Mary is a sweet Vampire race girl with tall and slender stature. She has long attractive red hair and golden eyes.

Mary dressed all in black as she wears an outfit consisting of a black shirt, a red ruffle tie, black pants with red and gold accents, black gloves, calf high boots, and a black cape with red and gold accents that covers the shoulders and back, also wearing a wide-brimmed hat like a pirate's hat with red and white feathers.

As a vampire hunter, she bring a black cross sword.

Personality
Mary is a kind person, unlike vampires in general, she doesn't think of Human as cattle, she doesn't even hesitate to always help someone when she's in trouble. She is a very loyal person to her master, Elisabeth as she is unable to go against her orders or to kill her. In fact, she does everything to protect her master from bad people, including Crimson.

After Elizabeth went on a rampage, Mary dedicated her life to tracking her down and killing any vampires that do harm to humans.

Tragedy of a Dream
In the past, Mary was once a follower of the "Blood Queen", Elisabeth, which she become her loyal servant and her second in command. As a subordinate, she changed shifts to bring food to Elizabeth's room. However a tragedy occurred when it was Crimson's turn. Mary drinks the corpse's blood so she can control the out-of-control Elizabeth. Then she chased after her and the others who had left the territory. After three days, she managed to find Elizabeth, but it was already night when it was all over.

A remorseful and tearful Elizabeth orders Mary to throw her ashes into the sea. But, Elizabeth's sword path missed a vital organ, so she fell asleep and one day she was able to wake up again. Mary could do neither, nor go against her master's orders, nor kill her, so she decided to hide in the immortal coffin and protect him no matter what.

After stopping her master insatiable genocidal rampage, Mary made it her mission to slay any rogue vampires that dared threatened humanity and other species until she becomes a Ancient Vampire Hunter. One thousand years later, Crimson stole Elizabeth's body from Mary, she couldn't protect her due to her powerlessness and to her rejection of blood.

Elisabeth
Mary is devoted to the Blood Queen, Elisabeth as Mary chooses to imprison her instead of killing her master or allowing her to suffer because of her vampire nature, to the point that she even had to hide the Blood Queen's body in a coffin and vowed to protect her forever from Crimson after the previous Red Moon incident because she did not have the heart to do the deed, even though she could not go against her master's will. However, her decision is already backfires when Crimson manages to overpower her and took Elizabeth.

Beta
When Beta accidentally made a remark about the Vampire Progenitors being similar to demons, Mary is enraged at the comparison as she condemning it as blasphemy for the Progenitors.
