Sam saw Miles go down and rushed over to him. "Miles? Miles, can you hear me?" he asked shaking the unconscious blond.
Mikaela came over and kneeled beside him. "Sam, stop freaking out." she scolded. "We'll carry him to the nurse's office. Okay, so get his right, I'll get his left."
They both maneuvered Miles until he was upright with Sam, and Mikaela supporting his weight. They hurried into the school, Miles' feet dragging on the ground.
Miles stared up at Kyuubi dumbly. "I'm a reincarnation?" Kyuubi nodded. Miles furrowed his brow. "Wait, what's a 'Jinchuuriki'?"
Kyuubi sighed. "It means, 'The Power of the Human Sacrifice.'"
Miles paled. "I don't like the sound of that." he said nervously. He then realized something else. "Those doors, are they-"
"-your life memories? Yes." Kyuubi nodded again. "The old decaying doors are of your life as Naruto, and the shiny, newer ones are your current life."
"And the golden one?" Miles prompted.
"Your most precious memories." Kyuubi said. 'Which is kinda sad since there's only one gold door.'
"C-could I see what my past life was like?" Miles asked.
Kyuubi frowned. "That may not be such a good idea."
Miles stared at him curiously. "Why? How bad could my past life have been?" he shrugged.
Kyuubi's eyes glowed as he stared down at the blonde with utter seriousness. "Think of all the times you've been picked on, bullied, been beaten up by your tormentor, and times all that by a hundred times over."
Miles shook slightly. "You can't be serious. What did my past-self do that was so bad?"
Kyuubi looked at him sadly. "Living." he looked away. "Jinchuuriki are generally lonely, and hated people. They are hated by the very villages they are protecting. Those that are trained to be living weapons are feared. Those that aren't, are hated and have constant attempts on their lives." Kyuubi looked at him. "You, Miles, were in the second category."
Miles frowned. "So I guess both my lives suck then." he grumbled.
"Not necessarily." Kyuubi interrupted. "After a while, you got friends, but..."
"You don't have to tell me." Miles interjected seeing that whatever Kyuubi was trying to say semed to make him uncomfortable. "But is there anything else I should know about?" he asked.
Kyuubi grinned. "Two words: chakra, jutsus."
"What?" Miles asked blankly.
"Perhaps I should show you first." Kyuubi's form suddenly began to change. It became smaller and more human-like. Soon, where, Kyuubi once stood, there was now a rather attractive teenage boy with spiky red hair, pale skin, red slitted eyes, and wearing a simple red T-shirt and black jeans.
"Kyuubi?" Miles asked both dumbfounded and amazed.
Kyuubi smirked, his fangs showing. "Yup. This is my human form." he said, his voice not as deep as before.
"Um, how is you changing into your human form going to help me with jutsu and chakra?" Miles asked tilting his head.
Kyuubi shrugged. "It doesn't. I just wanted to show you my awesome shapeshifting ability."
Miles fell back anime -style and stood up to glare at Kyuubi. "That's it?"
Kyuubi smirked again upon seeing more of Naruto showing in his current self. "Easy now." A red misty energy appeared around Kyuubi. "This is my chakra; demon chakra." he emphasized. "As my Jinchuuriki, you are able to acess it and use it at your disposal."
"There's a "but", isn't there?" Miles asked frowning.
Kyuubi nodded. "Correct. Your current chakra reserves may be the same as they had been when you were Naruto, but seeing as you have no training what-so-ever about this, it would catatrosphic if you were to use my chakra."
"So, what do I have to do then?" Miles asked scratching his head.
"Your spiritual and physical energies which make up your chakra must be in unison, and currently you have quite a lot of spiritual energy." Kyuubi said. "So you must build up your physical energy to even it out so to speak."
"Um, how do I do that?" Miles asked.
A sadistic grin came over Kyuubi's human face. "You must train."
"Train?" Miles asked feeling unnerved by the grin Kyuubi had on his face.
"Train, exercise, work-out, there all the same." Kyuubi shrugged.
"Well, what kind of training?" Miles asked.
"The basics; running, push-ups, sit ups." Kyuubi counted off. "Oh, and you'll need chakra weights."
"What the heck are those and where am I supposed to find some?" Miles asked.
Kyuubi sighed. "Simple. You buy four sweat bands for your wrists and ankles and I'll put some of my chakra into them and presto; instant makeshift chakra weights." Kyuubi then peered closely at the blonde. "Anything else you want to know before you have to wake up?"
"Um, yeah. Will I still be able to communicate with you, or will I have to come here?" Miles asked.
"You will be able to still communicate with me." Kyuubi assured. "Now, it's time for you to wake up, Kit."
Miles barely had time to blink before he found himself in back in the real world and in the room he had come to familiarize himself with: the nurse's office. He had always had an intense dislike for hospitals and their staff. With what Kyuubi told him about Jinchuuriki assasination attempts, it only made sense for him to mistrust doctors.
Miles sat up and twisted around so that his legs were dangling over the edge of the bed, the springs creaking in protest. As if summoned by the creaks, the nurse-with her shoulder-length black hair up in a bun, and white uniform-came in and, to Miles surprise, Sam was right behind her.
Sam looked relieved. "Miles, you're alright! You are alright, aren't you?" he asked nervously.
Before Miles could reply the nurse realized what Miles was doing. "Oh no young man, you're staying on that bed until I clear you."
Miles obediently stayed put, but he did protest. "I'm fine, nothing's wrong with me."
"If there was nothing wrong with you, then you would not have passed out in the student parking lot." The nurse retorted. Miles mentally glared at Kyuubi. The nurse looked over at Sam. "You!" Sam jumped. "What are you still doing here? I'm with a patient, now get out of my office!"
The nurse was known for her 'take-no-crap-from-anyone' attitude, so Sam ran right out of the office. 'I swear that nurse is as scary as Ratchet!'
Miles watched Sam run away and groaned internally. 'Great, just when I thought he had some sense of loyalty, he runs away!'
'Look at it this way kit. You've always got me.' Kyuubi said.
'Yeah, but you don`t have much of a choice in being here.' Miles thought. 'I want a best friend who won't blow me off for a girl-or kick me out of a car and make me walk home!-and maybe someone who will just accept me for me.' he added sadly.
'Yup, just like him.' Kyuubi thought recalling Naruto's dream of being Hokage to earn the respect and recognition of his village. 'Too bad you died before you could achieve your dream, Kit.'
The reason Kyuubi is being so nice-for him anyways- is because he feels guilty about the life that both Naruto and Miles lead, and because he feels resposible for Naruto's subsequent death.
