Xia survived the accident in which her older sister Nyah thought that she had perished. However, due to the great trauma of this, the accident caused Xia to lose her memory and become an amnesiac. She therefore had no memory of her older sister and of her family.
She was then raised by a mysterious man. This individual cared for her like she was his own daughter. He had lost his wife earlier in a storm, and so she was his only family left. He was a classical piano player, and Xia picked up her love of music from him.
Eventually, Xia learned about her true heritage. She then decided to come to Japan and reunite with her sister.
Coming to Japan, Xia met up with her long-lost sister. The normally composed Nyah was in total shock over her appearance.
She is often nice and gentle to others, but when angered can become quite fearsome.
