Bido: The Girl of the Key

Entrusted with a mysterious box and given no explanation, a girl named Bido sets out on a journey through a world governed by the laws of the sun and moon. There, a power known as Mirkin bends those very rules, while the Empire proclaims it to be the will of the gods. As unfamiliar companions, an imperial holy knight, and the secretive Silver Moon Order close in around her, Bido begins to realize that the burden she carries is neither ordinary nor accidental.
