save me?"

Itsuki never answered as he examined the wounds on his body. At first, he thought it would be nice to meet Nel's son, but reality hit him harder than a truck. He just decided to ignore her because he knew she was not alone.

Seeing Itsuki leave, he suddenly shouted,

"W-did you run away?"

Itsuki never looked back, though,

"A-is it just going to run away?"

Seeing no answer, she started crying,

"Meanie, I want to play again! I want to die and stop now"

A check mark appeared on Itsuki as she felt annoyed for the first time in history. Seeing that he did not leave, Itsuki turned around and gestured for him to follow. Nel was instantly delighted when he saw this and ran to Itsuki, hugging her all of a sudden.

Itsuki froze with a sudden hug while Nel was babbling. Taking it, Itsuki looked into his eyes,

"Guards, where?"

"I don't know, I lost them"

Itsuki didn't know what to say. He knew that both of his 'brothers' were unreliable, but he never expected them to be this unreliable.

"Shinigami-san, want to continue playing timeless tags?"

Itsuki was about to shake his head when Nel had already escaped. Tired of being led by this child's wishes, he simply grabbed it and placed it on his shoulders.

"D-dis isn't how eternal tags work...!"

Itsuki chose to ignore him and continued to look for his elder brother so that he could hand it over to them, and he could leave this place. While walking, he discovered that his eye abilities had improved. Activating it, he would see lines floating here and there.

 To experiment on various things, he put Nel to bed and went some distance away. He traced the line with the sword only for a huge gap to open and suck it all up.

Creating distance, the gap began to close similar to someone healing a wound. It seemed like he could, on some basis cut through the concept of space. He had not been able to kill her because he did not know how, and he felt his eyes were not strong enough.

 Returning to Nel, they continued their journey when she woke up. Itsuki had no idea how long he had been in Hueco Mundo, due to being in that vacuum and the fact that there was no concept of day and night inside Hueco Mundo. The sky remained the same wherever Itsuki went.

Right now, Itsuki had just walked in a tattered Shinigami outfit and the captain's haori when he heard some sounds.

"NELL...!!!!"

"NEL, DON'T KNOW!!!"

"BRING! BRING IT!"

A group of strange people looked around while shouting for Nel, unaware of the possible danger it could cause.

One was a humanoid Arrancar whose head was almost entirely covered in a mask, which resembled an insect-like head with large jaws and horns.

 His left eye is yellow and can be seen through the eye hole while his right eye is covered by a purple cloth. Blonde hair was seen falling onto his back while the top of his purple body was covered by a vest-like white armor. 

Below him was a hollow hole located near his stomach and he was wearing a light purple waist cloth. He has three fingers on each foot.

The other is a rather large man. He has a large body with small limbs. He was wearing a hooded yellow body suit with black spots of various sizes. His head was huge, almost as big as his body. 

Unlike other arrancars, his sinewy tiki mask covered his entire face where his eyes and mouth functioned as if they were his. The mask had exaggerated colorful features including large eyes, teeth, and a protruding nose.

The last is not arrancar but a snake like a hollow. His mask was a simple plate on his head with horns on both sides. He has big pink lips and teeth. Its body consists of a hard and sturdy back with a lighter colored bottom.

"Pesches! Dondochakka! Bring it!"

Nel started running towards them when he noticed Itsuki's absence.

"Ofis..."

Itsuki looks back at Nel as Garganta opens next to him. Itsuki gave a small smile as she looked at the unwillingness in her eyes while a hint of water appeared on the edges. He is quite attached to Itsuki throughout their journey and does not think that they will part when he reunites with his brother.

Seeing this Itsuki took out a feather and gave it to her, it was from Seikyo. Itsuki had found it in one of his pockets, it must have fallen a while before his empty transformation.

Itsuki did not speak as he patted his head and walked over to Garganta. The three friends had just seen Nel and rushed towards her.

The brave face replaced her sad face as she wiped her tears and grasped her fur.
