Tropical-Rouge! Precure

Synopsis

Picking off from last episode, the girls examine the damage done to the Grand Ocean Kingdom, during which, they stumble across a room housing seashells containing memories of mermaid who encountered humans before Laura while Butler seals the Marine Ring. The girls meet the real Mermaid Queen, Melusine Muses Mnemosyne, who explains the Witch intends to use her Fool's Casket to gain immortality and make everyone lazy. She also notes that Laura had recovered her memory of her first meeting with Manatsu when she was younger, clarifying that mermaids who meet humans must have their memories of that encounter to be erased via a machine. Butler's Chou Zettai Yaraneeda suddenly strikes again, forcing the girls to transform to engage it again. Stating their resolve to save the world again, the Marine ring appears once more with help from the Legendary Pretty Cure, allowing Laura to salvage the stolen motivation and everyone to defeat the monster with Marine Beat Dynamic. Afterwards, Laura and Manatsu bond once again while Melusine, and the Legendary Pretty Cure recall and discuss the past while the Witch tries to recall her history...
