This anime is really great!! The feelings after watching it almost can't be told!
I've seen 5 episodes out of 6. and i have no patience to wait until last episode is airing.
The story is really outstanding. robots would be used in the future, and with upgrading and updating a software they become used everywhere and the thing is what is the guarantee that one day robots wont stop being just an artificial intellingence but something that could make decisions itself without anyone's order, moreover something that would have feelings??
