Believe Yourself. Super Cute Cure Coral!

Manatsu heads out on a weekend trip around Aozora City with a couple of her classmates including Sango. The group meets at the city's shopping mall where Manatsu is fascinated by the merchandise sold and Sango gives her purchased ice cream to a younger girl. The group then heads off to the aquarium where Sango is separated from them while trying to return a lost wallet. Sango then tries to search for her friends only to cross paths with Laura. The next day, Sango confides in Manatsu that she does not like standing out among others due to an incident back in kindergarten. Upon hearing her out, Laura encourages Sango to believe in her "cute". Later that day, Chongire summons a Yaraneeda to attack a park, forcing Manatsu to head off to transform and confront the monster. When Cure Summer and Laura get overpowered by the foe, Sango, who followed Manatsu to the battle, finally plucks up her courage to believe in her own choices. As a result, the second Tropical Pact opens, granting her the power to transform into Cure Coral who, with Laura and Cure Summer's help, defeats the Yaraneeda. After the battle, Manatsu and Sango become closer friends and resolve to do their best, even as Pretty Cures.
