Hello, so this fanfic is about Naruto's older brother. This a alternative fanfiction of my idea, basically this is fanfic, how the things could've turned out.

So please Enjoy.

On the small hill, there was a boy lying there, he looked tired, but peaceful, as he breathed the refreshing breeze. The boy was thinking about his old friend, Itachi. They always seem so playful when their parents were around them, but in reality, they were friendly rivals. Even though Uchiha was the older one, and he was much more stronger, especially with the sharingan, but the other one never seem to give up on the thought that he could beat him in a sparing match.

Someone was going up the hill.

"Hello there," Smiled friendly the man.

"Can I help you, mister?" Asked the boy.

"In some sort of way, yes" He chuckled as he said that. "You're Koske, right?"

"Yes… That's my name." The boy looked at him suspiciously.

"Well then, my name is Izuga." He flashed that smile again. Koske always found something irritating about optimistic people, well maybe he just never understood them. " Your father supposed to talk with you. It seems you have no idea what's happening, do you?" The smile faded away from the mans face.

"Koske, come here, we need to have a serious talk." The boy heard his father voice and came up right to him. "Listen, this is very serious, so listen very carefully." Koske nodded. " And don't tell your mother anything yet" The fourth coughed and finally began. "That man, you just met, chose you to become a Jinchuriki of a 10-tailed beast." Minatosaid that with a hint of sadness in his voice. Koske chose to be as naïve as possible. He knew all of this, the jinchurikis, the beasts, and no one would even think that this kid is that smart.

Koske asked some naïve questions. After that, he just couldn't puzzled up the pieces together, so Koske decided to ask his father.

"But… Why me? Isn't it a better idea to seal it up in a strong shinobi?" The boy asked looking confused. The hokagelooked lost.

"Well that man, believes in you." Minato looked like he was struggling to say those words.

"I'm just a weak kid, It's a miracle I'm still walking on my own feet…" He whispered that, so his father wouldn't hear that. But then he looked scared for his life. "Mom?" Mumbled Koske with a nervous smile.

"Kushina?" Fourth jumped backward. "Good to see you…"

"What the hell do you think you're doing?" Angrily said the red-haired woman. "Did you fell on your head or something?"

"Kushina, let me explain myself." He looked at his son. "Kokse go home, we will be back quickly"

Without any word, the boy went home. He sat down on the stairs, high enough, so they wouldn't see him. To be honest, he was confused. But then he came up with an idea. Maybe they want to seal the 10-tail in him, so they would have more time to find a really strong shinobi, cause this is the most logical explanation. He is sick, he is dying slowly. Day by day, his life is becoming shorter and shorter. There is only 5% chance that he would live to his adulthood. And this thought scared Kushina so much. Koske wasn't even shocked by this, he felt like some sort of problem to his parents, and it hurt. His little heart clenched in pain as he stressed himself with that thought. Koske grabbed his chest, breathing deeply, so that the pain would go away. But in 5 minutes he lied on the stairs still in pain.

"Shit…" He whispered. "How I managed to stress myself this much?" It took about 10 minutes, and the pain little by little began to fade. God… It could've been the end for me… It would be so nice, to find your own kid lying on the stairs dead, Koske thought to himself. Suddenly the door opened with a loud thud. Kushina was furious.

"Kushina please, you didn't have to hit him!" Minato ran after his wife.

"DO YOU EVEN HAVE A HEARTH?" Koske didn't think, that Kushina would be so upset about this.

"But it's completely safe, you shoul…" Minato couldn't even finish the sentence as Kushina broke the table in one swing.

"YOU ARE SEALING A 10-TAILED INSIDE YOUR OWN SON!"

"WHAT'S THE POINT, HE IS DYING ANYWAY!" The hokage screamed on response.

"Oh.." Koske muttered. I think nobody would expect Minato to scream. It's like impossible, and there's the scene of screaming Minato was just in front of him. Well he heard those words from his father. Ouch, that hurt, Koske thought to himself while his chest clenched in pain. "Calm down, we know that already… And beside, dad is in stressful situation…" Koske mumbled, but he knew, that those words were the truth. Minato wouldn't say such a thing without any reason, this was the sad truth, everybody knew. The boy, slowly but surely, climbed down the stairs and sat down, so they could see him. Kushina was standing with a mouth open wide, as the tears were pouring down her face, she wasn't ready for such harsh words from her husband.

"He actually has a point here." Koske said that casually.

"You… You heard…" Kushina was looking really upset.

"Yes, the whole conversation. Well I have few years, and in the meantime, I'll become a Jinchuriki. So that you have a little time to find someone strong." He looked at Minato, who looked really confused.

"How did you even know that?"

"I managed to figure it out."

"And you are not scared of the 10-tails?" Kushina asked very carefully.

"Why would I? I'm not scared of death, so why would I be scared of that?"

"Koske is that you? I never seen you so serious…" Minato scratched the back of his head.

"Well we are talking about serious stuff. About the 10-tails after all and…" He stopped for a few seconds and then continued " Can we say world peace? Cause a 10-tail roaming around isn't considered peaceful." He got up and looked at his father. "And if I die in the process?"

"There's no way you would, there's some good medication, you'll take so the pain wouldn't be that serious."

"Good to know." He muttered, not actually believing his father. "So that's setteled, I'm becoming a jinchuriki."

"But.." Kushina tried to say something, but Koske just looked at her, so she would calm down.

"Let's be honest, I'm dying. And there's no chance for me to survive." He said that, with no regrets.

"Koske don't say that!" Kushina got up.

"Why you don't want to face the reality?" He looked at her frowning. "Dad already did." Koske grinned at his father. Minato was kind of lost, he didn't actually meant that. Suddenly, some one knocked on the door. Minato opened the door, there was his old team. Nohara Rin, Uchiha Obito, and Hatake Kakashi, they all looked happy… Well except Kakashi, you really can't tell if he has any emotions at all.

Kushina looked at Koske who was, as she called "grumpy state". He lost interest in what's going on.

"Come in!" Minato looked very happy as he let them all in. He hated, he pitied his father, he acted so happy so around them. Even though all of them are almost grown ups, he acts like they are his children. Minato is so kind, giving each of them attention, but he never gave this much attention to his own son. Koske turned around and was about to leave this place and get back to his room, but suddenly Obito came running to him with a big goofy grin on his face.

"How ya doin' pal?" He smiled as he looked at The boy.

"Eh.. Nothing much… You should buy some flowers though." He muttered as he noticed Uchiha's confused face. "My funeral is going to be soon, so brace yourself… Pal." Koske ended his phrase with sarcasm, as he got up the stairs and locked the door behind him

"Wh-h… what?" Rin looked at Kushina. Woman hid her face, while tears began pouring again. "Lady Kushina! Are you alright?" Girl ran up to her and hugged her.

"Yes… It's just…" Kushina tried to say something but her voice was cracking as she spoke.

"Kushna, it's alright. I'll tell them." Minato sat down on the sofa and sighed.

Koske was angry once again at his father. He leaned against his door, as he slid down it. He couldn't bare such a pain. The boy felt how tears were pouring down his face. He curled up and clenched his teeth in pain. Minato was talking about the boys disease. And in about a minute, Obito was running up to Koske's room. Uchiha knocked on the door carefully.

"Hey… Koske… Could, open the door?" He asked really quiet. The boy got up, and unlocked the door. He was still clenching his teeth.

"What.. Do you want?" Boy hissed at Obito, as he opened the door.

"Look, I'm really sorry, for being so rude. And I'm overall sorry, for your disease." Uchiha said that, looking at the boy.

"Would your sorry change something? If you would be there for me, something would change?" Koske stared coldly at him. Obito noticed the tears on his cheeks.

"Were you crying?"

"If you would feel this terrible pain… You'll understand me." Koske wiped the tears from his face.

"Is it that bad?" Obito looked at him anxiously. Koske just sighed and was about to close the door. "Wait! Minato-sensei, asked you to come downstairs." The boy immediately passed the Uchiha and was going down the stairs.

"Koske, take your medicine." Kushina muttered as she was cooking. The boy flinched at her, and came to a basket. He drank up two pills.

"Is that all?" He hissed

"You should sit with us today." Minato patted on his back.

"And if I don't?"

"You don't have a choice." Grunted Kushina.

"Great." Koske grabbed some book from the shelf and sat down at the table. Rin looked at the cover, and gasped.

"Are you reading about the clans?" Rin ran up to him.

"Yes…" He looked suspiciously at her.

"Wow… And you are only seven years old." Rin was looking at the boy with big sparkly eyes. He shrugged and continued on reading.

"I forgot to tell you… Tommorow, you are going with me to that man again." Minato sat down beside him.

"We gonna seal it tomorrow?" Koske grunted with his nose in the book. Obito was standing behind them and listening.

"Yes…" Minato got a punch in the stomach from Kushina. She looked with an angry expression at him.

"What are you gonna seal?" Kakashi asked curiously.

"It's nothing." Murmered Namikaze looking at Koske.
