'Summon/Kyuubi thoughts'

It was the 10th of October in the Hidden Leaf Village. Minato was just finishing up the last of the paperwork in the Hokage's office. Then, as the pen just began to stroke the paper to finish the final signature, the Kyuubi no Kitsune attacked. At first, all everyone felt was a huge wave of KI flow over the village. Minato had the ANBU and Jonin prepare for an invasion on the Leaf. They didn't realise it was a sharingan possessed fox.

A few hours into the attack, Minato had ran to where his wife, Kushina, and new born son were. His battle with the masked man had delayed him enough. As he ran he began the hand seals for the 8 trigrams sealing technique. When he arrived, his wife erected a barrier of chains around the 9 tailed beast. Eventually, the fox was forced into the child. Kushina died from exhaustion from using her chakra intensive chains so soon after childbirth. Minato's last thoughts were 'Oh no!' as he saw the mistake in his seal as the Shinigami pulled his soul into its belly.

13 years later, Naruto stood before Mizuki, claiming that if he tried to hurt Iruka again, "I'll KILL YOU". His eyes had become a dangerous red with canine slits for a pupil. Red chakra coated him as he made the infamous seal and created 1000 Kage Bunshin. Each had a chakra cloak covering them. Mizuki died that day, as did Iruka's current opinion of Naruto. 'He's not the boy I cared for.' He thought as Iruka stared at Mizuki's remaining blood splatter. 'He's a shinobi.' So in respect, Iruka took off his headband and threw it to Naruto. He caught it in one hand without even looking Iruka's way. Then, Naruto collapsed.

Drip, drip, drip. The water dropped calmly as Naruto landed with a softened splash. The Kyuubi looked down at the kit. 'So weak.' He thought. Then, it hit him. He didn't need to escape the boy. Just take over the brat. He put his plan into motion. He extended a bit of chakra to the boy to wake him in his mindset.

Naruto woke in the sewer with a start. He got up and brushed himself down and looked around. All he saw one way was an endless road, and the other a huge cage. He approached said cage and peered inside. He was met with big eyes as the figure of a giant fox with nine huge tails appeared before him. Naruto started to get scared. Before him was the reason he was hated. He couldn't keep up his mask of happiness. He broke down in fear. This was the opposite of how he wanted to end today. Then the fox vanished. In its place was a man around 20 years old. He was well dressed. He had 9, fox like, tails on his back from where his tail bone should have ended. He approached Naruto and hugged the boy. "All your pain. It's hard to live such a horrible life. So how about you live here? This is your mind, anything you want to appear here appears and if you want a change of scenery, well, that too is well within your power."

Naruto looked up at the Kyuubi. He knew the man before him was a demon. So why did he not feel scared? It was like a brother he should have had long ago had found him. He looked up at the Kyuubi. "No." Naruto stated, the Kyuubi's embrace tightened a little, but Naruto carried on speaking. "But if you want, you can help me live my life in the real world!"

The Kyuubi was having a hard time processing this. The brat was practically offering him ½ of his end goal. This shouldn't have been happening for at least another 6 months. Needless to say the Kyuuni gleefully said "As you wish, little brother." It was fortunate Naruto couldn't see his face, or else the jig would be up from just the wicked smile that was plastered across the Kyuubi's face.
