On March 31, the members of SEES, except for Masto, speculate that Makoto's death was related to him using his life force to defeat Nyx. The school year has ended, and the dormitory they stayed at is to be closed down soon. But before their last dinner party, the SEES members discover that they are trapped in their dorm, and that the day March 31st is repeating itself. Later, a large door-like hole opens in the floor of the dorm, and SEES is attacked by Metis, an anti-shadow weapon similar to Aigis. In the midst of fighting Metis to protect her friends, Aigis' Persona, Athena, transforms into Orpheus, the original Persona that Makoto once used. She also gains the same power he had, the power of the Wild Card. They learn from the mysterious Metis, that with Makoto's death a mystery labyrinth called the Sands of Time was formed by something relating to Makoto's death and will change what the team believes to be their true answer to go on to their future.
