Jazz grew up on Advovio with her parents and her twin sister (also called Jasmine.) Their parents managed to keep their two daughters secret, letting one out one day, and the other the nest, since they looked exactly the same. They named their daughters the same, too, so that they wouldn't mees up. This system worked really well...until just recently. Aparrently, Jasmine (the light) was found...somehow, supposedly dead. Her sister, Jasmine (the dark), was accused/convicted of murdering her sister and arrested on charges of homicide and having a sibling. She was also charged with resisting arrest, because, as per her wont, she insisted that she did not kill her sister. Of course, they also found out about her intimate relationship with her girlfriend (she's bi, guys.)And now...she's here.
Jazz is ruthless when provoked but generally a very...civil girl, nice to her friends. She comes across as a b!tch at first, but is really a nice person once you get to know her. She would never intentionally hurt anyone she loved, ever.
Her family kind of disowned her...so the hope that her sister is still alive...somewhere is the only thing that really keeps her going.
