Based on watching the first episode :]
Set in a futuristic world where people live in a very convenient place where about everything can be done with machine. A curious boy finds himself helping out a prisoner of some sort, which could probably get him in a lot of trouble but nonetheless.. curiosity defeats him. If I have to guess, this anime will be about the friendship between this escapee and this curious boy. This anime is probably going to be about conspiracy within no.6 and such. Kinda makes me think of Fractale.
