About

As Yuko starts helping out Pretty Cures from around the world, the girls are approached by Aloalo, the fairy partner of Hawaii's Pretty Cure team, Alo~ha Pretty Cure, who have been struggling against the Phantom Empire's commanders, Madam Momere. The girls travel to Hawaii, which has been completely frozen over, to meet up with twin sisters Ohana and Olina, a.k.a. Cure Sunset and Cure Wave respectively, who are struggling to get along with each other due to their different methods of fighting. After Yuko uses her lunches to help lighten the mood between them, the sisters decide to put aside their squabbles and work together with the HappinessCharge Cures for the sake of saving Hawaii. After the HappinessCharge defeat one of Madam Momere's Saiarks, Ohana and Olina realise the importance of their sisterly bond and work together to defeat the other Saiark, returning Hawaii back to normal.
