Alright, lets see if this works!
Can become attracted to both sexes though she's mostly unconcerned about such manners.
Domestic Servant on the rise.
No nonsense, serious and focused. Mai is a person that pursues her objectives with the greatest focus and resolve she can muster, letting nothing get in her way. She is industrious, inteligent and good at maintaining a schedule to take care of work in the most efficient manner possible. While she can be sarcastic and mean to those around her, she can quite easily come to secretly like the good parts of the people around her, and holding their best interests in mind she can be surprisingly caring and attentive. Still, underneath this lies a layer of ruthlessness coming from a fervent desire to live and live well. Mai is quite proud, which is a bit of a weak point of hers as well with having a strong wish to rise in life and be able to indulge in the delights of high life.
Mai comes from another country, having been sold into slavery at the tender age of 7 to pay off the debts of her family to a nasty crime syndicate. She came to China by boat after only two months in her new life, to be sold in the markets of the mainland to a new life of service. The beginning was hard, but following the advice of a young lady in the markets after she got a beating from crying... Mai slowly learned how to close off her heart and focus of becoming what people wished of her. She got sold to a wealthy demon where she spent most of what remained of her childhood. There she learned to clean, to cook and do all sorts of housework... and she did it better than most anyone around. She was diligent and utterly selfless, her greatest skill coming from learning what the Master might need before even he knew it, learning all his different cues to provide the best service... learning to speak as he might like best, how to walk, how to act. As the years went by, the young girl became the favorite servant of the household. She was treated well and never got beaten... which to the girl was the best life she could know at the time. However, things changed one fateful day... When her owner rewarded her with a sweet exotic treat he had recently bought at the market. To many it would have been just a frivolous expense... but to Mai, it was a moment that opened her eyes and changed her life. As she delighted in it she realized... that she didn't want to spend the rest of her life at the whims of other as a servant, not even a spoiled one. She wanted to be one who could eat such treats as she wished, enjoy long warm baths, be clothed in fine silk... She realized how the Master looked as her as she grew older and just a bit more feminine with every year. She didn't act immediately. She didn't even start a plot of any sort. She just went about her life... but two months later, she found herself shaving her Master and idly realized that there was nobody on her way if she attempted to escape right now down the servant exit. She knew where everyone would be stationed, where everyone was working... and thus, with the knowledge that she could escape she acted. She slit the throat of her Master with as much excitement as she cut his beard and then made her escape. She took off her collar with the Master's keys, and then took the time to dress in outside clothes and cut off her own hair before making her way out into the city.
A young girl of 14 she was. She spent only two nights in the streets, doing her best to survive alone before she passed herself off as a boy and enlisted in the army. She was slim and while she was maturing into a woman she could still easily pass off as a member of the other sex. She put what she learned in the mansion to good use and thus was able to thrive in the military world. Obeying orders was near second nature to her and she was not unused to hard work. Of battle she knew a lot less, but then again, most all recruits were bad at it anyway. Mai worked herself hard, trained longer than most people and dealt with each of her superior officers as it was necessary. In this manner she managed to remain and indeed, thrive in the army for five years before her ruse was finally discovered. A keen commander managed to finally look through the disguise she had perfected for many years, her developing body betraying her. Still, he was not an unkind demon... but a strict one. He would not have her continue her service... but did arrange for her to have a place to go. Thus, Mai returned to a life of service once again... but this time, to Lord of a much higher prestige than the slave master demon she once served. Two months back she was recommended by the commander to become a servant of the royal palace, arriving once again in a nostalgic guise of femininity. Her hair had grown during her time in the army and she wore it in a convenient ponytail as Mai once again took the mop and rag to do her work as she did it best. The luxury wasn't hers as a servant... but it was a step up from the muddy life of a soldier and she enjoyed a freedom she didn't have in the old manor. She promised herself that little by little she would make her way through the world, by giving it her best and working hard to attain such a good life. She's rather new to the palace... but so far she had distinguished herself by her way to make things work out, tireless work and somewhat harsh manner and sharp tongue.
Not powers, per se, but Mai is a skilled fighter and martial artist from her years out in the field. She's an excellent cook and in general excels at most housework. She's quite observant and intelligent, able to figure how things and people work if given enough time, though she's more than a bit clueless about the field of love and romance.
She loves sweets. Exotic treats and money are a very weak point of hers.
