"Psalms of Planets Eureka Seven New Order" is a manga series that expands on the universe of the original "Eureka Seven" anime. The story is set in a world where humanity coexists with sentient beings known as Coralians, who inhabit a mysterious substance called Scub Coral. The narrative centers on Renton Thurston, a young mechanic, and Eureka, a enigmatic girl with a deep connection to the Coralians. Together, they pilot the LFO (Light Finding Operation) mecha known as the Nirvash, which plays a pivotal role in the unfolding events.

The plot begins with Renton joining the renegade group Gekkostate, led by Holland Novak, as they navigate a world rife with political and environmental turmoil. The Coralians, initially perceived as a threat, become central to the story as their true nature and purpose are revealed. The series explores themes of coexistence, identity, and the consequences of human actions on the environment. Renton and Eureka's relationship evolves as they uncover the secrets of the Scub Coral and its connection to the planet's past.

Key characters include Renton, whose journey from a naive teenager to a determined hero drives much of the narrative; Eureka, whose dual nature as both human and Coralian creates tension and complexity; Holland, whose leadership and personal struggles add depth to the group dynamics; and Dewey Novak, Holland's brother and a central antagonist whose ambitions threaten the fragile balance between humans and Coralians. The series also introduces new characters and expands on the lore of the "Eureka Seven" universe, providing additional context and backstory.

The manga delves into the conflicts between various factions, including the military organization known as the United Federation, which seeks to control the Scub Coral for its own purposes. The narrative builds toward a climactic confrontation that challenges the characters' beliefs and forces them to confront the consequences of their choices. Through its intricate plot and character development, "Psalms of Planets Eureka Seven New Order" offers a compelling exploration of its richly imagined world and the relationships that define it.
