Trans girl Embra spent much of her life trying to live as herself. When she is rescued by Shantae, the half-genie hero of Scuttle Town, she learns she was blessed by a Guardian Genie who loved her and adopted her when she was young.

The blessing takes full effect, and Embra becomes a half-genie herself! The body she always wanted, with unusual powers given to her by a Genie of Light: Shade Magic, a set of darkness powers formed from the genies' Light Magic. As she unwinds her complicated past, she discovers a danger that threatens the very structure of the world... She must make allies and discover the full strength of her powers to prevent an incarnation of hate from ripping the world (and beyond) asunder!
