"Eureka Seven: Gravity Boys & Lifting Girl" is a manga series that serves as a prequel to the anime "Eureka Seven," exploring the origins of key characters and events that shape the main storyline. The narrative is set in a world where humanity coexists with sentient beings known as Coralians and relies on advanced technology, particularly mecha called LFOs (Light Finding Operations), for both daily life and conflict.

The story centers on Dominic Sorel, a young soldier in the military organization known as the United Federation, and Anemone, a genetically engineered pilot designed to control the powerful LFO known as the Nirvash Type-ZERO.

Anemone's role as a test subject and her connection to the Nirvash highlight the ethical dilemmas surrounding human experimentation and the dehumanization of individuals for strategic gain.

As the story progresses, Dominic and Anemone are drawn into a larger conspiracy involving the Federation's secretive projects and the true nature of the Coralians. Their journey reveals the complexities of loyalty, sacrifice, and the search for identity in a world where the lines between humanity and technology are increasingly blurred.
