Is a small child of thirteen that is partial to dark colors, her hair itself being an odd mixture of black & purple that makes her slightly different from other raven-haired girls. Generally, she seems to be very uncaring, cold, and disinterested in interacting with other people in anyway.
Jade became more 'active' during the chuunin exam of...663, was it?
Whatever year it was, it was during the exams that she went around Konoho, teaching herself what she could, getting help with what she couldn't, and made a few friends because, believe it or not, she wasn't always so evasive to interacting with others.
Two years later, she had made many friends from her village and went into the medical field, and while she had been kicked out of her home by her own mother, had found family with fellow ninja and was adopted by an older male and his girlfriend of the time, though she realized that many people didn't like her new brother..something that didn't bother her as it meant less houseguests.
During a mission with Ocosu, however, her days of sweetness came to an adrupt end when she was suddenly striken from behind and fell into a coma, a coma that lasted two months and which, during that time, many of her friends were either killed or went rogue which left her almost utterly alone. Being a person that didn't want to bother other people she keeps her distance from her last living friend and the new Mizukage.
Profession and skills
Jade is a medic, and one that is very advanced for her age, capable of healing minor to medium sized wounds, the more fatal wounds still being outside of her reach to heal without help of medical aids, even with them the chance of survival isn't yet at a high enough percent to please her.
A credit to her skill is that, at one point, she was given the chance to help Yuki, Rei restore someones voice and then take care of her till she recovered.
