After successfully protecting the Kingdom of Merinard from the Principality of Diieharte and the Kingdom of Tigris, it's time for Kousuke to return home to the capital and enjoy a hard-earned rest. Well, that was the plan, anyway. When Serafeeta starts putting the moves on Kousuke, it sparks tension between him and Sylphy's two older sisters, Ifriita and Aqual. And while Kosuke's hands are full trying to keep all three of these beautiful women happy, another bomb drops--someone's pregnant! Can Kousuke catch a break?!
