History
Annalise Gremory was born as the second child of Zeoticus and Venelana Gremory. She was presented to the Bael Elders to see if she had inherited the Power of Destruction only to be turned away when it was discovered that she didn't. Due to this, Annalise grew up shunned by her mother's side of the family and was seen as the Black Sheep. Sirzechs often tried to stand up for her but he could not be there all the time. One day, the heir of House Dantalion pushed her over the edge and she awoke her father's blood, the Power of Sight. The young heir was placed under a horrific illusion that tore apart his mind and left him brain-dead. Word spread to the Gremory Elders who had been watching her since the Bael turned her away. The elders began grooming her to wield the Power of Sight. Zeoticus took it upon himself to train her.

With the outbreak of the Devil Civil War, Annalise fought as Sirzech's first lieutenant. She discovered his secret affair with Grayfia Lucifuge and kept it a secret. Eventually, at the end of the war, Annalise was offered the position of Beelzebub but declined, opting to travel the world with her best friend, Alfred Belial.

During her travels, she heard of the tale from various myths of the Emerald Dragon. The rumored third Dragon God. She and Alfred searched for the Emerald Dragon only to fail. She eventually stopped and became the Head of the Department of Education before retiring with her sister's move to Kuoh and her daughter's birth.

Appearance
Annalise is a beautiful woman in her early twenties with blue eyes and long red hair that went down her waist and was styled with a single strand of her bangs braided, as well as the sides of her hair being pulled back and held together by a small basic clip. She had a very well developed and curvaceous figure, sporting a bust size slightly larger than Rias's. Her blue eyes twinkled in amusement as she stared down at her. The woman wore a white collared blouse, black jacket, plaid skirt, black thigh-high socks, and penny loafers.

Personality
Annalise is shown to have a playful personality. She loves to tease Rias on her relationship with Issei and laughs whenever she gets flustered and responds to her comments. Rias mentions that she is a loving sister often reading her bedtime stories when she was a young child. This causes her to have a rivalry with Sirzechs for Rias's affection to which Rias admits that Annalise is her favorite sibling. Annalise is also a loving mother to Mira.
