Gyokuren

With Karen, Suiren and Hakuren, one of a group of four handmaidens to Seto Kamiki Jurai, often referred to by fans as the Seto Scouts.

The eldest of the group. Her nickname is "The Ghost," because she can keep others from sensing her presence. Note this is not because it's faint to begin with, but because she can naturally erase it. Occasionally she's even snuck up on Lady Seto herself. Gyokuren is one cause of the eerie legends about what happens around the Tenju("Heaven's Tree" - the site of the Juraian royal palace) both day and night.
