|“||Nice to meet you, I’m Rias’ mother, Venelana Gremory. Please treat me well from now on, Hyoudou Issei-kun.||”|
Venelana Gremory (née Bael) is the current Lady of the Gremory Clan. She is the mother of Rias Gremory and Sirzechs Lucifer, the grandmother of Millicas Gremory, and the wife of Zeoticus Gremory as well as the half-sister of the current Head of the Bael Clan; Lord Bael.
Venelana looks very much like her daughter with shorter flaxen hair and violet eyes much like the natural born members of the Bael Clan in the anime. Due to her devil lineage, she appears around the same age as her daughter and her son who appears to be in his early to mid twenties.
Venelana has been shown to have a serious personality being strict to her children but at the same time cares deeply for them. She can seamlessly switch her demeanor from that of a proper, young noble lady to that of the head Lady of the Gremory Family. Venelana can also strike fear at others when she's angered, such as her husband, Zeoticus.
Venelana is quite the intelligent woman when it comes to the business world, as she has got a talent in finding hidden gems that have not yet been properly evaluated at its true price, due to having good connections. She was able to create a huge business out of rare crops that only people who live in the countryside knows or crafts that natives makes, and she was able to make them popular in the city of the Gremory territory.
Venelana is the eldest daughter of the House of Bael that is famous for their Powers of Destruction. However, due to Venelana being the daughter of the second mistress, she did not have the right to inherit the clan. She was known as the Brunette Ruin Princess (an alias which would later be passed to her daughter) before her marriage and was stated to be the strongest woman from the House of Bael of all time. She eventually married the current head of the House of Gremory and gave birth to two children: Sirzechs and Rias, both of whom inherited her Powers of Destruction.
