海的女儿

Plot
　　Neri—the title character—is a young girl with an affinity for water, super-human strength, the ability to swim long distances, and super-human lung capacity. She lives alone on an otherwise deserted island. Early in the first season, Neri befriends two Australian boys: Jason and Brett Bates. This friendship is at first a highly-guarded secret due to Neri's fear of other humans. The Bates brothers live in an elaborate underwater research and environmental protection facility called ORCA, located near Port Douglas, Queensland. At the beginning of the series, they move to ORCA in order for their mother, Dr Dianne Bates, to study whale song. A significant portion of the series takes place on ORCA itself, and looks at the activities of its inhabitants, many of whom are school-aged children, just as Jason and Brett.
　　As the series progresses, it is explained that Neri came to Earth on a spaceship with her father when she was young, though his death soon after leaves Neri to fend for herself. Prior to meeting Jason and Brett, Neri's only friend was a humpback whale (called jali in Neri's native tongue), whom she names "Charley", and with whom she can communicate. Later in the series, Neri's curiosity leads her to explore ORCA, while Dr Bates' study of Charley's whale song helps her identify Neri as the intended recipient of that song. Eventually, Dr Bates and her assistant, Dr Winston Seth, become embroiled in Jason and Brett's effort to keep Neri a secret, while also performing numerous tests on Neri to understand how she's able to communicate with whales.
　　At the same time that the Bates learn about Neri, a rival research organization, the UBRI Corporation, are introduced. Headed by Dr Hellegren, UBRI have learned that a spacecraft landed somewhere in the vicinity of ORCA, and begin their own search for any personnel that may have survived. Simultaneously, they work on other projects which threaten the natural ecology of the ocean around ORCA. Eventually, they put in play an effort to build the so-called "ORCA City", an elaborate underwater construction that will likely eradicate much of the natural life on the seabed. In response, Dr Bates' mission changes over the course of the series from cetologist to environmental protectionist. This role becomes more prominent beginning with the third season, when UBRI representatives establish themselves onboard ORCA. Accordingly, the series shifts to a more serious tone in its later seasons.
　　As Neri gradually discovers more of her island and ORCA, she also begins to understand her greater purpose. This self-awakening is particularly enhanced by encounters with others of her kind. In the second season, she discovers her sister, Mera, and the two are given the opportunity to return to their home planet. Mera avails herself of this option, but Neri stays, feeling that she must discover what her father was trying to do on Earth. In the third season, she gains entry into the downed spacecraft that originally brought her to Earth. There, she finds another of her people in suspended animation. The new character, Kal, proves to be the son of the pilot of the vessel, and helps her tap into the ship's memory core. She finds the ship's log, which explains that her father was trying to find a substance that would revitalize Earth's oceans. She then dedicates her life to her father's cause, giving her a genuine sense of purpose that she had perhaps lacked earlier in the series. Kal grows jealous of the strong bond between Neri and Jason Bates, and begins hating Neri's friends on ORCA. As protest, Kal leaves the island, and cannot be found by Neri and her ORCA mates, and had been capture
