Among the four great duchies of the 'Aliope Empire,' where divine beasts exist, is the House of Moonlefe, which lost its divine beast after incurring its wrath for reasons unknown. The young duke, 'Edenvere,' in a desperate attempt to save his declining family, performs a summoning for an ancient creature to take its place… He was grimly determined to subjugate whatever monster appeared and establish it as their new divine beast, but the creature that actually answered his summons was— "Pp-ii!" A small, insignificant baby dragon that hadn't even shed the eggshell from its head?! What's more, the very first words it spoke to him after he cast a translation spell were: "Ppii… Pi-yapi… (Husband… Asil doesn't taste good…)" Can Edenvere truly save his duchy by making this baby dragon 'Asil,' who calls him 'husband' right from the start, into their divine beast?
