Naruto: We are invincible

Izuna asked in confusion:

"Where am I?"

He remembered that he was about to die, or rather, he knew that he was going to die.

He knew that once he fell asleep he would never wake up again, yet here he was, lying awake.

He could hear people talking around him! And the voices were quite loud.

"Oops," Izuna exclaimed when she heard a familiar voice.

He also heard another familiar voice, but this body felt strange, like all of his senses were different than he remembered, but in a good way.

He no longer feels the constant pain from the multiple broken bones he had in his past life.

"Who's that?" This time it was a woman's voice he didn't recognize.

Izuna felt that she had observed long enough, so she decided to open her eyes.

He tried to sit up, but accidentally groaned in pain.

He opened his eyes, but the bright light in the room made him squint.

His eyes felt stinging, as if they had never seen light before. He instinctively activated his Sharingan.

Izuna looked around, and the first thing that caught his eye was a group of people, all looking at him curiously.

He quickly scanned each face, they were all strangers to him, until his eyes locked on a young man with white hair and red eyes.

"Damn it," Tobirama cursed under his breath, a look of disgust on his face.

"Tobirama!" Izuna shouted, startling everyone, and then sat up suddenly.

His right hand instinctively formed a tiger seal.

"Fire Style - Great Fireball Technique!" He roared as he prepared to attack. But Naruto rushed in front of him first.

Naruto grabbed Izuna by the neck and threw him to the ground.

"Traitor!" Izuna roared, and he saw the burning Sharingan in Naruto's eyes.

"Let me go, or you will die with him!"

However, Naruto ignored his threat and released a stream of Lightning Chakra, interrupting Izuna's chakra flow.

"...Brother?" Izuna whispered in disbelief, then fainted.

The last image he had before he passed out was of a man with a Sharingan very similar to his brother's.

"What are you doing?" Tobirama asked Naruto sharply. "Have you ever thought about the consequences of resurrecting an Uchiha like this?"

"He attacked you because he saw you," Naruto retorted as he picked up Izuna and tied his hands and feet.

"I guess there's a feud between you two," Naruto said.

"Yes, he is Madara's brother," Tobirama explained. "I killed him," he said calmly, but there was a hint of sadness in his tone. Everyone gasped.

"I agree with Tobirama, Naruto-kun, reviving a Kage-level ninja without any preparation is far too... reckless," Hinata said.

Naruto shrugged and continued to tie up Izuna.

"Why did you bring him back?" asked Hashirama.

"To solve the mystery," Naruto replied. "I want to know what happened to his eyes and how they became the Rinnegan."

"It was Madara who stole his eyes..." Nao said.

"That's a lie!" Izunai suddenly woke up and said loudly.

Everyone looked at him who was tied to the ground.

“That’s a lie. I was dying, so I voluntarily gave my eyes to my brother. He is my brother, and we will never hurt each other!”

"Well, it looks like that problem is solved," Itachi said thoughtfully.

"Are you telling the truth?" Naruto asked, and Izuna nodded firmly.

"Interesting," Naruto said, stroking his chin. "Why did you give him the eyes?" Naruto asked.

"Why should I tell you?" Izunai asked with a smile. "I am a prisoner now, and you don't even give me food," he teased.

Naruto looked unhappy.

"How about this, you answer a question for me first, and then I'll answer yours," Izuna said with a smile.

"Alright," Naruto sighed helplessly.

"Who are you?" Izuna asked Naruto.

What is the relationship between this blond kid and his brother? Apart from the blond hair and the whisker-like marks on his face, they really look alike.

"Senju Naruto," Naruto replied and Izuna narrowed her eyes.

"You obviously have the same Sharingan as me, why is your last name Senju?" he asked.

"My father is an Uchiha and my mother is a Senju, so I had to choose just one last name," Naruto said with a shrug.

"You're lying," Izuna said sharply. "The Uchiha and Senju clans are sworn enemies, and it is absolutely impossible for members of both families to meet...especially in times of war," he emphasized.

"I told you so," Tobirama said. "Resurrecting someone who has been dead for years is not a good idea."

"Dying?" Izunai muttered to himself. "I remember I was dying, but why am I here?" he asked in confusion.

"I was the one who resurrected you," Naruto confessed.

"No one can bring the dead back to life," Izuna retorted.

"The ninja world has changed drastically, you've been dead for a long time...uncle," Naruto said. Izuna's eyes widened in shock.

"This is impossible, Madara is still alive. Are you saying that you are his grandson? Prove it to me!" Izuna shouted.

Izuna narrowed her eyes and noticed that Naruto's Sharingan had turned into a Mangekyō Sharingan.

"Another one," he thought in amazement.

The space in front of him began to distort, and Madara's military fan flew out from Naruto's alternate dimension.

"Well, it seems to be true," Izuna sighed.

He looked up and saw another blond man in the room.

Naruto followed Izuna's gaze and said with a smile:

"This is Madara's son, my father." He pulled Minato in front of him.

"Uh…nice to meet you…uncle," Minato said awkwardly.

"You mean, you are my brother's son?" Izuna asked in disbelief.

Minato nodded. "I can't tell," Izuna said, and Minato lowered his head in embarrassment.

"It's all because of your father's hair color," Kushina said, patting Minato's shoulder.

"Tell me," Izuna said. "How much time has passed? It's so strange to see so many Senju and Uchiha clansmen sitting together peacefully."

"Times have changed, Izuna," Hashirama said. Izuna glared at him fiercely. "The ninja world is no longer the battlefield we were familiar with. It is no longer based on families, but on villages. Madara and I joined forces to establish the first ninja village."
