Set after Ending E - A new challenge awaits 9S and 2B as the two androids attempt in vain to recover what was lost. Along the way, they'll discover what's left in the world after all sense of purpose has been stripped from it. And in so doing, they may perhaps discover what it means to finally be free.

On a mission to discover the cause of several recent disappearances, 2B and 9S come across a dying machine, and a dark stain from the past comes back.

2B wants to feel something, before 9S's system reboots and resets. In the end, it's these emotions that keep her going. Again and again. Maybe it's selfish because she knows 9S won't remember but, still, it's a practiced ritual. Various M rated oneshots. End Game Spoilers.
