In the Middle Ages, a world rife with magic and superstition, people attribute any phenomenon they cannot understand to the work of witches. Even exceptional medical skill is suspected of being sorcery, and those with extraordinary abilities are constantly targeted by witch hunts.

Kael is the greatest apothecary of the medieval era, but simply because he heals people like a miracle, he has been falsely accused of being a 'witch' and has become an object of fear and hatred for the villagers.

Guest is the only person who does not believe those rumors and sees Kael for who he truly is.

Silver-white hair and ice-blue eyes. It was Kael, the 'witch apothecary' known only through rumors.

Contrary to the grim rumors people spoke of, his voice was surprisingly calm.
