A mysterious girl named Eureka arrives at the home of Renton Thurston looking for the Amita Drive, necessary for the proper functioning of her LFO, the Nirvash, throwing his life into chaos.

As the military descends, Renton delivers his late father's invention to Eureka and unleashes Seven Swell, which is her craft's hidden power.

A young teen who surfs the skies with his ref board grabs the chance of a lifetime when he is invited to join the pirate organisation Gekkostate.

The Council of Sages discusses the Nirvash's immense display of power and how it is connected to Adrock Thurston. Meanwhile, Renton joins Gekkostate to get closer to Eureka, only to find himself at the bottom of the organisation.

When a shopping trip with fellow Gekkostate members Talho and Hilda turns ugly, it's up to Renton to pilot an LFO solo for the first time in order to keep everyone form getting into too much trouble.

Eureka's kids pull a series of pranks on Renton, dead-set on keeping anyone from getting too close to the woman they call Mama. Meanwhile, Renton goes out on a dangerous mission without authorisation from the rest of Gekkostate.
