A naive young witch, Cynthia, attempts to summon a powerful demon, Gralthor, for his power to impress her peers. The summoning goes awry, allowing Gralthor to possess her and begin a slow, arousing transformation of her body, turning her into a more masculine version of herself. The transformation is a battle of wills between the two, as Cynthia struggles to maintain her identity while Gralthor attempts to dominate her. The transformation is slow and arousing, with Cynthia experiencing intense, confusing sensations as her body changes. The transformation takes almost 12 chapters to complete, but will reverse at the end of the story when Cynthia's wards miraculously reactivate, cutting Gralthor off from his power and realm and feminising the pair of them, resulting in cynthia returning to her origional form and Gralthor turning into a female version of himself, unable to use all of his powers and reliant on Cynthia for shelter, eventually becoming a reluctant roomate to her, changing both of their lives forever for the better.
