is the son of the late military hero Adroc Thurston and co-pilot of the Nirvash typeZERO. He has been in love with Eureka the other pilot of the Nirvash ever since he first saw her. He is a very outgoing and emotional person possessing strong ideals and compassion yet is naive and tends to jump into matters before understanding what's 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, being the son of a savior, Renton feels uncomfortable being the son of Adroc Thurston. His surname is recognized everywhere he travels, and he constantly feels as if he lives in his father's shadow. Renton believed Adroc was a poor father and abandoned his family for his research.
