(An Inu no Taisho story)
Sakoda Nakamaro was Lord of the Northern Lands at the same time as Inu no Taisho was Lord of the Western lands. Lord Nakamaro was mated to Ina they are Northern ice Inu demons. They had a daughter that they named Oujo (meaning princess) during the Great War. A deal was made with Inu no Taisho the mating of his daughter with one of the Western Lords. It didn't matter if it was the great dog General's son or a lesser Lords son. What did matter was the deal was meant to provide protection to the Northern Lord. Inu no Taisho gave Lord Nakamaro a necklace with a crescent moon pendant on it. The necklace was to be given to her when she had her first heat. This would give her protection from all that wished to harm the Northern princess within the Western Lands. That left General Inu no Taisho with the task of choosing a suitable mate for her.
As the war continued, and the threat to Lord Nakamaro's family increased when his daughter was only a toddler. They made a trip to see Father Time he owed Lord Nakamaro a favor, so he took them to an enchanted time well he created in the Western lands the well had taken them 500 years into the future from that time. He warned Lord Nakamaro not to allow the girl near the well at any time as the well could send their daughter back in time and not allow her ever to return.
Lord Nakamaro quickly went to work for a company that took him, and his family overseas to America. He had been looking for any and all jobs that would take him away from Japan he didn't want to risk losing his young daughter down the well with no hope of ever getting her back. There they changed their young girl's name to Sarah (still meaning princess). They all hid their demonic traits leaving Sarah to grow up thinking she was in fact human like everyone else. He had her home schooled because she was a demon and aged more slowly. He didn't want his daughter wondering why she looked so much younger than all the children her age.

Now Sakoda Nakamaro had to move back to Japan to finally own the company that he initially worked for many smart investments had made him a wealthy man. Their daughter Sarah now looked 16 her father had wanted her to know Japanese as well as English. She was allowed any activity that let her interact with others her age as long as her father approved of it. She took dance, gymnastics, and all forms of Karate, baton twirling, as well as Japanese Katana sword fighting. When they had moved back to Tokyo, Japan. Sakoda Nakamaro immediately enrolled her into Tokyo High school. He then got an apartment near the school until they could find a house to buy. At this point, he no longer feared an obvious age difference between her and the human children. So it was now safe to allow her to attend a real school. He also knew that should she find the well which he doubted even existed anymore that she could take care of herself should she find herself back in time. He also knew the well was in the West and her necklace assured her protection in those lands due to the deal he had made with Inu no Tashio.
