The Masked Holy Knight is an enigmatic Holy Knight directly serving under Great Holy Knight Hendricksen.

Appearance
The Masked Holy Knight wears a regal Holy Knight armor with a long dress, wearing unique helmet resembling hands enclosing on her face with one visor. She wields an unusually large claw-like staff.

Personality
The Masked Holy Knight is a calm, brooding and cunning woman who served Hendricksen with much if not greater loyalty than Helbram. She has extreme hatred of pigs after encountering Hawk in front of her as she snapped and teleported the pig to a faraway place. The Holy Knight also show great resentment towards the Seven Deadly Sins for reasons unknown as she stated to have loved them once before and encouraged Gilthunder to finish him off. Despite that she has some sense of honor as she allowed Elizabeth's wish for her sister Margaret to be released from her cell, although mocked the latter's cowardly nature and allowed the king and his daughter to have a brief family moment before proceeding with the ritual.

Kingdom Infiltration arc
When the Seven Deadly Sins discuss in Boar Hat as to why the Holy Knights are focused on targeting Elizabeth, the Mask Holy Knight reveals herself by telling them that the princess of Liones is the last remaining key of the Coffin of Eternal Darkness to release the Demon Clan before teleporting herself with Elizabeth, and unknowingly Hawk to the kingdom. Her actions greatly angered Meliodas as he and his fellow Sins Ban and Gowther immediately launched a risky rescue attempt to save Elizabeth in face of the entire Liones' Holy Knights. Later when Elizabeth regains consciousness in a cell, the Masked Holy Knight welcomed her back to the kingdom before teleporting away. At some time after discovering Elizabeth's escape, she teleported before Hendricksen and reported the situation while noticing King Arthur Pendragon of Camelot and his cloaked friend being surrounded by the Great Holy Knight and his subordinates. After receiving orders to recapture the princess and relocate her to a place where the Sins can't reach her, the Masked Holy Knight bade farewell to the young king before teleporting away again.

Shortly after, the Masked Holy Knight found Elizabeth near Margaret's cell, informing her that the First Princess allowed herself to be imprisoned due to her cowardice when she was accused by Elizabeth and attempted to take her only to be pushed back by Hawk. Seeing a talking pig in front of her, she expressed disgust and teleported Hawk to the Horn of Cernunnos telling him to disappear, which knocked Elizabeth unconscious. The Masked Holy Knight then allows Margaret to leave her cell granting her captive's wish of her sister's freedom, if she have the courage to do so. She then contacted Hendricksen that she recaptured Elizabeth and was given orders to keep the princess away from the Sins as possible. She asked permission to aid Hendricksen but the latter refused, then she gave in and informed him that she'll be sending her cute little knight to aid her superior in battle against Meliodas.

Taking the princess to the king's heavily guarded chambers, she allowed a brief father-daughter reunion as Elizabeth and her father before proceeding with the ritual while observing the battle as she noticed Gilthunder seemingly overpowers Meliodas and telepathically compells him to kill the Seven Deadly Sins she once loved. Then suddenly Threader, captain of the Dawn Roar, appeared before the doors of the king's room having killed several Holy Knights demanding an audience with the king. Threader forcing his way to the King door, but was protected by Perfect Cube while her father begged Threader to stop. The Unnamed Holy Knight went to see Meliodas battle against Gilthunder which surprised her as Meliodas was overpowering Gilthunder and when the Masked Woman said Meliodas name, Elizabeth grew happy to know Meliodas came for her. The Masked Woman told Elizabeth not to get too happy as Meliodas will be defeated soon, but Elizabeth told her that Meliodas will not loose. After the battle gotten much more intense, the Masked Woman went and help Gilthunder and Hendricksen, leaving Elizabeth and King Liones alone for the moment. As the battle rage on, Masked Holy Knight appear and help Hendricksen and Gilthunder in their battle against Meliodas.
