Renton Thurston, a bored fourteen-year-old fixing lifting boards in his grandfather's garage, gets pulled out of his routine when a girl named Eureka crashes an enormous mecha called the Nirvash typeZERO through the roof asking for repairs. Smitten on sight, Renton talks his way aboard her ship, the Gekkostate, and starts training as her mechanic and copilot alongside veterans like Holland Novak and Talho Yuuki. This manga retells the TV series' story of Renton leaving home to join Eureka's crew, condensed into six volumes.
