Technology created in the pursuit of leisure reaches it's peak with the development of the Fractale system, which blurs the line between reality and cyberspace. Personalized avatars called 'Doppels' interact with real people in the physical world, allowing humanity the freedom to go anywhere they like and do anything they like. All of the people's needs are met and catered for by the system. It's a digitally-supported paradise.
One thousand years later, Fractale begins to corrode and systematically shut down. Before it is gone completely, it's keepers, the enigmatic people of The Temple, initiate a plan to reboot Fractale and restore paradise. But a rogue element, a cult of anti-system insurgents that call themselves the Lost Millennium, seize this opportunity to attempt to shut down the system for good, recognising all the hundreds of years of growth and development wasted due to mankind's en masse addiction to Fractale.
One day while returning home from an errand he meets and rescues a girl called Phryne from some LM pursuers. After hiding out with Clain for a night, she vanishes by morning, leaving in his care a brooch which (after cursory examining) releases the seemingly ownerless humanoid Doppel Nessa, a perpectually upbeat ten year old girl around whom the series will primarily revolve, as both The Temple and the Lost Millennium attempt to retrieve both her and Phryne as part of their plans to restore or destroy respectively the Fractale system.

We learn of the world through the eyes of Clain, who was raised within the system but comes to spend enough time in the company of the LM movement to see it from a
It may not be greatest series of all time, but if you like your anime to present to you ideas and leave you thinking, it's fully worth the watch.
Plus the English dub stars Brina Palencia in full-on convincing young boy mode, and the always amazing Luci Christian as Nessa. And Luci is *always* worth the admission price.
