Synopsis Setting The world consists of eight continents where magic saturates the environment, influencing both nature and civilization. Magical disasters are collectively called "Paranomena", while spellcasting involves inscribing runes, known as "Lettering", either in the air or on prepared surfaces. The Global Holy Church regulates magic from its seat on the First Continent, with technological advancement decreasing in more distant lands. However, the eighth continent is able to develop its own unique brand of magic technology, allowing it and the seventh continent to have prosperous societies. Between them lies the Fall, a seventeen-tiered abyss created by the Origin Witches, each level containing its own isolated world known only to the powerful elites.

The Church's Paladin Corps handles major magical threats, while their Executioners branch ruthlessly hunts all witches. Three holy women lead the Church: the Healer, the Defender, and the Seer, who periodically awakens to prophesize future turning points called the Great Flow. Witches descend from the seventeen Origin Witches, inheriting vast power marked by Ultoma sigils when casting spells. Though outwardly human, they live two centuries without aging. Humans who master magic become mages, with the five strongest recognized as Archmages. Magic interferes with machinery unless purified, and practitioners can be neutralized through pressure points or finger injuries. Other beings like the nearly immortal vampires are capable of challenging mages.

The Order of Magical Resonance, an independent coalition of magic-wielders and supernatural beings, frequently opposes the Church's methods but maintains an uneasy truce to prevent outright war.

Plot The story follows Ashaf, a tall, soft-spoken agent of the Order of Magical Resonance, and his unruly partner, Guideau, whose soul resides in a female body, yet her true form is that of a powerful, masked "beast", contained within a coffin strapped to Ashaf's back. They are tasked by the Order of Magical Resonance to solve cases involving magic, especially those concerning witches. As they go about their missions, they travel the world seeking a particular infamous witch, Angela Anne Huell, who casts a curse on Guideau and is the only Origin witch still alive.

Due to unknown reasons, Forbidden Instruments, dark magical tools that grant the wielders immense power at the cost of blood sacrifices, are being spread around the world. At the core of it, Angela and a coven of witches and mages are prophesized to become a "great enemy" to society, causing the Order and the Holy Church to scramble to stop them.

Characters Main characters

A mysterious "beast", Guideau is trapped in a female form due to a witch's curse, but her real form is a powerful masked man with a pitch-black right arm and is the "natural enemy" of witches. She reluctantly works with the Order of Magical Resonance to find the witch who hexed her and break the curse. Guideau can temporarily release the curse by kissing a witch, but it only works once per witch. Although she inhabits a witch's body, Guideau cannot use magic, but has superhuman abilities, such as enhanced strength and heightened senses. Guideau is foul-mouthed, aggressive, egocentric, and ignorant about many aspects of the world. Her tendency towards violence and her burning hatred for witches tends to cloud her judgement, but she can be rational and is learning more self-control. While single-minded in her goal and apathetic to everything else, Guideau has slowly developed a trusting and somewhat abrasive partnership with Ashaf.

A proud and confident first-class mage of the Order of Magical Resonance, Ashaf is a tall, gentlemanly, chain-smoking man. He is partnered with Guideau, whom he first met three years earlier, and carries the coffin with her real body strapped to his back. Knowledgeable and skilled in many fields of magic, Ashaf primarily fights using magical barriers and summoning animal familiars, particularly crows. Mature and intelligent, Ashaf is perceptive of others and handles the numerous dangers of his job with a cautious, cool-headed approach. Ashaf is generally caring, sociable, and has a playful sense of humor, but can be pragmatic, dubious, and rather enigmatic in his actions. Despite playfully antagonizing her at times, Ashaf keeps Guideau in line and takes responsibility for her in various ways, including teaching her about the world. While Guideau views Ashaf neutrally as a partner, Ashaf has more ambiguous feelings for Guideau, admitting to caring deeply about her, but hints at a more complex reason to his relationship with her.

Known as the "Profound Witch", Phanora specializes in necromancy and is one of the most powerful members of the Order.

A tall, dark-haired man with a patch over his left eye, Johan is Phanora's personal assistant and her partner in the Order. As a "special" undead, Johan possesses an immortal body capable of regenerating without Phanora's magic, as well as superhuman strength, and is a skilled knife-wielding combatant. Laid-back and good-humored, Johan faithfully serves Phanora and handles the "physical labor" aspect of their job.
