Hitoshi becomes the judge of a beach beauty contest. The winner gets to go to Guam with him. The girls, along with Cynthia McDougal compete in various events. Finally, it's down to Saati and Cynthia. Cynthia wins and Saati is disappointed. Cynthia decides not to go to Guam, and everyone is happy. Cynthia shows up at Hitoshi's high school. It seems that she's decided to spend some time at a Japanese school. Cynthia says she came to learn about Japanese guys and that Hitoshi is her "type". The male class mates are envious of Hitoshi. She sends Hitoshi an e-mail asking him to meet her alone. They go out on a date, and Hitoshi leaves Saati behind. Saati gets jealous. Saati disguises herself, and follows them on the date. At the end of the date Cythina confronts Saati. Cynthia tells Saati that she is serious about Hitoshi. It's time for the high school festival, and each class must put on an event. Cythina decides that her class should put on a play she wrote called "The Little Mermaid". She casts Saati as the mermaid and Hitoshi as the prince, while Cynthia plays a human girl. They rehearse the play, and the other students are very impressed.
Cynthia tells Saati that she will leave the last act unwritten, and let Hitoshi decide whether he chooses the mermaid(Saati) or Cynthia. The one he doesn't choose has to give him up. Saati accepts the challenge. When they perform the play for the class, Saati and Cynthia compete for Hitoshi's attention by appealing to his perverted longings. In the end, not realizing the stakes, Hitoshi chooses Cynthia and Saati runs off. Saati begins removing her memory and her powers. When Cynthia tells Hitoshi what really happened, Hitoshi is furious, and runs off to find her. Hitoshi finds Saati throwing her memory disks off a bridge, into a river. Hitoshi Jumps into the river to save the disks. It looks like he may drown. Cynthia, Twenty and Forty come. Cynthia ties a rope to herself and anchors it to the ground, she dives in and catches Hitoshi's hand. But, Hitoshi won't grab her with his other hand, in which he holds the disks. Finally Saati uses a program option to save the day. Cynthia agrees that Hitoshi should be with Saati. Twenty notices that Saati's hand was bleeding, an unusual occurrence for an A.I. program.
