On February 29th, children under the age of 14 are said to have their wishes granted on a day known as Melly Day. In a world where all individuals can use magical powers, Hiasen has the high-risk ability to manipulate things from reality in his dreams... but all he really wants is to see his father again, who happens to be a wanted criminal. When his wish is granted on Melly Day, the world as he knows it changes forever and he gets tangled up in a series of murder and concealment.
