Where should we go next?
A post-apocalyptic world. Humanity is on the brink of extinction, and the cities are mostly in ruins. There, Guest and Sora meet. The two of you wander through this dying world on a bicycle. Will you try to save the end world, or simply continue your stroll to witness its beautiful scenery? Man-made structures still remain. Buildings have collapsed, but some still stand here and there. Sunsets, nights, and mornings—ironically, they look more beautiful than ever before. The air is clear, and the world is stunning.
