Prologue
Disclaimer: I don't own Naruto, but I do own the plot
The story starts: the night of the Kyuubi attack, the fourth hokage just sealed the Kyuubi inside of Naruto.
The fourth stares at his sleeping son, who has blonde hair like him and also has three lines on his checks, he is wondering when he will appear. Then a man with short red hair dressed in a traditional red kimono stand in front of him. "You," he says, "What have you done to me!" The man looks at himself turning in circles.
"I gave you a human form, Kyuubi," the fourth hokage says to the Kyuubi, and he is mad.
"I thought you sealed me in your brat," Kyuubi said and pointed to the blond infant.
"I did, but I gave you enough chakra to sustain that body of yours and to raise my son," he said.
Kyuubi thinks, "He must be joking," then he says, "What make you think I will raise him, do it yourself," the fourth shakes his head and Kyuubi lifts him up by the front of his shirt, "you're giving me your son!"
"Now he won't be alone," was the last thing the forth said before he died. The Kyuubi throws his dead body and walks to the boy who was crying.
Kyuubi puts his hand down and the blond child starts laughing, Kyuubi smiles from amusement and picks up the boy. Then thinks of something, "I don't know the kids name," he says and looks ticked off at Minato. Kyuubi checks the blanket to see the name Naruto stitched in it, he sighed with relief, he didn't want to name Naruto. Kyuubi could hear footsteps coming from the forest so he runs to the Leaf Village. Kyuubi goes to the abandoned Uzumaki complex; he walks into the hokage's old home and into Naruto's room that his parents had already made for him. Kyuubi puts him in the crib and goes into his new room, Minato and Kushina's old room. Kyuubi falls asleep and starts his new life with Naruto.
Five years later
Naruto is running home and away from an angry mob calling him a demon child, he turns down an ally way, but runs into a dead end. He looks around for an escape way then he sees an infant covered in red chakra hidden in a box and hugs the girl to hide her light, Naruto waits with her until the mob gives up and leaves with the girl in his arms.
Naruto walks in and says, "I'm home daddy."
"Welcome back, Naruto, I'm making dinner," Kyuubi says string the soup. Naruto walks in to see his dad in an apron with his long hair red hair in a ponytail, Naruto tries to walk away until he hears, "Who is the child on your back Naruto?" Kyuubi says without turning around.
Naruto froze and thinks, "I am in so much trouble." Naruto turns around and says, "Umm I found her in a box on my way home and she was glowing red like you when I hand dyed your hair black for week." Kyuubi remembered having black hair when Naruto was three and how he showed him why not to anger him.
Kyuubi turned around and says, "Hand her to me," Naruto hesitates and Kyuubi makes a 'give me' jester with his hand. Naruto walks up to him and he picks her up, she was wrapped in an orange blanket and had red hair down to her shoulders, Kyuubi looks up at his son, "Naruto, where did you find her again?" He asks his son.
"In a box down an ally way," Naruto answers.
"Why were you in an ally?" Kyuubi asks with great concern. "Where those villagers chasing you again?" he said infuriated. Naruto nodes, Kyuubi makes a mental note to walk Naruto home when he starts at the ninja academe. He looks down to the child in his arms and at Naruto's depressed look. "So," Naruto looks up, "what should we call her?" Naruto's face lights up with joy and he runs to the window, "hey, I asked what to call her!" Kyuubi says to his son.
"The moon is pretty tonight, the stars are so bright, and the sky is really dark. The night is so pretty tonight especially with the full orange moon," Naruto continues to look out the window.
"So her name is Yoru?" Naruto nodes, if Naruto wants or thinks something he sometimes he won't say it; instead he will coach his dad into thinking of it. "Yoru means night so her full name will mean night tailed beast.
Naruto nodes, "she is now Yoru Bijuu, like I am Naruto Bijuu and daddy is Kyuubi Bijuu," he says with a smile. Kyuubi puts Yoru in Naruto's old chair and has him sit in a normal one, "yay it's time for food, thanks for the meal." Naruto says and eats ask Kyuubi bottle feeds Yoru.
"Naruto," Kyuubi says and he looks up, "if you wanted a sibling we could have talked about it but if you bring another random child in this house again and expect me to raise them then I will give them to the Anbu, understand?" Naruto nodes, he doesn't like the Anbu because if it was up to them then he would either be dead or in prison, that's what his dad told him anyway. "If your finished then get ready for bed ok, Naruto," he nodes, puts his dishes in the sink and runs to his bathroom to get ready. Kyuubi looks at the girl in his arms, no he looks at his new daughter. He walks up to the calendar and writes down on October 10th Naruto and Yoru's birthdays. "If he wants her to stay then he will have to learn how to share his birthday," Kyuubi chucked to himself. "Naruto are you ready for bed yet," he screams down the hall.
"Yes daddy," Naruto says and runs to his dad and takes Yoru from his hands surprising Kyuubi, "Yoru can sleep with me!" He holds Yoru tightly and runs to his room.
"Naruto don't run with her in your arms you'll drop her, we aren't dropping this one!" Kyuubi screams chasing after Naruto, Kyuubi catches Naruto in Kyuubi's room already asleep with Yoru in his arms. Kyuubi lies down next to them and pats Naruto's head.
