Go! Princess Precure

Synopsis

Minami's family invites the gang aboard their cruise ship, where Minami meets a girl named Asuka Kitakaze who works as a vet at the local aquarium. Asuka shows Minami and the others around as she checks up on the animals, suggesting Minami is suited for this line of work. Later at a party, Minami learns that Asuka is a marine biology expert who has been approached about joining the Kaido group, but declined in order to remain free and keep following her own dream of understanding the ocean. Just then, Stop and Freeze target Asuka to create a Penguin Zetsuborg, with Minami stepping in to protect the ship from harm. After the Cures defeat the Zetsuborg, Asuka encourages Minami to keep pursuing her dream.
