Eureka Seven, known in Japan as Psalms of Planets Eureka Seven (Japanese: 交響詩篇エウレカセブン, Hepburn: Kōkyōshihen Eureka Sebun; lit. "Symphonic Psalms Eureka Seven"), is a Japanese anime television series created and produced by Bones. The series was directed by Tomoki Kyoda, with series composition by Dai Satō, character designs by Kenichi Yoshida and music by Naoki Satō. Eureka Seven tells the story of Renton Thurston and the outlaw group Gekkostate, his relationship with the enigmatic mecha pilot Eureka, and the mystery of the Coralians. The fifty-episode series aired on MBS between April 2005 and April 2006.

The series spawned six manga adaptations, a light novel, three video games and a feature-length anime film which was released in April 2009. A sequel anime series, titled Eureka Seven AO, aired 24 episodes between April and November 2012. A manga version of Eureka Seven AO was serialized in Monthly Shōnen Ace between January 2012 and October 2013. Eureka Seven was well received by critics and earned several awards at numerous award shows in Japan, most notably the 2006 Tokyo International Anime Fair.

The series focuses on Renton Thurston, the fourteen-year-old son of Adrock Thurston, a military researcher who died saving the world. He lives what he considers a boring life with his grandfather in a boring town. He loves lifting, a sport similar to surfing but with trapar, a substance abundant throughout the air, as the medium. He dreams of joining the renegade group Gekkostate, led by his idol Holland Novak, a legendary lifter.

An opportunity to do so literally falls into his lap when a large mechanical robot, called the Nirvash type ZERO, and Eureka, its pilot and a member of Gekkostate, crash into Renton's room. Renton's grandfather orders him to deliver a special part to the Nirvash called the "Amita Drive", which releases the immense power dormant within the type ZERO called the "Seven Swell Phenomenon". Afterwards, Renton is invited to join Gekkostate, where he quickly discovers that the behind-the-scenes life of Gekkostate is hardly as glamorous or as interesting as printed in the glossy pages of their magazine, ray=out. Only one thing makes it all worthwhile for him: the presence of Eureka, the mysterious pilot of the Nirvash. Renton, Eureka, and the Gekkostate embark on an adventure that will shape their future as well as the world's.

The series was made by Bones and co-produced by Bandai Entertainment. Bandai Entertainment provided the title and handled the creative aspects of the series. Bandai had originally proposed a mecha anime series to the animation studio Bones. The studio had initially rejected it, but later reversed its position because it had already planned to create an anime using mecha designs by Shoji Kawamori. With the appointment of director Tomoki Kyoda and writer Dai Satō, Bandai's proposal was more or less scrapped and the staff began work on their own series that would become Eureka Seven.

While conceptualizing Eureka Seven, Kyoda "wanted something that reflected the music and the subculture of his generation—and a love story." As such the show contains several references from music of the 1980s and the 1990s, and almost all of the show's episodes are named after real songs, composed by both Japanese and foreign artists.

The director wished to design the series as one that would at first focus on the personal elements and conflicts of the characters, then subsequently move the framework into a broader scale and perspective. The series' two halves each have their own very clear focus that reflects this design choice.

With the premise of the surfer robots in mind, Satō interviewed several real-life surfers and came to the conclusion that they are close to nature. From this perception, he envisioned the environmental thematic as central point of the story. He said "I thought it might be an effective message for children, especially in Japan. It's pretty veiled. I didn't want to be preachy."
