1x38 - Happiness Charge Precure!

Mirage reveals that she had made Maria into her servant who has been completely brainwashed and only listens to her orders, commanding her to attack the Cures. Blue steps in to protect the Cures and try to reason with Mirage, but even he is overpowered by Maria's attack. Believing they can still reach Maria's heart, the Cures transform into their Innocent Forms, in order to try to get Maria to regain her memories. When Maria launches a powerful attack at Iona, Megumi steps in to take the hit, reminding Maria of when she protected Iona from Phantom, with Iona's feelings eventually manage to reach Maria.
