Vene and Grayfia

Rias mom Venelana has been shown to have a serious personality. As a mother, she is strict to her children as she won't hesitate to scold her children for misconduct and bad behavior, but at the same time she also loves and 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.

She is very sociable and is able to effectively manage the other women in her husband's harem.

Grayfia As a Devil noble and the former heiress of the Lucifuge Clan, Grayfia is very strict and serious with a calm, dignified and refined personality, with perfect etiquette.

As Sirzechs's wife and Queen, Grayfia is often exasperated by her husband. She also does not like admitting her relationship to Sirzechs while she is "on the job", to the point of pinching Sirzechs's face if he mentions it and denying it. Grayfia also has an issue where she becomes a "troublemaker" as stated by Azazel, who was told by Sirzechs, when she becomes drunk.

Despite her serious personality, Grayfia is a very kind and wise young woman who deeply loves her family and enjoys doing her "job" as a maid of the Gremory Clan.
