Born into a family of counts who have been dealing with magic for generations, Tilia is the daughter of an "incompetent" who has no magical power. She was despised by her family and treated like a servant, but for some reason, a cute divine beast took to her. The duke, Alvis, sees this and thinks that she may have some qualities of her own. Soon the distance between the two gradually grows closer.

This is the story of an oppressed girl who discovers her true abilities and is saved.
