After her mother passes away, Ann decides to become a Silver Sugar Master like her mother—a highly regarded occupation in the country of Highland, where very few masters of the craft exist. Ann leaves for the town of Lewiston, where the royal family holds a sugar sculpture festival. To become a Silver Sugar Master, she has to win the top spot and receive a royal medal.
In this world, humans treat fairies as slaves and take one of their wings to control them. Ann reluctantly buys a fairy named Shall to be a bodyguard on her way to Lewiston. Ann is torn between setting Shall free, but needing a bodyguard on the dangerous roads to the festival.
Reincarnated as a sentient weapon with memories of his past life, but not his name, a magical sword saves a young beastgirl from a life of slavery. Fran, the cat-eared girl, becomes his wielder, and wants only to grow stronger, while the sword wants to know why he is here. Together, the strange duo's journey has only just begun!
