NieR Automata 'The children of ice'

Hundreds of years ago humanity was faced with an extinction-level event when a deadly virus began to wipe humans out, eventually, they turned to something known as Project Gestalt which was supposed to serve as humanities saving grace by allowing humans to remove their souls from their bodies and thus become immune to the virus, however, there were those who did not think this was the best course of action, namely one family in particular, the Vikters family.

Instead, the parents of this family had begun construction on a number of cryo pods to cryogenically freeze themselves to save their family from the virus without the risk of removing their souls and any issues that may arise from doing so, however by the time they had finished the first two the parents were already infected and it was too late for them and so they had their two children get into the pods and froze them to save their lives before they could be infected too, with their final words being that they loved them.

Now thousands of years later the two siblings step out into a world vastly different to the one they once knew where they will face trials and tribulations at every turn, but as long as they have each other they will prevail, but one must wonder how the androids and machines of this new world will react to the last two humans on Earth.
