Summary and Preview
Kaguya Haruyama is a young girl who, when about four years old, is found abandoned with no memory of her past. For many years she lives with a Japanese foster family until Idou, a monk loyal to Kura, and Seeu, an emotionless prince, appear in her home. While they fight each other, Gold - Seeu's robot modelled after Kaguya's deceased brother Kagami - brings Kaguya to Telene, a world parallel to Earth, on Seeu's orders. After exploring the world with Kagami, Kaguya encounters Shiina Mol Bamvivrie who calls her the "Girl of Ananai", a girl destined to save only one of the nine parallel worlds from collision. Shiina explains that nine worlds exist: Ancient, the first civilized world that was mysteriously destroyed; Asu, Seeu's disintegrated world; Eden, present day Earth; Telene, a small world allied with Geo; Fifth World, a politically neutral world; Geus, a peaceful world under the control of Geo; Geo, the most powerful of the worlds; Asuraitsu, Geo's rival; and the Ninth World, destroyed before the start of the series. To move from one world to another, hourglasslike devices called "Collapsers" are used to create a bend in the dimensional fabric. Shiina and later Waseda, a student at Tokyo University trapped in the body of a giant rooster, joins Kaguya and Gold in traveling across Telene. After hearing about Seeu's tragic past from Waseda, Kaguya decides to change the fate of the nine worlds by going to Geo to confront Kura, Geo's decadent emperor who ordered Idou to kidnap her. However, Gold brings her to Seeu's floating castle in Asu. Meanwhile, Kura captures and recruits Shiina into his army.
Seeu's castle moves to the Fifth World where Kaguya makes an interplanetary broadcast, announcing that she refuses to choose one world to save and will instead choose a person to help her save most of the worlds and the people. Kura begins to destroy other worlds in order to increase Geo's survival chances. Deciding to use Kaguya as a political figurehead, he sends Shiina to abduct her; however, Kaguya refuses to help him. Angered, Kura divulges that the "Girl of Ananai" legend is a hoax spread around by him and Kagami. After a brief battle with Shiina, Seeu arrives to rescue Kaguya and she realizes that she loves him. Suddenly Gold transforms into a dragon and teleports everyone to the first world; there the sages persuade Idou, Seeu, Kura, and Shiina to combine their powers with Gold to fix the riff in the universe, the cause of the eventual collision between the worlds. The series ends with an epilogue seven years later, with Kaguya explaining the fate of everyone and meeting Seeu and their small son with a picnic basket.
