Lady Phenex looks exactly like her daughter, Ravel, in her early twenties with the same blonde hair and blue eyes, with the only exception of her hair being done up very high with ornate hair decorations.
Lady Phenex has a very kind and gentle personality. She also has concerns about Ravel's well-being, being apparently aware of her daughter's feelings for Issei, even subtly teasing that they should marry, much to Ravel's embarassment.
Not much is known about Lady Phenex nor about her family, other than at one point prior to the series, she married into the Phenex Clan and eventually gave birth to four children: three sons and a daughter. Also that, while a King, Lady Phenex has mostly retired from the Rating Games.
Lady Phenex makes her official appearance in Volume 10, thanking the Occult Research Club for taking Ravel in and asking Issei and Rias to take care of her daughter. She also tells Issei that her daughter is currently a "free" Bishop, trading her from her son prior. Before leaving, she encourages her daughter to deepen her relationship with Issei and work hard to preserve their family's pride.
In Volume 22, Lady Phenex appeared at Issei's High-Class Devil promotion ceremony along with Riser where she meets up with Issei to trade his bishop piece for Ravel to enter his Peerage.
