I am making it so obito and rin are 4 years older than kakashi and guy is in the academy earlier.Kakashi will graduate and be placed under Minato with obito and rin who are nine.
———————————————————————
Gouken was walking into the academy for the first time and he was less than impressed with some of the people in front of him.
There were a few people that he saw as interesting those people were: Kurenai, might guy, kakashi, and Asuma.
Teacher: "This is our new student. Go ahead and introduce yourself."
The class looked at him with curious eyes none of them have seen someone dress so oddly.
Gouken: "My name is Gouken it's nice to meet all of you but don't try to fight me Bahahahaha."
Everyone looked at him like he was crazy even kakashi raised his eyebrows.
Teacher: "Okay go choose an empty seat."
Gouken walked up and sat at the back of the classroom behind kakashi and guy.
-6 hours later-
Teacher: "It's time for sparring everyone head to the training field."
Students: "Yes!"
(Training grounds)
Teacher: "Okay first will be Kurenai vs Gouken."
The two step forward kurenai was cheered by some of the boys while everyone else looked at Gouken to see what he could do.
Gouken: "My name is Gouken thank you for fighting with me." Gouken puts his fists and palm together and bows.
Kurenai: "I'm Kurenai likewise." She didn't want to be rude so she slightly bowed too.
Asuma: "Kick his butt Kurenai."
Guy: "This guy looks strong I want to fight him as well."
Teacher: "Begin."
Kurenai rushes towards Gouken and sends a fist. Gouken moves his head to the side and grabs her arm swinging her.
Gouken: "Bahahahaha."
Gouken throws her across the circle platform. She gets up and rushes him again but this time Gouken runs towards her too.
The two collide fists then kurenai kicks at his stomach. Gouken sees it coming and kicks her in the stomach sending her back before she could connect.
The teacher was suprised at his combat skills then called the match.
Teacher: "Gouken wins."
Asuma: "I should beat him down."
Guy: "That's the power of Youth. Kakashi my rival we might have some competition."
Kakashi didn't say anything and just looked at Gouken.
After that the rest of the student fought and the school day ended. Gouken walked home and began to meditate.
Gouken: "I need to start training my chakra war will start soon I need to be ready."
Gouken decided to walk to the hokages office for some chakra paper. When he got there a guard was outside the door and didn't let him in.
Guard: "The Hokage is seeing an important guest you cannot enter."
Gouken: "OLD BASTARD LET ME IN I NEED SOMETHING!" The guard feel to his knees while holding his ears.
Guard: 'How can such a young kid be so long.'
Gouken's yell caused the guards eardrums to burst and a little blood cane from his ear. Seeing the guard down Gouken opened the door and walked inside the office.
The hokage has a annoyed expression on his face but Gouken didn't pay attention to that instead he looked at the blonde haired girl that was standing in front of him.
Tsunade: "Go anyway brat can't you see we were discussing something."
Tsunade was rubbing her ears as they hurt from his yell. She got annoyed and punched him in the gut.
Gouken: "Bahahahaha although shy women are good I have always liked feisty." Gouken laughed while wiping blood from his mouth.
Tsunade: "Brat what do you know about women."
Gouken: "Enough to know that yours are a lot large than average Bahahahaha."
Hiruzen chuckled while tsunade got even angrier as he reminded her of a certain pervert.
Tsunade: "It seems you want to get pummeled."
Hiruzen: "Enough Tsunade. Gouken what did you need so urgently."
Gouken: "Chakra paper I want to test my chakra affinity."
Tsunade: "Here brat now leave." Tsunade handed him a piece of paper from here pocket.
Gouken decided not to leave so the hokage could give him some scrolls. He put chakra into the paper and watched as the paper wrinkled then turned to dirt and crumbled before igniting and burning to ash.
Gouken: "So lighting, fire, and earth not to bad I could work with this."
Tsunade: "What the hell Sensei who is this boy."
Hiruzen: "Tsunade don't tell anyone this but that boy is that jinchuriki of the four tails."
Tsunade: "What!" Her eyes darted back to the boy with surprise then pity.
Tsunade knew how people of this world viewed jinchuriki. She was suprised at how this boy was so calm even though he knew there was a monster inside him.
Gouken: "That's Son Goku."
Hiruzen: "What."
Gouken: "His name is Son Goku calling him four tails is an insult to him."
Hiruzen: "How do you know that."
Gouken: "We are now brothers I have talked to him and we will share my body."
Hiruzen: "He listened to you."
Gouken: "Yes not as a slave or monster but as a friend."
Tsunade: "But he is a tailed beast."
Gouken: "So he is not a mindless killer. Son Goku is just like your summons just stronger."
Gouken: "With us working together it will increase my power greatly and I can defend our home."
Tsunade looked at the boy and smiled.
Gouken: "Hokage can I borrow some scrolls that are my affinities."
Hokage: "You know I am not supposed to just give those out."
Gouken: "I know there is a war on its way with your help I could help defend the village."
Hiruzen: "You think that you can help us win if there is a war."
Gouken: "I don't think. I guarantee it."
Tsunade and Hiruzen looked at the boys confidence and couldn't help but smile.
