Johan is a supporting character who appears alongside his partner, Phanora Kristoffel, as members of the Order of Magical Resonance. He is introduced when the series shifts its focus to a case involving illegal necromancy, which falls outside the primary protagonists’ area of expertise. At first glance, Johan appears to be a composed and professional assistant, often seen wearing a black eye patch over his left eye. He works in the field as the physical counterpart to Phanora, who is the more cerebral of the two.

The most defining aspect of Johan’s character is his true nature. He is not an ordinary human but an undead familiar, a living corpse that was resurrected by Phanora. The practice of necromancy in this world is a highly regulated and legal process, but it carries significant weight; the dead who are brought back forgo an afterlife and eventually face a final, permanent end. Despite his status, Johan maintains a personality and appearance that are almost indistinguishable from a living person, a testament to Phanora’s skill as a necromancer.

Johan’s personality is marked by an unwavering loyalty and a calm acceptance of his situation. Though he is treated almost like a servant and often takes on the more dangerous tasks, he never complains and seems unbothered by his subordinate role. In one instance, when another character suggests that Phanora does not treat him well, Johan responds that he has no complaints and is content with their arrangement. His dynamic with Phanora is a relaxed and comfortable one, built on mutual professionalism and composure, contrasting with the more volatile relationship between the series’ main duo. There are hints of a deeper, potentially romantic connection in their past, given that Phanora chose to resurrect him, but their present interactions are characterized by a quiet and understated care for one another.

In the story, Johan and Phanora serve as a narrative device to explore the complex legal and ethical dimensions of magic in their world. While the primary protagonists are hunters focused on destroying witches, Johan and Phanora are specialists who manage the bureaucratic and societal issues caused by rogue necromancy. Their role is to track down necromancers who break the law by creating uncontrolled undead, or strays, that terrorize the populace. In this capacity, Johan acts as the muscle, engaging in direct combat while Phanora analyzes the situation. This is notably illustrated when he fights for his life against a horde of zombies while his partner calmly discusses the case in the foreground. In a confrontation with a renegade necromancer, Johan is seemingly killed and his body taken, a situation that ultimately reveals the true extent of his unique nature as an undead servant bound to Phanora. His development is subtle, existing primarily to highlight the themes of love, death, and unnatural resurrection, while also providing a compelling parallel to the series’ main protagonists by presenting a functional partnership between a witch and her beast.
