Prologue: The Oracle

From a young age, something was off about Nana Hisakawa. She was a sweet girl but her mind obviously wasn't all there. There were times that she would be in a catatonic state, not registering anything going on around her.

There was a blond man with blue eyes wearing a suit. His words were foreign but he seemed to be in a meeting with six other men. A blond in a military uniform, a blue haired man that looked like a nobleman, a scowling man with pink hair, a smiling Japanese man, a teen with short green hair and a man with short white hair. Nana could recognize a boot shaped country on a map, one that the young girl could recognize from her geography class as Italy.

Visions often overwhelmed Nana in her youth, her mind stuck either in the past or the future. Her parents were at their wits end. "I just don't understand! The doctors say that physically there isn't anything wrong with her. But her episodes are getting harder to snap her out of!" Isao Hisakawa exclaims, banging his hands against the table. Nana's parents had sent her to every psychologist they could find but no one had a clear answer for what was happening in her mind. Victoria Hisakawa sighed. "There is one possibility that we haven't considered. She could be a mutant."

Mutants in Japan were rarely spoken of, treated with the same disdain as people had for the yakuza and gaijin. They were considered outsiders and avoided like the plague. When Victoria had first been assigned to the county, she lost count of how many times people looked down on her due to being American. Thankfully Nana had taken after her father's side of the family when it came to her looks.

The Hisakawas watched their daughter stare blankly out of a window with a dazed expression. "There's no cure for mutations. No one deserves to suffer as a pariah over something they can't control." Jade says, a hint of irritation in her voice. It hurt to see her daughter hurt and not be able to do anything about it.

Nana watched a boy that had a strong resemblance to the blond Italian, cowering from a group of bullies. He forced back his sobs, his entire body bruised and bloody. "Why? If I'm so useless, why won't they leave me alone?" He whimpered, holding his side.

Tears ran down Nana's face, desperately wishing that she could help somehow. She couldn't tell whether it had already happened or would happen in the future. All she knew was that her visions tended to be focused on herself and the people close to her. That blond man and the crying child were connected to her, she just didn't know how. "Nana? Sweetie are you alright?" Her mother asks, Nana forced herself to smile. She couldn't bring herself to burden her parents, they were already trying so hard to make her childhood normal.

Around this time, Charles Xavier was beginning to make plans for a school dedicated to training young mutants to control their powers. The man was surprised to get an international call originating from Japan. "This is Professor Charles Xavier. May I ask who is calling?" There was a brief moment of silence on the other end. "I am Victoria Hisakawa, I heard from one of my sources you were planning to build a school for mutants." A woman's voice states.

"I assume you have a child in need of instruction." Charles states, the voice on the phone sighed. "Professor, we have tried everything to help our daughter. The people here aren't tolerant of mutants and I can't bear to see her suffer for something she can't control." She says. "Can you tell what sort of mutation your child has?" Charles asks. "It seems to be some type of clairvoyance. The visions seem to appear at random and it's impossible to get her attention during one. It's gotten to the point that we've pulled her out of school." Charles nodded to himself, it was children like this that he wanted to take in.

"I would like to meet this child first to see her powers for myself. Would you kindly give me your address?" He took out a notepad, writing down the woman's contact information. "I assure you Miss Hisakawa, we will do everything we can to help your daughter. I wish you a good day." He hung up the phone and sighed, massaging his temple. Japan wasn't known to be very friendly to foreigners and the woman spoke fluent English with an American accent. The poor child would be alienated if her powers weren't controlled. Now how was he going to handle this? "You seem to be pondering something old friend." A voice noted in amusement. "Erik, not that I don't appreciate the visit but I would appreciate a knock to announce your presence. It seems we're visiting the land of the rising sun."

The Hisakawa residence was on temple grounds, the husband a priest for the small town. Isao was a jovial man with his brown hair in a buzz cut, his eyes a light brown. The mother, Victoria Hisakawa, was more closed off. The woman regarded everything with caution, but her thoughts reflected her concern over Nana. The girl herself had a sweet disposition and was excited to have guests. "Nana, do you know why these gentlemen are here?" Isao asks, Nana's eyes dimmed. "A… school?" She asks slowly, her words sounding as if she was struggling to speak. She blinked, shaking her head vigorously and smiled. "You're fighting for mutants like us to receive equal treatment to normal people. But you have different ideas I think." She says thoughtfully.

"Erik! There is no need to use such violence! You are only confirming the fears that others have about mutants!" Charles exclaimed to the man now wearing a metal helmet and billowing purple cape.

"Your approach is too soft Charles. We are better than them, we shouldn't be begging humans for their acceptance. Have you forgotten that the government only views us as weapons to be disposed of once our usefulness is over? They're even forcing us to register ourselves." Erik says coldly.

"Not all people are like that Erik!" "Not everyone is a humanitarian like yourself. If I have to use force to make life better for all mutant kind, then so be it."

Nana really didn't understand what was going on in the future, but it looked like the men were no longer friends after an argument. "That… is correct." Charles says, dumbfounded. Erik was silent, wondering how much the child really knew. Charles prodded into her mind and was amazed at how active it was for such a young child. "I can lessen the intensity of the visions but she'll still have to cope with them in the future. I'm afraid that I can't stay long in your country." He states, Victoria sighed. "What do you think Nana? Would you like to stay in America?"

Nana Hisagawa became one of Professor Xavier's first students and became one of the X-Men that worked behind the scenes as The Oracle. As long as the person was someone she was close to, she could briefly glimpse into the future of their mission. Jean Grey treated her as an older sister and Nana would often do the chores around the mansion. After she turned twenty she abruptly decided to retire and go back to Japan. She promised to keep in touch with the group through letters and the occasional phone call. "You will always be welcome here Nana. I wish you luck in your endeavors." Professor Xavier says, Nana hugged the wheelchair bound man. "Thank you for taking me in all those years ago. We will meet again professor, I can promise you that." Nana says with a warm smile.

Nana was a bit skeptical about Iemitsu when she first met the man. He had been raised in Italy but had Japanese parents. There was a gentle warmth that seemed to radiate from him, even if he came off as being obnoxious at times. She knew that she could change her own future if she ignored his courting, that the crying child she had seen in the future wouldn't exist. The boy wasn't born yet and she already knew that she would do everything in her power to keep him safe. "May I have your number ma'am?" Iemitsu asks with a cheesy grin, Nana giggled. She knew the loneliness she would experience in the future if she married this man but she couldn't bring herself to care. "Of course. Would you mind walking me back to my apartment?"

Six months later and Nana found herself looking back to her whirlwind romance. Iemitsu was a devout Catholic so he held off on the more sexual part of their relationship until they were married. The man wouldn't hesitate to murder someone in cold blood yet sleeping with a woman before marriage was apparently a taboo he was unwilling to break. "Does he honestly think that I wouldn't notice being a construction worker was just a cover story? Your father is well meaning but a bit of an idiot." Nana says, placing her hand on her stomach. She honestly hadn't expected to fall pregnant so quickly but Iemitsu was very… passionate. Now Nana and Iemitsu officially lived in a small town called Namimori, a quaint place the couple had fallen in love with.

Her visions involving her son became more clear and she was worried for his future. Tsuna would be a bright child, later crippled by Iemitsu's boss all because he had a fire mutation. While Nana was aware the mental block the professor put in her mind was to keep her from being overwhelmed by her powers, her glimpse into the future showed how much pain and suffering her son went through when he was sealed. While he would eventually recover, her little boy would be permanently scarred. She refused to let that happen.
