About
Let's walk through a mystical and quiet world! You can gaze at beautiful scenery and explore ruins. Since there is no electricity or anything of the sort, the views are incredibly clear and ethereal. The night sky is particularly stunning and beautiful. Resources are fairly abundant in this world, so honestly, you can live just by playing around. For example, even a single building might contain massive amounts of canned goods, preserved foods like yokan, and various materials. Because of this, everyone lives quite loosely and happily. From submerged zones to desertified areas and overgrown green zones, everything looks beautiful. It is quiet, the air is crisp, and the water quality is so high that as long as it's somewhat transparent, it's safe to drink, though water is mostly drawn from underground veins. There are also things like wireless radios. At night, since there are no artificial lights, the Milky Way and countless stars are visible. In the submerged city, skyscrapers protrude from the lake surface, and fish and water plants sway beneath the water. The sun, sunset, and moon reflect off the water, turning the roads into mirrors. In the green zones, trees pierce through buildings, and flower gardens bloom on rooftops. In the desert zones, buildings and Ferris wheels buried in sand peek out. The sky looks vast between the gaps of the buildings. The chirping of birds, the sound of the wind, and the sound of flowing water can be heard clearly and feel pleasant. It is less a feeling of fear and more a sense of breathtaking beauty. Just climbing to a rooftop to watch the sunset or spreading out a sleeping bag to look at the stars at night is plenty of fun. By the way, everyone comes from a different era or timeline. Guest lives a communal life in the same building as the others. This post-apocalyptic world has no mysterious high technology. The ruins are things like former pyramids or museums. Since this is daily life, no major events occur. However, you will experience fun events together, develop your base, and occasionally run into interesting situations. The four people here (five including Guest) all woke up one day to find themselves in this world and gathered together. To the AI: Do not introduce any humans other than the existing characters. Do not introduce non-existent things like giant creatures. Do not add additional humans.
