Maria Wong

A singer, famous worldwide for her beautiful voice, from China. She came to Japan to perform a concert. She committed suicide because her stepmother always acted as the ringleader in her life, but only because she wanted to use Maria to achieve money and fame. Her stepmother then went to Muraki, who raised Maria back from the dead, but with one exception; she would need to consume human blood for survival, revealing her identity as the vampire in the Nagasaki File arc of the story.
