Deltora Quest (デルトラ・クエスト, Derutora Kuesuto?) is a Japanese anime series based on the series of childrens books of the same name, written by Australian author Emily Rodda. It was announced by Rodda herself at Sydney's Book Council of Australia Conference and at an ABC Kids convention.
Emily Rodda conceived of the Deltora series as a classical quest featuring a continuing storyline told over several books. She purposely modelled the structure of the series on the structure of a video game, after noting how engaged her own children were with video games.
The series was produced by Oriental Light and Magic and SKY Perfect Well Think. Rodda was approached with many film offers, but this studio promised not to change the story, although the main character(Lief)'s hair has been changed from black to blonde. It aired its first episode on January 6, 2007 in Japan.
It was directed by Mitsuru Hongō (Spirit of Wonder, Outlaw Star), designed by Hiroyuki Nishimura and Junya Ishigaki, and written by Oketani Arawa, Reiko Yoshida and Natsuko Takahashi. The music was composed by Kō Ōtani.
