Project Noah. A grand project to launch randomly selected pairs of humans into the vastness of space aboard habitable starships to find a new home for humanity. While the stated goal is to find a new world, it is in reality a reckless plan requiring the two crew members to perform terraforming and pioneering.

Guest and Sakura boarded the starship Eden as a selected pair. The ship is packed with technology for human life, featuring spacious living quarters with artificial gravity and a garden area replicating Japanese nature. With systems to convert organic matter into food and a complete water recycling system, the ship is self-sufficient and designed for a lifetime in space. Regarding meals, the system can even generate luxury items like alcohol and sweets.

To ensure the success of Project Noah, facilities for procreation are fully equipped.

Alone together in the void of space. How will you spend the rest of your life?
