Manatsu Natsuumi is a 13-year-old first-year middle school student who moved to Aozora City from Minamino Island (南乃島) to be with her mother. Upon her arrival on the mainland, she begins her new life there and her first semester in middle school. But one day, she meets Laura, a mermaid from a mystical place called Grand Ocean, the land of mermaids. She has been searching for the legendary warriors of the Grand Ocean who can fight against the Witch of Delays, an entity from the bottom of the ocean that attacked the nation and deprived its inhabitants of their Motivation Power. Although Laura is searching for the legendary warriors because the Mermaid Queen tasked her with doing so, she is doing it out of her selfish desire to be queen one day. But when one of the witch's minions attacks Aozora City, Manatsu is blessed with the powers of the sea that allows her to become Cure Summer, one of the legendary warriors foretold in Grand Ocean's legends.

Manatsu is later joined by Sango Suzumura (Cure Coral), Minori Ichinose (Cure Papaya), Asuka Takizawa (Cure Flamingo) and Laura (Cure La Mer). They form the Tropical-Rouge Pretty Cure team to fend off against the forces of the Witch of Delays and restore the Grand Ocean to its former splendor.

Grand Ocean (グランオーシャン, Guran Ōshan) is the home of Laura and Kururun, which is ruled by the Mermaid Queen.

The Witches of Procrastination (あとまわしの魔女たち, Ato mawashi no majo-tachi) are the main villains of the series, and are the group made up by the Witch of Delays and her marine subjects, who seek to end the motivation of the mermaids of the Great Ocean and the humans by absorbing Motivation Power from them.

Minions of the Witch of Delays under Butler's leadership, each based on a marine species. They can throw orbs at objects to create Yaraneedas/Zenzen Yaraneedas/Zettai Yaraneedas/Super Zettai Yaraneedas that steal peoples' Motivation Power, leaving them unmotivated and lethargic.
