Epilogue
Kyuubi tapped his claws on the table, looking from his son to his soon to be son-in-law. "You want to mate my kit." he confirmed.
Kyuubi had been overjoyed when he saw that not only had his son become himself again, but he had decided to accept the humans as pack. They had performed the ritual then released the Biju. The Biju had reluctantly left, after being told that they couldn't kill the 'demon hunters'.
But then his son had told of his decision to mate Itachi. He had seen the agreement in the Uchiha's eyes. As he looked between them, he could see that they were perfect for each other. Itachi was also keeping his kit from dwelling over the past.
"I agree. But...on one condition." Kyuubi said.
Itachi didn't show a reaction but Naruto looked nervous. "What is the condition, Kyuubi-sama?"
Kyuubi bit his thumb then smeared it over Itachi's eyes. Itachi squeezed his eyes shut the opened them again to reveal a different Sharingun. Each point of the demon wind shuriken had a spiral.
"Eternal Mangekyo. My most perfect creation." Kyuubi gave Itachi a firm glare. "The Eternal Mangekyo will give you immortality like the kit and myself. I expect you to take care of him and not misuse it like the other Uchiha's of your clan."
Naruto was grinning, joyful, and even Itachi smiled. The couple hugged, determined to never be parted. Kyuubi chuckled. "I expect some grand kids."
Naruto stared. "Tou-san, I'm a boy. I can't get pregnant."
"Yes you can. All demons have the ability to be impregnated."
Naruto gave him grin as bright as the sun. He was really glad to have his kit back, he thought as he hugged his ray of sunshine.
