Cure Answer and the others have their transformations dissolved by the sheer power of Eclipse Shadow. As Cure Eclair's secrets and Luluka's true intentions are revealed, Anna and Mikuru transform into Precures again and extend their hands to Kurea.

With nowhere to go, Luluka spends her days at Pâtisserie ChuChu. While she's there, a customer's lost item containing a Makoto Jewel is stolen. Anna and the others deduce that the culprit must be among three customers on the terrace and prepare to question them, but Luluka intervenes.
