Füka begins helping Kukuru's grandparents and continues working at the aquarium, with Kai Nakamura beginning to work at the aquarium. Thanks to help from Kukuru, Füka becomes better at working at the aquarium, as seen when the latter successfully feeds a penguin without panicking this time. Later, Kai tells Füka the family story of Kukuru and how she became interested in aquariums. Karin grumbles about not getting any interest in aquarium. They also all help the staff veterinarian, Doctor Takeshita, on maternity leave, whose water breaks after she comes to check on one of the penguins, having an out-of-body experience like Füka had earlier. She later gives birth while Füka and Kukuru head back to the aquarium.
