A girl who gives everything away meets a baby that demands everything from her, and the show uses that collision to ask what selflessness actually costs. The transformation sequences are frame-perfect animation that makes transformation feel like a real power, not just a costume change. This is Pretty Cure for people who notice that helping others can hollow you out if you're not careful, and the baby at the center of the story is the embodiment of that trap. It builds to something genuinely unsettling beneath the glitter and frills. The pacing sags in the middle run, but the emotional architecture never breaks.

Mana Aida is a middle schooler and student council president who is always eager to help others. On a school orientation trip to Clover Tower, invaders from the Trump Kingdom turn people's selfish desires into giant monsters, and one of them tries to twist Mana's own heart. After meeting the warrior Cure Sword and her fairy companions, Mana partners with the fairy Sharuru and transforms into Cure Heart, the Pretty Cure of Love. Her friends Rikka and Alice are soon pulled in as Cure Diamond and Cure Rosetta, and a mysterious baby enters their lives as the four Cures fight to protect the love in everyone's hearts. The result is a magical girl fantasy about friends battling side by side.
