He gasped when he drew his sword out of the dead body of the man who made his life into a living hell. He rose into a standing position and looked at the grey ceiling of the underground room he was in. All around him were corpses of Shinobi. His eyes returned to blue, and his six whiskers vanished from his cheeks. His normally blond, spiky hair was stained with red blood. His clothes were mostly shredded. Only the Katana in his right hand and his black pants remained. His body was full of injuries, but nothing his enhanced healing factor couldn't handle.

'Finally… after 10 years… I killed this bastard,' thought the young man. He roared, and his voice echoed through the dark corridors of the underground hideout of the organization he belonged to for ten entire years.

He turned around but stopped when he saw the wall behind the throne where the bastard normally sat he just killed. He never noticed, but something was off about the wall behind the throne of the corpse at his feet. He stepped over the corpse and raised his Katana. He inhaled a lot of air, and out of nowhere, multiple lines in the air appeared before him.

The wall crumbled to dust from all the sword strikes the man unleashed in a single moment. He stepped through the revealed passage and didn't need to walk to see a small light source. He gritted his teeth when he saw the room. He always wondered where this cursed room was.

The cursed room, where he was made into a weapon. The room where foreign chakra was put into his body with force. He wasn't the only orphan back then who was brought to this room. He didn't know the exact number, but he would think about 30 kids were brought to this cursed room.

He looked around and remembered most of the room, but he didn't see everything. He saw a door he hadn't noticed ten years ago. With Katana in his right hand, he walked to the door and slashed the door to pieces like the wall before. It brought him some satisfaction to destroy things this bastard owned, even when he killed the tyrant who made him into a weapon.

He walked through the doorway and stopped in his tracks when he saw something he never expected to see. 'I knew this piece of shit did some nasty things… but this?' thought the young man. He clenched his free hand into a fist and couldn't believe his eyes.

In some kind of tank full of liquid was a woman. The woman looked thirty years old and had long, beautiful red hair. Her entire body was entirely on display since she didn't wear any kind of clothes. Not that it bothered the young man. In his training as a Shinobi, he was trained in everything he needed to survive in the Shinobi world. The young man looked at the woman and found this face in documents and books. When he was researching a specific topic, he came across the name of this woman and the picture.

The name of the woman was Kushina Uzumaki, wife of Minato Namikaze, the fourth Hokage of Konohagakure. She vanished 12 years ago when the Kyūbi (Nine Tails) attacked the village out of nowhere. Beside the tank with Kushina inside was a monitoring machine with a few displays of the status of her vitals, such as pulse and so forth.

'Now it's clear how Danzo came to the chakra of the Kyūbi. He used the former Jinchūriki (Power of Human Sacrifice) to extract some of its remaining chakra inside of her body,' thought the young man. He saw a file and took it. He opened the file, and when he saw his own profile, his eyes flashed crimson. Six whisker marks appeared on his cheeks before they vanished again. His red eyes returned to blue before he saw his name.

His eyes widened when he read his full name. All this time… he never knew his last name. He was simply Naruto. He had no last name since he was a war orphan.

The young man read through the information he never knew about himself. He always wanted to know who he really was and what his hidden past hid from him.

When he finished reading, he clenched his file, and both hands burst into flames, letting the documents inside the files burn to ashes. The last remaining information that could be seen was the name of the young man.

Naruto Namikaze.

Naruto was always someone different. He couldn't use chakra like others from the very beginning, but somehow, he became a pseudo-Jinchūriki of the Kyūbi. He could use the chakra of the Kyūbi without a problem, but using normal chakra like everyone else was impossible for him. As it turned out, his chakra network was damaged, and when the experiment was done where the chakra of the Kyūbi was put into his body with force, something changed inside Naruto. His chakra network was repaired completely, but somehow, his body didn't contain any normal chakra anymore. He only got the chakra of the Kyūbi inside him, but also just in one spot. In the center of his stomach was the seal where the chakra of the Kyūbi was stored.

Naruto could release the chakra of the Kyūbi inside him to let it flow freely through his body, but when he stopped, every chakra of the Kyūbi either returned or vanished from his chakra network. So that meant Naruto wasn't a normal Shinobi either. The he killed a few minutes ago wanted to kill Naruto at first, even when he was the first child who accepted the chakra of the Kyūbi without dying, but in the end, he had no other choice but to let Naruto live. No other child survived the experiment.

Since he needed a way to fight without relying on chakra like other Shinobi and without revealing his status as pseudo-Jinchūriki of the Kyūbi, he trained differently to become stronger and to be able to a Shinobi to survive.

Naruto Namikaze was irregular in every sense. He became strong enough to stay alive in this cursed Shinobi world, even without the ability to use normal chakra. Since he hated to use the chakra of the Kyūbi, he only used it when he had no other choice. In all the time he was in this cursed organization from the bastard he killed, he only needed to use the chakra of the Kyūbi 6 times in total. Besides those six times, he used other methods to fight as a Shinobi.

He developed everything himself without the help of someone else. It was either learning by doing, becoming stronger, or dying. He did everything to survive so that he could kill the bastard one day who made him into a weapon.

Naruto looked at the woman before him—the woman who married his father. Kushina Uzumaki wasn't Naruto's mother, even when Minato was indeed his biological father. Naruto was a pure Namikaze, meaning his mother was also from the Namikaze clan. He had no connection to the woman in the tank before him.

When Naruto understood it correctly, then Minato and his biological mother never had a real relationship. The information in his secret file let him come to the conclusion that both had one or more times of sex but never something serious. Naruto didn't even know if Minato Namikaze knew that he made his mother pregnant. His mother was from a little village in the land of fire. Both met when Minato was on a mission. At least, this was how it stood in Naruto's file, which he discovered and burned to ashes afterward.

Naruto didn't even know if he could Kushina Uzumaki. He didn't really have the desire to free this woman. The Hokage will discover that the secret organization Naruto had worked for in the last ten years was completely destroyed. When the Hokage would see this, he would also discover Kushina Uzumaki.

Naruto was about to turn around but stopped when he remembered one person who lived in the village. There was a girl in the village he often observed. It was because she was the true weapon of the village. He was just a cheap imitation since he didn't have the real Kyūbi inside him. Naruto only had the chakra of the Kyūbi but not the Kyūbi itself in his body.

The girl who was the true Jinchūriki of the Kyūbi was Kasumi Uzumaki. It wasn't much to figure out that the girl was the daughter of Kushina Uzumaki and Minato Namikaze. Kasumi Uzumaki was basically a younger version of Kushina Uzumaki with six permanent whisker marks on her cheeks.

Naruto only got his whisker marks when he used the chakra of the Kyūbi, but otherwise, he didn't have them. Now that he knew that Minato Namikaze was his biological father and Kushina Uzumaki, the wife of Minato Namikaze, making Kasumi Uzumaki their daughter… that meant he had a half-sister.

He should be happy to have discovered this fact… but he wasn't. One more thing that let his hatred for Danzo Shimura rise even more. He killed the bastard already, but even after he killed Danzo, the old bastard found ways to mock Naruto.

Naruto had a little sister all this time, and he didn't know it. He watched her multiple times, how the village treated her, and how much she suffered. He never cared about this since he went through far worse things than Kasumi Uzumaki.

He had to endure real torture from Danzo Shimura multiple times. It was everything to control the chakra of the Kyūbi Naruto got from Danzo. The torture was a method for Naruto to force him to use the chakra of the Kyūbi. Danzo wanted Naruto to be able to use the chakra of the Kyūbi without any form of problems.

Kasumi Uzumaki was alone, ignored, and had only three people who cared for her.

So what? Naruto had no one. He only had torture to endure isolation inside the organization since he was also a pseudo-Jinchūriki, and even inside the organization, Jinchūrikis weren't treated any differently. He had no friends or comrades. He always carried out missions alone. The things he had to endure were far worse than what Kasumi Uzumaki had to endure.

Maybe he was harsh, but Naruto didn't care. He was overwhelmed by his emotions. He looked at Kushina Uzumaki and gritted his teeth, raising his Katana. He made a series of slashes, turning the glass tank into little pieces. The liquid inside the glass tank streamed out of the destroyed tank and filled the room. Naruto caught the naked woman with his free arm and looked at her.

…

He threw his Katana to the side. The Katana bounced off the wall and landed on the ground. Naruto used both arms to carry Kushina Uzumaki, the lost mother of Kasumi Uzumaki, like a bride through the destroyed hideout. In every corridor he turned or the large room he entered, there were multiple corpses. Naruto killed every single member of the Root, a branch of Konohagakure's Anbu training subdivision. Naruto singlehandedly destroyed Danzo and his Root at just 14 years of age. Danzo made Naruto too strong without noticing it.

Danzo miscalculated how strong Naruto got in his training. Since he didn't become stronger like everyone else using chakra, Danzo didn't understand how strong Naruto really was, even without the Kyūbi chakra.

When Naruto came to his room, which he used for the past ten years, he laid Kushina Uzumaki on his bed. He began to fix her up and made sure she would stay alive. He knew that Kushina Uzumaki would die if he didn't do what he was about to do. He saw the seal on Kushina Uzumaki's stomach. It was almost the same as Naruto's seal. Naruto's eyes became crimson when he let the chakra of the Kyūbi run through his chakra network. His six whisker marks appeared again, his canines became longer, and his fingernails resembled claws.

He placed his hand over the seal of Kushina Uzumaki and began to push the chakra of the Kyūbi into the seal of Kushina Uzumaki. He felt how weak she became when he freed her from her prison. It was clear that Kushina Uzumaki was the former Jinchūriki from the Kyūbi.

Naruto had a blank expression on his face while he looked at the seal from Kushina Uzumaki. Red bubbly chakra came out of Naruto's hand and traveled into the seal on Kushina Uzumaki's stomach.

He didn't have to do this, but he did it anyway. He would give his half-sister her mother back. Even when he would vanish afterward and never return to this village… he would at least do one thing as a brother.

Naruto saw how Kushina's skin got color back, and her breathing stabilized. When he was done, he gasped once.

'Tze, she needed more chakra than I thought to stay alive,' thought Naruto. He walked out of the room and came back with some clothes for the woman. He would lay Kushina Uzumaki down on a spot where a normal patrol of Anbu would find her in the next 3 hours. But before he would do this, he needed to dress her. She was completely naked. Naruto wasn't embarrassed or had any hesitation to touch the body of a woman. He got special training against the seduction of Kunoichi. Many male Shinobi were dying because they fell for the seduction of skilled Kunoichi. Naruto became completely immune to this type of strategy. Touching a naked woman wasn't anything special for Naruto since he touched the naked woman on missions countless times.

A brothel was one of the best places to gather information. One of the legendary Sannin knew this and used those places to get information, too. Naruto was handsome for his young age and looked older than he was. It wasn't something he really had a desire to do, but women who worked in brothels were the best spies and informants.

Naruto didn't twitch when he dressed Kushina Uzumaki in the clothes. It had to be said that the top didn't fit since her chest was larger than the standard of Root's women's clothes. He had to press her breasts a little against her body to get the black top over her breasts. When Naruto was finished, he took Kushina Uzumaki in his arms again like a bride. He looked at her sleeping face and remained silent. His eyes became normal again since he wasn't using the chakra of the Kyūbi again.

…

'How could it turn out like this?' thought Naruto. He shook his head. There was no time since he was sure the Hokage would come and discover everything sooner or later. He wanted to be away from Konoha by the time everything was discovered.

Oh yeah, Naruto also dressed himself in new clothes. He was now fully equipped again and dressed like a Root member with a Katana on his back. His Anbu mask resembled a fox. He also wore the hooded cloak many Root Members were wearing on special occasions.

Naruto walked out of this cursed place and concentrated his breathing. He began to run, becoming faster with every step he took. His blue eyes were scanning his surroundings while he ran around the trees. It wasn't long before he came to the place he had in mind.

He placed Kushina Uzumaki against a tree and looked one last time at her sleeping face. 'Take good care of my half-sister,' thought Naruto. He turned around and crouched before jumping on a tree. When he landed on the branch, he pushed himself off the branch and vanished into thin air.
