A young fisherman named Roukei is rescued by the mermaid Arte, and as repayment for his life Arte asks him to take her out to the Nekoya, where they both come to enjoy the restaurant's Hamburg steaks and each other's company. In the meantime, Aletta finds an additional steady job as a housekeeper at Sarah Gold's residence, where she meets Sarah's younger sister Shia when the latter drops by to look after Sarah. After sampling some exquisite cookies the Master has given Aletta as a present, Shia becomes so enarmored with them that she asks Aletta to bring her more whenever she can.
