The Kitsune Demon

Naruto and Hinata broke their embrace when they heard a cough from behind them. Separating they both blushed like they were caught with their hands in the cookie jar. Xua trotted into the room smiling when he saw their expression, " I'm glad both of you made it through whatever that was. I know it might be hard but you have to train both of your bodies have gone through changes and the sooner you train the easier it will be to get used to the changes. Both Hinata and Naruto understood the logic in Xua's words, with some effort Hinata and Naruto got to their feet. Before leaving they stretched limbering up after two days of sleep.

After that, they repeated there usual body training routine but instead of lagging behind like she always did Hinata was able to keep pace with Naruto. After their four Hours passed Yua and Xua took the fledgling shinobi back to the pool of spirit oil, Naruto and Hinata were hesitant to enter the pool after it caused them so much pain but after gathering their courage they sat in the pool of blue liquid.

Once they where seated Yua instructed them to pull the Nature Energy into their bodies so it was equal with their chakra. Naruto could feel the difference after his race change when he tried to absorb the Nature Energy present in the oil he could easily control the flow of powerful energy. When she was human Hinatas' control was extraordinary but as a royal kitsune, her skill went to an entirely different level. Soon both of them reached the state where their chakra had mixed with the Nature Energy creating senjutsu chakra.

Then a change started to happen on Naruto's and Hinata's body almost simultaneously, fox ears sprouted from their hair on their heads glowing a slight red, and their eyes also started to glow red. On their right cheek, a red crescent moon marking became stark against their white skin. The final change was Naruto's and Hinata's teeth and nail became sharp, creating a fearsome visage. The transition to sage mode only took Hinata and Naruto a second, but the amount of power it would bring them would only be found out through many battles.

Standing up Naruto felt power course through his veins, testing his strength he sent out a wave of chakra. The was a visible wave in the air originating from Naruto as it traveled through the air it caused the oil to ripple and sent his hair into the air from the wave. Standing beside him Hinata felt giddy when she felt the power at her beck and call, looking over at Naruto she felt her heart beat faster when she saw his powerful figure. Xua and Yua had a proud look on their face as they watched Naruto and Hinata, they both viewed the children as their own and would risk their lives to save their children.

Clearing her throat Yua interrupted Naruto and Hinata's self revelry, " The changes that your body as gone through are not permanent, but a sign that you have entered sage mode a state where your bodies chakra and Nature energy have fused creating senjutsu chakra. With this chakra, your old jutsu will be much stronger and new jutsu will become available with practice " Naruto and Hinata focused on Yua their training taking over. Moving away from the pool Naruto and Hinata faced each other preparing to spar just like so long ago.

Naruto and Hinata stared each other down while their chakra continued to build up, Hinata made the first move. She left a deep impression on the ground as she flew towards Naruto her palm outstretched glowing with chakra. Knowing if he let her palm touch him it would be over Naruto leaped back as Hinata crashed into the ground where he once stood. In the air, Naruto performed a set of hand symbols as he summoned Greed and Envy. Just as the dust obscuring Hinata cleared Naruto finished his jutsu ' Lightning Style: Particle Beam ' a thin black beam came out of Narutos mouth aiming straight for Hinata. With a purple flash, Hinata's tail moved in front of her glowing with chakra. The beam struck her tail but instead of cutting through fur and bone like buŧŧer, the beam was reflected off her tail like a ray of light into the cave wall.

Smiling at her strength Hinata launched herself from the ground through the air like an arrow aiming for Naruto. In a flash, Hinata was in front of Naruto her palm aiming to slam against his ċhėst. Bringing his two swords around he positioned Envy to block her strike and sent Greed to skewer Hinata. Almost in slow motion, Hinata saw Greed aiming at her stomach sweeping the sword to the side with her tail the two became locked in a battle of strength both trying to break the other. Hinata's expression turned grim when she saw the build-up of mana around Narutos back, she was familiar with his sealing chains and had come up with a way to counteract Naruto's jutsu. With the hand that was touching Envy Hinata sent out a pulse chakra into Naruto's body dispersing the chakra he had built up.

Eyes widening Naruto felt the foreign chakra enter his body and realized how much he had underestimated Hinata. Knowing that he would lose the battle Naruto let himself be blown back by Hinata. Naruto was spent speeding back into the ground where he bounced once before righting himself sending Envy and Greed into the ground to stop his momentum. Landing on the ground Hinata stared at the boy she had chosen to follow into the future, she grinned flashing her sharp teeth. Naruto grinned back before he rushed at Hinata and their battle started again.
