In the depths of the Serpentback Cave, a brimmed cap casts its murky shadow upon Qifrey and his apprentices. The brimmed cap's dark magic has transformed Euini into a wild beast, and Coco, Tetia, and a critically injured Qifrey find themselves surrounded by the venomous stares of the cursed Romonons. In the face of doom, these witches must once again find a path to safety using their wits and their unique qualities, but will that be enough as they battle against a powerful new enemy who doesn't play by the rules?
