Among the four Duchies that represent the Empire of Alliope, where divine beasts dwell, the House of Moonrefe incurred the wrath of a divine beast for certain reasons, and lost everything. To save his crumbling house, Young Duke Edenver performs an ancient summoning ritual, determined to call a creature to take the divine beast’s place. Though he swears with grim resolve that no matter what monster appears, he will subdue it and make it his divine beast. "Piiya!" What emerges is nothing more than a tiny, pitiful baby dragon who hasn’t even shed its eggshell?! And the very first words it utters, once a translation spell is cast "Piiya... pii pi... (Husband... the feed tastes awful...)" Can Edenver really restore his Duchy with Ashil, a baby dragon who suddenly insists on calling him 'husband'?
