Miyuki and Kasha, Fraturnal twins,were born some odd 300 years ago  compared to the TAW timeline.
Kitsune born, the inseparable twins grew up in relative isolation with their mother, father and grandmother managing the Aokigahara Shrine. Their father a human was the only one allowed to leave the shrine for work. At a young age both showed promising gifts that their grandmother began to focus on improving. Miyuki clearly stronger with elemental arts,spiritual mediums, tactics and shinobi technique. Equally being a kitsune, Miyuki was able to sense and see other paranormal elements. The pair lived carefree together never one step farther than the other and had expected to always be that way, sadly it was not to be.

Due to the nature of their clan, the youngest child inherited the role as vessel for the goddess Inari. This divine punishment has been in their clan's blood for years beyond comprehension, the goddess passing from mother to youngest child again and again with seemingly no end. Miyuki in her youth tried to aid Kasha in escaping their home, naively believing in doing so she might escape this fate however they were caught. Not long afterward Miyuki and her father were forced to leave the shrine. Miyuki becoming severely heartbroken from being separated from her twin. Once settled in their new home, Miyuki made a contract with the goddess Amaterasu and gave her maidens pledge in return for the goddess's aide in freeing her sister.

Due to his profession, Miyuki relatively had to want for nothing, however what she wanted she couldn't have. Outside the safety of the shrine, Miyuki learned quickly to hide her ears and tail as well as never displaying her abilities. To further blend in she adopted the use of dark colored wigs and contacts. For ten years Miyuki lived a relatively boring life as she passed off for human, close to her seventeenth birthday Miyuki finally moved out from her father's home into her own apartment. Though it was being paid for by her father Miyuki took on a hostess position at a local Hostess club using the stage name 'Momo'. Around this time Miyuki also began other lines of work which would later become the foundation of the Kitsune Udon.

Life seemed good for the independent Kitsune when her twin Kasha appeared on her door step. Though a little turbulent at first the two soon were happily living together. Doing everything from attending highschool, spending time with their father, working cases and of course, getting into mischief. For reasons that are still unclear Miyuki and Kasha were abducted, not to be heard from again until they were discovered in a sealed room behind the mansion. Once revived the twins were shocked to discover all that had changed and how much of their old life they had lost. In time they would adapt and begin to make a new home and family with not only Cheryl but with Isis, their fiancee, and her family. Until Inari is freed from her twin Miyuki continues to stay a virgin which makes things interesting for her relationship with her twin, Isis and Hi'saa.

Miyuki comes off as very cold and serious but is quite warm and sweet when given the chance. Though she can sometimes seem harsh and quick to anger towards her twin, Kasha is very much the world to Miyuki. Miyuki is very moral when it comes to how she conducts herself, insisting on working of a debt and never accepting money outright however that is not to say her kitsune nature doesn't lend to a small amount of mischief making.  Miyuki's morality also extends to her 'Prince mode' where she will embody the traits expected of a fairy tale prince. Miyuki is quick to be embarrassed and flusters when subject matter becomes sexual or involves her body. However like her 'Prince Mode' Miyuki has a Submissive and Domm mode as well which seems to be exploited by the few who know how to.  Miyuki is regularly teased about the 'harem' she's created which she honestly doesn't know how it began but she tries to make sure it doesn't grow. If it stays that way or not remains to be seen.

After the events of The Alien Wars 5, the Nue family had many more kids. However, due to those events, the mulitverse was destroyed and Centerpoint was sucked into a blackhole. 20 years later, destruction began to occur slowly and Yuki, the daughter of Taiga, discovered what she called a mirror universe attached to their's. Two groups traveled over to that universe. Miyuki was part of the group that went over - though there are events still being documented before she went over. To see the events after she went over, see Duality.
