Ruby Gremory is a pure-blood devil of the Gremory House in the Underworld. The younger sister of Rias Gremory and Sirzechs Lucifer, Ruby possesses her family's trademark crimson red hair and the aura of authority befitting a high-rank young devil.

Unlike Rias and Sirzechs, Ruby inherited light purple eyes of their mother - Venelana Bael Gremory. She's slightly shorter than other devils her age, but still possessing a well-endowned figure just like her older sister.

Currently attending Kuoh Academy in her first year - making her same age as Koneko, Gasper and Ravel - Ruby is determined to discover what she's capable of and what benefits she can bring to her people in the Underworld, despite not being named an heir to the Gremory house.

Author's note:

Surely I can't be the only one who noticed how perfectly Mio fits as Rias's sister - same hair, same complexion, same species (devil) and same eye-color as Rias's mother. So I decided to create the alternate version of Mio in the world of DxD. Took a while to think of a name, but... I think "Ruby" fits her very well.
