Once a year in the snowy town of Fueya, diamond dust fills the air on the Night of the Fairies — and miracles are said to happen. On one such night, Crow Yamada appears on the rooftop of the patisserie Folkroll with no memory of how he got there. The shop is in danger of being sold to a corporation while the head baker is hospitalized, but his granddaughter Meru and her friend Kori refuse to let that happen. Crow decides to become a great patissier to help save it. Will he ever remember who he is, and why he was on that rooftop in the first place?
