Eureka Seven
Renton is a teenager trapped working as a mechanic in a backwater town. He dreams of joining up with a daredevil group of pilots known as Gekkostate and following in his father's heroic footsteps.
When a mysterious beauty named Eureka shows up asking for a tune-up, Renton soon finds himself drawn into a high-flying mecha dogfight that makes him a target of the military. When the dust settles on the spectacular battle, Renton is invited to join Gekkostate, but he soon discovers that even a dream come true has a dark side.
