Marina and Souma both went on to attend the same university and are enjoying their daily lives. One day, Marina experiences interference from another dimension. This disrupts the chain of causality, resulting in the appearance of many fallen Marinas from another dimensions. The only way to return them to normal is for Souma to satisfy the unfulfilled desires of the fallen Marinas.
