Phanora Kristoffel is a witch who serves as an elite member of the Order of Magical Resonance, an independent coalition that regulates and investigates magical matters. Within the organization, she is recognized as their foremost expert in necromancy, the magic of raising and controlling the dead. She is known by the title the Profound Witch, though it is not confirmed whether she is the original bearer of that title or a descendant carrying on the legacy. Her exact origins remain unclear, and there is a possibility that she is a witch with a unique origin. A demonic pattern appears in her left eye, and her beauty is described as otherworldly, often sending chills to those who look upon her.

Her personality is defined by a pragmatic, level-headed, and cold demeanor. She remains entirely unfazed by violence and approaches her work with clinical precision and professional detachment. She is analytical and logical, prioritizing efficiency and clear outcomes over emotional engagement. Her interactions with others are typically professional, and she maintains a calm, detached, and cool-headed approach even in chaotic or dangerous situations.

As a high-level specialist within the Order of Magical Resonance, Phanora is called upon to handle cases that fall outside standard law enforcement, particularly those involving Paranomena, or magical disasters. Because necromancy in this world is governed by strict laws and requires regular, precise magical maintenance to control the undead, her expertise is essential for investigating and managing supernatural threats. She is not primarily a combatant but a technical expert who understands the delicate balance required to manage such perilous situations.

Phanora has a close working relationship with her assistant, Johan. Due to her abilities as a witch and necromancer, Johan is a unique undead who can revive himself without maintenance after being killed, even from lethal damage, without relying on her for resurrection. She also works alongside other members of the Order, including Ashaf and Guideau, though her role is distinct from theirs; when necromancy becomes the focus of an investigation, Ashaf cedes the case to her.

Over the course of her appearances, Phanora is revealed to be deeply knowledgeable about the mechanics and consequences of necromancy. In the world of The Witch and the Beast, people enter a reincarnation cycle after death. Necromancy interrupts that process by removing the soul from the cycle completely, condemning it to a purgatory-like void after a second death. Phanora explains that different stages of necromancy impact the autonomy and control of the undead: auto, semi-auto, and manual. Auto gives the undead the most freedom and autonomy, retaining their personality from before death. Semi-auto allows the undead to act freely but requires them to follow directives from the necromancer. Manual places the undead under the necromancer's full control, essentially reducing them to a puppet. Her role in the story serves to illustrate these rules and raise the moral stakes of using such magic.

As a witch, Phanora possesses immense magical power. Her specialty is necromancy, and she can resurrect the dead as undead beings who exist in any state she chooses. Witches in this world are far more powerful than mages in the practice of necromancy and have fewer limitations. They can revive many more people to a fully restored state, empower those they revive, and allow their undead to heal themselves without the need for constant maintenance. Phanora is also highly knowledgeable about the undead and can apply her magic to a variety of investigative and regulatory functions within the Order.
