Koi Island was once ruled by the late Emperor Nakamura. At the time of his death, rule of the island was passed down to his first-born son, Tadashi. But, there was great unrest as the Emperor's youngest son, Jiro, a hero of war believed that it was in fact he who was entitled to the throne. He, and his supporters, conquered the land to the east. The river, which was once thought to have brought harmony and prosperity was now a harbinger of uncertainty, fear, and fragile security all at once.
