She felt the cool air hit her face as she jumped to the ground from the last stair of the airplane staircase. Other adults stared at her discerningly, probably thinking of her lack of maturity. But what could they want from her? She was only sixteen, and still in bloom, but opening more and more everyday.

She had always wanted to go to Japan. The pictures in books looked absolutely stunning, and she couldn't resist a traditional sushi plate in the States. But those weren't the reasons she came. This was no vacation. She may not live to see seventeen.

She had sensed an incredible power coming from this area. It would mask itself, and reappear within minutes. Even from her old apartment in Chicago, she could feel the spirit energy coming from this city. It was so distinct, and not just from one person, either. (end flashback)

She walked the streets, imagining them as her ancestors had seen them-Goku, Gohan, and Goten. They were all long gone now, but the Saiyan blood still ran in her veins. She didn't care if she was only 1/10000000000 Saiyan. All she cared about was having a small part of a great legacy within her. Even though she could stare at the full moon with no adverse effect from her saiyan heritage, she still could feel her blood boiling at the sight.

But these powers she sensed...they were different...almost human-like...but...not entirely. She knew they had to be different, like her, but she hoped they were not evil, as her visions had told her. She didn't want to have to kill again.

(begin flashback sequence)

It had already been 6 years since the accident. She was jumping on the trampoline at the gym, and suddenly, it all went black. She dreamt, and she felt herself growing stronger, like something had snapped within her; like some limit had been crossed. When she awoke, she found herself on the cold floor, with twenty eyes staring at her. She sat up, and rubbed her head. Amazingly, no blood, but the people told her she was out for three hours. She went home that day, with a bump on her head, and a candy from the gym nurse. But she didn't know why she didn't hurt. She did hit concrete, after all, and the nurse was amazed. "A miracle, Kelly, a miracle," the nurse said as she left. "Yeah...a miracle," she thought, as she held her Crucifix in her hand.

Ever since that day, she had seen things, and had supernatural abilities. It started out as a large increase in strength, and after 20 broken dishes, she decided to train to control her new prowess. As she trained, she could control it, and she became stronger and stronger. She could run faster than anyone she knew, and soon, she learned to levitate, and, eventually, fly. Her spirit energy was so intense that she could support her own weight with it...but only when no one was watching...and usually during her midnight walks.

She wasn't afraid of being mugged or anything, even on the city streets of Chicago, because she had discovered that she could feel when a person approached, even from afar, and she could tell how strong they were, and the nature of their heart, unless they were truly powerful, and that remained a mystery. Soon, she could feel powers from all over the world. She felt people with power levels that were remarkably higher than others, but still, the four strongest, by far, were in Japan; Mizkuzi City, Japan.

Soon, she became very skilled in the martial arts and in spirit energy attacks. It frightened her at first, but soon, she learned to control it. (And...she learned the fine art of wood putty after all those holes in the wall from misguided ki cannons.)

She also developed a telepathic skill with people of high spirit energy. She mentally talked to people in China...but she never understood them...and felt them become frightened...so she stopped...but she still had mastered the technique.

She began to not only sense the power in Japan, but see a shadow of the figures as well. One was a short, thin, spiky-haired male; the other, a male, she guessed, was very tall, with uncontrollable hair; yet another was shorter, but had longer hair-who looked to be a female, but she sensed a male quality about him; and the last, and perhaps the most powerful, was rather tall, but not the tallest, and had slicked-back hair...he had to be a guy. She wondered who they were and if they were trouble or not. But she just brushed it off.

One fine summer evening, under the pale light of the moon, about 2 years ago, she was training. The moon provided enough light to spar with an imaginary partner, but while she was training, something inside her clicked. She suddenly became angry, and she powered up like never before. It felt like heat was singeing her very skin, and she worried if she could consume herself with her power. Once she controlled the power, she realized it was lighter outside. A golden light covered the earth around her. She walked over to the stream, and saw that her hair had turned to a gold color and was emitting a strange light. Upon closer observation, her eyes were now blue, not green, like normal. She decided to look up her family history and see if this was in the line...she had never heard of this before.

Genealogy had always fascinated her, but she now had an urgent reason to know her family history. She wondered if there was more power to grasp, and if this was her birthright. Her parents never showed any significant strength...but they never got injured like she had...and that was, after all, what made her click...

She discovered that about a millennium ago, her ancestors, Goku, Gohan, and Goten lived. She found an old photo book, and saw that they too had transformed, and she read Chi-Chi's diary...blaming her son Gohan's Saiyan heritage for his being a rebel...

Their address was in Japan, in the hills...could there be other Saiyans like herself there? Could those immense powers she felt be Saiyans? She read that most Saiyans were evil, so would she have to destroy them? What if they had surpassed her power?

Upon further research, she found Gohan's journal. He wrote that most Saiyans had black hair and eyes. He also stated that all Saiyans could transform into a Super Saiyan with golden hair and blue eyes. He also said that after that level there was a SS2, with more power and longer hair; a SS3, with very long hair and a magnificent prowess; (a transformation which only Goku and Gotenks had gained...whoever the latter is...) Golden Ozaru stage, in which the Saiyan becomes a huge monkey with immense power after looking at the full moon in SS3 stage; (even without a tail...good thing...she didn't have one of those...) and SS4, a stage with pink body fur, and black hair. No one had gone further than that in Gohan's day...and she assumed no one ever did.

She also read about certain spirit energy, or ki, attacks. She learned them all by name, and eventually had an arsenal of attacks. She learned how to fuze, and how to create the most powerful attack, the Kamehameha.

So, she trained to control her powers, and eventually, she could go from her human state to her saiyan state, (with black hair and all...very different from her brown hair in her human form) to the SSJ, to the SSJ2, to the SSJ3, to the Golden Ozaru, (although she hated that form...it was so...evil to her) to the SSJ4, and finally to SSJ5! The SSJ5 had silver hair with green eyes, very human-looking though...nothing like the SSJ4...

Eventually, she learned to skip around levels...from human to SSJ5 to SS2, and back to human again...or any combination of levels.(end flashback)

But now she could feel the power of the four. They had disappeared for a year, when she was fifteen, and now, they were back. That is what made her come.

She walked with her hands in her pockets. Her left was fingering her favorite rosary, the green one with Irish crosses on the beads. She knew God was her ally in all battles, and that she was in Japan for a reason.

She masked her power the entire walk down the street, masquerading in her human form. She eventually came to a junior high school, where she felt a familiar power from within.

She looked at her watch. 2:45...Japan time...school would be out soon. She fingered the blade in her right pocket, her favorite knife, made out of silver. Even she couldn't touch the blade...and she had no idea why.

School let out, and Kurama walked down the sidewalk to his home. As he moved along, he caught sight of a young girl, about his age, with deep and mysterious eyes, and a supernatural power emitting from her. She looked out of place, as he did. She had an American look about her...not oriental at all, just like himself. New people to the school often asked if he was an exchange student, and he always said no, but in a way, he was...

She suddenly got a chill...he was near! She looked about the students, and caught sight of a handsome male of about 17, with long red hair and emerald eyes. He had a power emitting from him, and at this close distance, she could even see his aura.

She ran over to him, and asked if he spoke English.

"Yes, indeed, I do. As fluently as all other languages. Are you from the States?"

She answered him yes with a smile, and they talked, each wary of the other, but Kurama had no idea why he was cautious around this beautiful human. He was falling in love with her. They strolled down the sidewalk, and she pointed out the flowers and named them. He was astounded, since he was a biologist in training, so to speak. She told him she loved to study plants. She asked his name, and he said he was Minamino Suuichi. She said that she was Kelly.

They walked on for hours until he realized he was starting to plan his life around her. She was so perfect for him, but not in all ways. She was perfect for Minamino Suuichi, but not for Kurama. He would have to harden his heart, for he did not want to break his heart again, just because his soul mate was a human.

He showed her around the city, and they ate dinner together. It was the first time he laughed since their last mission to the Maki. But he knew it had to end.

As he was getting ready to leave her, she led him to a dark part of a park. It was midnight, and no one was around. "Suuichi, I love you, but I must confess, I can't love you." This startled him, and he wondered why. He listened with inquisitive ears. "I came here looking for you and your three powerful friends. I know you masquerade as a human, and that you may be evil. I came here to destroy you if that is how it is, for I am a martial artist." She raised her power slightly, as to mock a warming up sequence for a novice martial artist. He was startled as he felt her power jump to average human levels, but nowhere near his own. He asked her how she knew of his three friends, and she said she could not tell him until after they fought. He saw the determination in her eyes, and decided he could not reason with her, so he would get some exercise. He powered up a bit, and got ready to put his rusty martial arts to the test.
