This is just my Kurama and San/Youko and Moriko version of the Yu Yu Hakusho movie: The Poltergeist Report. I would've tied it into my story "Eternity", but I was unsure of the time frame, and how I would fit it in considering the way I'm telling it and how it will continue. I know it's after the Dark Tournament. However, the plans I have for San wouldn't have it make much sense, so let's just pretend this fits in somehow :). I own my own characters and ideas. Now, that being all said and done, here we go...
...
The sun shines brightly, making San feel as if it was going to be just another ordinary day. Well, as ordinary as it could be living at the temple. It used to be quiet, peaceful and lonely, until a boy named Yusuke Urameshi started training here. This was Genkai's temple, and she was as much of a student as Yusuke was. He was the Rekai Tantei, sent to Genkai's temple to learn her signature move, the spirit wave. Although San had been living there for seven years prior, she was not the one destined to inherit this gift. She instead got the rest of the Genkai's power, which was more than what she needed. She sat up in one of her favourite trees of the forest that seemed to surround the temple. Her view was pointed at the lake, and she sighed contently as she observed the way the sun hit the water. It seemed that today she was living in the past, something she hadn't done in a long time.
San Chiya was her full name, but she was better known as Moriko Chie, a wolf demon, who had tawny hair and tawny eyes. San was her human name, given to her by Genkai, since as a human, she drew her powers from the sun. The wolf demon trapped inside of her, Moriko, used to be the ruler of the wolf clan, back in Makai. A false accusation and framing took place eight hundred years later, and she was banished from her land. She fled before she could be beheaded, and found a new den far away from the realm of the wolf clan. She then met Youko Kurama, who tried his hardest to steal her treasure. One day, members of her former clan had found and kidnapped her. She was actually ashamed that they had managed to do it, but realized now that it was necessary. The legendary bandit, Youko Kurama, had come to try once again to acquire the treasure that she kept with her, the seal of the wolf clan. He tracked her down and rescued her, realizing that he had fallen in love with the demoness. They mated, one like none other. She was a wolf, and that meant she mated for life. The fox was perfectly alright with that. Centuries later the two legends were pursued by demon hunters, and they had to escape here, to Ningenkai, where they would remain until they were powerful enough to emerge and return to their homeland. However, they were separated, and that's how San met Genkai.
Genkai is an old psychic who created the spirit wave. Although her name was feared among all youki, she took care of San. When she landed, she was but an ordinary wolf that hit the ground with tremendous force. She was lucky that Genkai had found her and was able to heal her. It took eight years to gain enough strength to change form. That was how San Chiya was born, she changed from a wolf into a human, one with sun touched hair and tawny eyes, not unlike the ones in her demon form. Genkai put spirit cuffs on her to help get her powers stronger when she needed them, seeing as now she would use reiki as opposed to demon energy. San still has these cuffs on today. It has been seven years, and everyone fears what the eruption of energy that could come out of her. She only trained and got much stronger with the cuffs on, so taking the handicap off could cause devastation to anyone within a ten mile radius. This was something San feared, hurting one of her many friends. There was no telling how much power those cuffs were keeping at bay, but she knew that she would have to remove them one day, when the timing was right. She was certain that once the cuffs were removed she would be able to emerge once more into her demon form. It only took a sufficient amount of energy, like when her mate had made his first appearance since the two of them were separated.
Seven years after she had changed into a human, she met a red haired boy named Shuuichi. He wasn't an ordinary human though, she could smell the demon lying within him. She followed this mysterious human, and discovered his real name was Kurama. She had saved him from a youki that was trying to attack him, in her wolf form of course. Kurama led her to Hiei, a small fire apparition with a jagan eye. The two of them teamed up with another youki and stole three artifacts from the Rekai. After that, she saw Yusuke Urameshi for the first time, on his first mission. San kept an eye out for him while continuing to follow this Kurama demon. She watched as Yusuke defeated Gouki, made a deal with Kurama and then proceeded to defeat Hiei. She was truly impressed, and continued to observe. Yusuke had come with Kazuma Kuwabara to the temple to win Genkai's tournament. Yusuke ended up the victor against a youki called Rando, and that was amazing. So the Rekai Tantei and San trained together under Genkai, Yusuke receiving quite a load more than San herself. She followed the team, Yusuke, Kuwabara, Kurama, and Hiei, knowing that they would lead her to her mate. It wasn't until the Dark Tournament that Youko appeared. Kurama was fighting his match, and his opponent had used some sort of magic to reverse Kurama's age. In his unique position, he instead reverted back to his demon form, Youko Kurama. His powers came out in such a thunderous way that it caused San to change as well, back into Moriko. She smiled, remembering that day, and how in all the years he had never changed. She loved him more than she had ever loved before in her life, and would continue to until the end of days. She knew that he felt the same, and it was proven to her when he discovered that she, San was indeed his mate Moriko. The two of basically continued where they left off, and assisted Yusuke with his missions. They would return to the Makai when Kurama's human life was done with. San was okay with that, wanting to stay with Genkai herself.
