Asechi Kintarou uses prism stars to capture Mia and Hye In, claiming friendship hinders becoming the best. He attempts to seal the grateful symphonia, but Mia pushes Hye In through the closing gate, making her the new Symphonia Goddess. Though Hye In lacks a tiara and questions her choice, she realizes being the best is meaningless without friends. She encourages Mia and the world, granting Mia the power to reopen the gate. Both girls receive the tiara, becoming the center of the grateful symphonia and illuminating everyone's future dreams. Kintarou reconciles with Kyouko and Kei, and normalcy is restored.
