1 year have passed since Tsunade was training Gouken during this year he mastered his dragon fire, Earth Wall, and Lightning Wolf jutsus to perfection and doesn't even need handsigns.
Tsunade decided to teach him the art of medicinal ninjustu 3 months into his training. He mastered everything including the Creation Rebirth but didn't learn the Strength of a Hundred seal.
Gouken: "I must say it hurts me to see you go."
Tsunade: "You know we will probably see each other during the war."
Gouken: "If I don't die in the front lines Bahahaha."
Tsunade pulled him into her embrace and as a 6 year old he was significantly shorter than her causing his face to go right between her mountains.
Tsunade: "Don't talk like that."
Gouken: "You know it's a possibility."
Tsunade: "Promise, Promise me you won't die in the war."
Gouken: "That is a hard promise indeed but one I can't accept."
Their relationship has got close during this last 1 not necessarily lovers but very close friends.
Tsunade: "I said promise me." She started crushing his back.
Gouken: "Okay okay I promise."
After seeing her off he goes back to the forest to train.
Gouken: "I have finally mastered it." Gouken had a massive smile on his face.
Gouken turned his body and put one foot forward pulling both his hands back. Lightning started to spark around him and a ball of blue fire slowly formed in his hands. Cocking his arm back one more times he yells and throws his hands forward.
Gouken: "HADOKEN!"
A ball of fire the size of a car came out of his hands. The ball of fire hand lighting around it and was increasing speed. It destroyed 7 trees before hitting a boulder and exploding destroying it.
Everything in its path still had small sparks of lightning and burnt marks on it.
Gouken: "This can be stron...." Gouken jumped back feeling killing intent from the bushes.
A sand ninja throws two kunai and runs towards him.
Gouken dodges the kunai and runs towards the man. The man grabs his sword a stabs at Gouken seeing this Gouken sidesteps and punches the man in his gut.
The punch was strong and made the made drop his sword then the two go into hand to hand combat. Gouken ducks under a kick then sees the man punching towards him and headbutts his hand breaking every one in his fingers and his knuckles.
Man: "Arggghhh."
Gouken: "Tatsumaki Senpukyaku!"
Gouken jumps in the air and spins rapidly with his leg out kicking the man's head 6 times before he falls back down.
Man: "Earth release- Earth Dragon."
Gouken didn't see the attack coming and didn't have time to talk. In a last ditch effort he slammed his hands on the ground.
Gouken: "Earth style-Earth wall."
The wall came from the ground and the earth ground smashed into it. Gouken left out a breathe of relief but then the wall started to crack and the Dragon crashed through it.
Gouken: "Dammit!"
Gouken put more chakra into the ground and yelled. Another wall came out of the ground but this one was a silverish color and shining.
The earth dragon smashed into the wall shattering instantly. Gouken looked and saw the ninja knocked out.
Gouken: "What the hell is this." Gouken goes up to the wall and examines it.
Gouken: "Platinum. This is Platinum if I remember correctly it's extremely strong."
Gouken: "Is this what they call a Kekkei Gekkai I guess I will call it Platinum Release."
The sand shinobi falls down and Gouken picks him up dragging him to the Hokage's Office. Gouken busts through the doors leaving the Hokage suprised.
Hiruzen: "You can't keep coming in here whenever you fell like it."
Gouken: "I thought I would let you know that I was attacked by a sand shinobi."
Hiruzen: "What!"
Gouken: "Here."
Gouken throws the body on the ground and the hokage punches the desk.
Hiruzen: "This bastard was a spy. He was a flower shop keeper."
Gouken: " I was training in the forest and just finished my new jutsu when I felt killing intent and saw him.
Hiruzen: "It looks like the sand doesn't put me in their eyes."
Gouken: "It seems they now I am the jinchuriki too."
Hiruzen: "I guess I need to speak with the hidden sand."
Gouken: "I will let you take care of it."
The next day Gouken went to the forest he started training his Platinum release.
Gouken: "Platinum release- unbreakable wall."
Gouken preforms some hand signs and smacks hand on the ground. A silverish wall the size of a door came from the ground.
Gouken: "The platinum release is really taxing on chakra and I need hand signs looks like I have a lot of work to do."
