イーリス亭小夜曲

"Iris-tei Serenade" is set in a medieval fantasy land. For seven years, the two most powerful countries - the Empire of Aimar and the Kingdom of Langbard - have been at war with each other. In order to secure the victory, the people of Aimar turned to Imar, their hero and guardian angel. Imar's mission is to infiltrate the Langbard kingdom. However, once he arrives there and stays at the inn run by three young and lovely sisters, his mind turns into a direction quite different from war and politics...
