It is the 23rd century, and the human race inhabits the moon. The earth has been a dead planet since the great calamity, a global eco-disaster triggered by the crash of the colossal space station Freeport. The survivors on the moon founded the Lunar Republic of Eden, a utopian city which guarantees its citizens lives of peace and stability, but at a price: life in Eden is closely monitored and controlled by the powerful regulatory body known as The Guidance Council. Fifteen-year-old Takeru doesn't know the first thing about Eden politics, but has a nagging feeling that things -just ain't right.- He vents his frustrations by racing LTVS -Lunar Terrain Vehicles- with his buddies and generally wasting time. The Guidance Council keeps a close watch on him, as they do all citizens, but are aware that such teenage folly rarely leads to any real problems. However, when Takeru is sent on a community service outing to atone for his mischievous behavior, he stumbles upon something that could get him into real trouble, since it may actually be important: a photograph, recent and unaltered, of a girl on Earth.

During routine maintenance on the lunar surface, Takeru finds a strange capsule containing a single photograph. Captivated by the enigmatic girl in the photo, he scours the city in vain for clues to her identity. In desperation, Takeru and friends turn to old man Alan - and are shocked by what he reveals. In search of the truth, Takeru and Kazuma escape Eden, but are soon pursued by mysterious robots. Will they head back to safety - or speed past the point of no return?

Takeru and Biz speed through space in the emergency escape craft launched without Guidance Council approval. Kazuma, who was meant to fly with Takeru, was left behind to face the wrath of a very perturbed Guidance Council. When Takeru and Biz land on Earth they find it to be a little closer to what Eden had always told them it was: A great lifeless expanse of desert and devastation.

After a 200,000-mile quest to Earth, Takeru somehow finds Ao - the girl in the photograph - living in a desolate Florida village among the ruins of the NASA space program. But he soon discovers his search for love has just begun... As he tries to fit in as an alien on his own home planet, he learns of a mysterious legend known only as "FREEDOM." And the Chapter of Earth continues...

With the fate of mankind riding on his shoulders, Takeru vows to return to Eden. And after revealing her childhood memories of a space flight gone horribly - and fatally - wrong, Ao demands to go with him. But can their makeshift rocket, scrapped together from an antiquated Apollo program, make the journey? As the series speeds towards its dramatic climax, it's a voyage sure to end in destiny - or disaster.

A single column of smoke trails across the blue sky. It is the new moon rocket, inspired by the Earth girl Ao's determination to preserve her father's legacy. Two years in the making, the rocket teaches the moon boys Takeru, Biz and Ao's entire village to once again look to the skies and dream.
