The year is 2685 A.D. Technology has developed to the point where humans can control even the weather! Virtual reality tech is also highly advanced, allowing people to fully immerse themselves in virtual worlds offering unprecedented experiences.

~A post-apocalyptic world where humanity is nearly extinct. How would the survivors think and act in such an environment?~

The protagonist decides to participate in Navigatore, a new VR project produced by a popular internet program. There she meets with Harunashi Mika and decides to partner up with him. When the two awaken and step outside, they find themselves in a barren, deserted landscape... one seemingly far too realistic to be the product of virtual reality.

As they get their bearings, they hear the voice of the program's announcer:

"A man and a woman placed in extreme conditions... can they survive? How will they survive? The audience is dying to find out! We're hoping for plenty of human drama and maybe a bit of romance!"
"The guided part of the tour is over. Your life in the wasteland begins now! We shall await the conclusion of your story with bated breath!"
