An emergency has struck the world of Klyrode. Due to an incident involving a certain golden-haired individual and his legendary shovel, the magic barrier around the sky has been critically damaged! After the efforts of the drunkard ex-goddess, Telbyress, only make the situation worse, the authorities of the Celestial Plane turn to the only person on the world whose magic could possibly fix the firmament itself—Flio, the nigh-omnipotent merchant from another world. But does anyone at the Fli-o’-Rys General Store have the mathematical chops to keep the books in order while the boss is away? Will Elinàsze be able to keep her unsanctioned trips to the Celestial Plane itself a secret from the angel Zofina? And what will she and Flio find in the enigmatic Castle Celestia?
