Manatsu and her friends hike while the Witch and Butler discuss Laura's lack of motivation. The Tropical Club notices Laura is missing and finds her in the library reading The Little Mermaid. Manatsu encourages Laura and hides her mermaid identity from her mother. That night, Laura explores the human world. The next day, a Zenzen Yaraneeda attacks the port. The girls engage the enemy, but the monster and Chongire capture Laura. Defeated, the four girls discuss their situation until aquarium director Mafune Hirabayashi encourages them.
