Ép. 50: Mia et Hye In vainquent Kintarou pour restaurer la symphonia reconnaissante et sauver le monde.

Asechi Kintarou turns the prism stars happiness into sadness and captures Mia and Hye In. He tells the girls that the only way to be the best is to forget about friendship and the future, and plans to complete the grateful symphonia by his own design and cover the world in darkness. But Mia fights back telling him he's wrong. As Kintarou closes the gate to the grateful symphonia, Mia throws Hye In through it before it is sealed, thereby causing her to become the new Symphonia Goddess. But the symphonia tiara does not appear and Hye In is left in empty space wondering if this is really what she wants. Realising that being the best is meaningless without her friend, Hye In encourages Mia along with the people of the world. Mia gains the power to open the gate to the grateful symphonia and both girls receive the tiara and become the center, completing the grateful symphonia and bringing everyone's dreams of the future to light. Kintarou reconciles with Kyouko and Kei and everyone returns to normal. (Source: Wikipedia)
