In 2045, two children born on the moon and three kids from Earth try to survive after an accident on their space station leaves them stranded.

The story takes place in the year 2045 in outer space, where AI, the internet and social networking sites are widespread. A massive accident occurs on a newly opened Japanese commercial space station, and a group of children are left behind. With no hope of rescue from adults, their lifeline is a barely surviving narrowband, a social network, a free application of low-intelligence AI and a drone controlled by a AR-based mobile device called "Smart". Will they be able to use these tools to survive the crisis?
