Based on the Victorian-goth otome girl's game. Hannah inherited her grandfather’s ability to make “elemental dolls,” but he forbade her to do that after she made her first doll, her maid Emily. After he died however, Hannah discovered a strange male “elemental doll” called Will in the basement of her grandfather’s workshop. Who made Will and for what purpose? Why is he calling her “master” and are there others like him? These are only a few of the mysteries Hannah has to solve.
