The series begins in Japan, in the year 2030. Yun Arikawa and Haberu Katou, two workers at the "do-it-all" Otaki Factory, are hired to investigate strange power fluctuations at an abandoned mansion. They find a hidden radio that's picking up a repeating broadcast, which Yun identifies as an old Indian folk song, and trace it to a radio-monitoring station called Misakioku. Meanwhile, graduate student Mei Kamino is brought in to investigate a strange alarm at Misakioku, and discovers that the alarm is connected to the same broadcast. Mei is later contacted online by a copy of Naratake, a popular AI created by Yun, which she renames "Pelops II." Yun and Haberu's boss, eccentric scientist Gorou Ootaki, theorizes that Misakioku and the broadcast are part of SETI and are connected to alien activity. Gorou publicly unveils his newest creation, a giant robot called Jet Jaguar, at a local festival, but the event is thrown into chaos when a pterosaur-like monster called Rodan suddenly appears. Meanwhile, it's revealed that the secret basement of Misakioku houses the skeleton of another giant creature. (Source: Wikipedia)
