This is a list of characters
in the anime and manga series Eureka Seven
, with accompanying biographical information from the series. Those listed are those who are in some way relevant to the primary plot. They are broken down into three main categories (the three "factions" in the series): Gekkostate, a group of renegades formed from a defunct special forces group; the U.F. Force, the United Federation of Predgio Towers' main military force in the series; and the various civilians that live across the planet.
Yuko Sanpei (Japanese), Johnny Yong Bosch (English)
(レントン・サーストン, Renton Sāsuton
?) is the male protagonist, the son of the late military hero Adroc Thurston and co-pilot (later become pilot) of the Nirvash typeZERO. He is an outgoing and emotional person possessing strong ideals and compassion, yet is naive and tends to jump into matters before understanding what is going on. Before joining Gekkostate, he lived with his grandfather Axel Thurston in Bellforest, attending school and learning to be a mechanic in Axel's shop. He was heavily influenced by his sister Diane Thurston and believes that he will see her again one day. Though somewhat of a celebrity due to his relation to Adroc Thurston, Renton feels uncomfortable about being his son. His surname is recognized everywhere he travels, and he constantly feels as if he lives in his father's shadow. Renton believes Adroc was a poor father who abandoned his family for his research.
After the Nirvash accidentally crashes into Renton's room next to Axel's garage, Renton meets Eureka and falls in love with her at first sight. He joins Gekkostate to follow Holland, his idol, and to be with Eureka. Renton's unusual link with the Nirvash and responsibility over his father's Amita drive are also factors in his decision. His transition to life in Gekkostate proves difficult, as he is subject to many pranks from crew members (especially Eureka's adopted children). He eventually comes to learn of the origin of Gekkostate and the atrocities that Holland, Eureka and the others are atoning for. Renton stays with Gekkostate to train, and in time his skill as an LFO pilot develops to rival Eureka's. This development creates a rift with Eureka, as she initially does not return his feelings for her. His love for Eureka is not secret; everyone on board the Gekko interferes in his love life. The crew members constantly want to know his progress and cheer him on. His relationship with both the Nirvash and Eureka develops into a deep emotional and mental link that is noticed by Mischa.
Renton has a special link with the Nirvash along with Eureka. Usually, both he and Eureka are necessary to activate the Amita drive, awakening the Nirvash and allowing access to the power responsible for the Seven Swell phenomenon. Specifically, when Renton and Eureka achieve emotional agreement and wish for something, the Nirvash reciprocates with the power of the Amita drive. If their feelings are in disconnect, the Amita drive cannot activate. However, there are some occasions where Eureka is present yet unconscious, and Renton alone convinces the Nirvash to awaken. Renton summons the powers of Amita drive several times throughout the series. The first instance was triggered by an overwhelming need to protect Eureka during his delivery of the Amita drive to the Nirvash and the Gekkostate, resulting in the second-ever occurrence of the Seven Swell phenomenon (the first being Adroc's disastrous experiment with Eureka).
