The Witch and the Beast Series by Kousuke Satake, 佐竹 幸典

A WITCH'S CURSEGuideau: a feral girl with long fangs and the eyes of a beast. Ashaf: a soft-spoken man with delicate features and a coffin strapped to his back. This ominous pair appears one day in a town that's in thrall to a witch, who has convinced the townsfolk she's their hero. But Ashaf and Guideau know better. They have scores to settle, and they won't hesitate to remove anyone in their way...

After a routine job, Ashaf and Guideau have a run-in with a berserk "undead" -- a deceased human being restored to life through the art of necromancy. Though the city strictly regulates the practice, these aberrant cases have only been growing in number. In his stead, Ashaf recommends his colleague Phanora and her assistant Johan, though the pair is as much a mystery as the one they intend to solve...

A MYSTERIOUS LEGACYGuideau and Ashaf 's next assignment puts them in pursuit of the youthful witch Helga, but they'll have to contend with the illustrious Paladin Corps to secure their target. Helga herself has every intention of keeping her freedom--an aim better served if only her demon sword Ashgan would cooperate. With dark secrets plaguing all sides, just who will triumph in this free-for-all?

THE DEMON SWORDPaladin Corps officer Matt Cugat joins forces with Guideau and Ashaf in one last stand to protect the demon sword Ashgan from falling into the wrong hands--but their efforts are no match for the Executioner's clever ruse. As all bear witness to the ancient weapon's awakening, what sort of terrible calamity awaits? And is there anything that can be done to stop it?

THE WRATHFUL WITCHAn unexpected encounter with Angela, the witch responsible for Guideau’s curse, leaves Guideau in a primal, beast-like state. The regression calls to Ashaf’s mind the time the pair had first met—it was in a village out in the countryside, a place supposedly untouched by magic, but where rumors of a witch began to poison the community…

A HIDDEN WORLD In pursuit of Angela, Guideau and Ashaf venture into the Fall—an immeasurably deep chasm that acts as a portal to other worlds, including the land of vampires, Orlencia Sett. As outsiders, the pair must rely on two envoys from the Order to navigate this unfamiliar territory. However, Guideau and Ashaf soon find themselves ensnared in a self-serving plot orchestrated by one of their companions, a plot that could upset the status quo of the vampire underworld…

Guideau and Ashaf continue their mission in Orlencia Sett alongside Dunward and Oscar, with tensions running high as each party is anxious to achieve their goals. To reach the Queen of the Night, they must first make contact with the Bridge—a mediator among the deeply divided vampire factions, known for his peculiar taste for flesh…

A NEW DAWNDunward, Oscar, and Ashaf finally come face to face with the Queen of the Night. The encounter reopens old wounds for Dunward, and he must make a critical decision if he hopes to have his revenge. Meanwhile, unbeknownst to those in the fray, Guideau and a new weapon are not far behind...
