Description
Noélle Bor, codenamed Mistress, is a human nun associated with the Saint Mercedes Convent of the Catholic Church. She is employed by the Ministry of Holy Affairs and serves in its special operations division, the Papal State Affairs Special Operations Section, known as AX. In the anime series, she remains an active member of AX, while in the original light novels, she had retired from the agency by 3060 AD but continued to work as an undercover agent based in Barcelona. She has long black hair and black eyes, and her appearance reflects her role as a religious sister and field operative.

Her personality is warm, kind-hearted, and approachable. She possesses a gentle demeanor and shows genuine care for those around her, especially her colleagues. She is also shown to have a light-hearted side, as seen when she tries to enjoy sightseeing during a mission with Abel Nightroad. Despite her gentle nature, she is a capable and dedicated agent who takes her responsibilities seriously.

Noélle Bor's motivations are rooted in her faith and her commitment to protecting others. She serves the Vatican and the Church out of a sense of duty, and she is willing to risk her life to carry out her missions and help those in need. Her actions are driven by compassion and a desire to do good, rather than personal ambition.

In the story, Noélle Bor plays a supporting role within the AX team. She is deployed alongside Abel Nightroad to investigate the collapse of the National Palace in Barcelona, a mission assigned by Cardinal Caterina Sforza. During this investigation, she and Abel discover the plot involving the Silent Noise weapon, a destructive device created by the Rosenkreuz Orden. Noélle is killed when the weapon is activated and levels the city of Barcelona. Her death has a profound impact on Abel, leaving him despondent and struggling with guilt and loss for a significant period afterward. Her sacrifice also provides crucial information that helps the AX team later understand and confront the threat.

Her key relationship is with Abel Nightroad. She harbors romantic feelings for him and eventually confesses her love. Abel receives her confession gracefully but gently declines, telling her that he is blessed to have her as a special friend. This unrequited affection adds a layer of personal tragedy to her story. She also works under Cardinal Caterina Sforza and interacts with other members of the AX team, though these relationships are less developed.

Noélle Bor's notable abilities are psychic in nature. She possesses the power to read minds and what appears to be a form of clairvoyance. She can also track people by location, an ability visually represented by her eyes glowing and allowing her to see illuminated footprints in a room. These skills make her valuable for intelligence gathering and investigation. Her codename, Mistress, reflects her mastery of these abilities.

Her character development is limited due to her early death in the narrative. She appears as a capable and loyal agent, and her death serves as a catalyst for Abel's emotional arc, highlighting the dangers and costs of the conflict with the Rosenkreuz Orden.
