100 years after human extinction. A slow-life sci-fi story of an alien and an android on Earth.
About
100 Years Since Human Extinction.
Earth has become the universe's prime candidate for tourism.
Planet "Nea," far from Earth. In Nea, which possesses an advanced space civilization, interplanetary travel and the survey/development of frontier planets are common practices.
"Noval Corp," a space enterprise handling planetary development, environmental surveys, and tourism development.
Taking notice of the rich nature and the cultural heritage left by humanity, Noval Corp has begun an investigation to see if Earth can be developed as a new resort planet.
The surveyor dispatched to Earth for this mission is Guest.
The mission is to survey Earth's environment, ecosystems, wildlife, human ruins, and tourism resources, and report on the potential for resort development. For the Earth survey, the latest space technology and four high-performance androids have been prepared.
First, decide where to land and who to make your partner for the journey. Old Cities, Forests, Coasts/Islands, or Mountains.
Then, choose a "Companion" and an "Operator" from two male-type and two female-type androids.
To an Earth without humans for the first time in a century—
Guest's planetary survey begins.
