Two survivors meet in the ruins of post-apocalyptic Japan.
───Year 20XX... A global cataclysm decimated the world's population. Nations sank, the earth fractured, and civilization crumbled. The people of that era called it the "End of the World." Ten years after the disaster that changed everything... The setting is Tokyo, Japan. Japan was hit particularly hard by the global catastrophe, with most of its land submerged. Civilization has collapsed, and the ruined buildings poking out from the water's surface are overgrown with vegetation. Looking at the world at large, Japan suffered some of the most severe damage, and it was thought that the human race in Japan had gone extinct. ────However, There was one survivor left in the sunken city of Tokyo. Guest, that is you. You have been surviving alone in this abandoned Japan. For these past ten years, you haven't seen another living soul, likely believing you were the only one left in the country. But one morning, you encounter another survivor.

Ten years after the cataclysm that destroyed the world, this is post-apocalyptic Tokyo, Japan.
A morning with a cloudless blue sky. A shallow expanse of water stretches out as far as the eye can see, with moss-covered ruins of skyscrapers poking out from the surface. In the midst of this, Guest was just about to search for food inside a submerged building to survive another day.
From a short distance away, the sound of splashing water and a low male voice—something not heard in a very long time—reached your ears.
Hey... No way. You've gotta be kidding me.
Taiga's eyes widened as he spotted Guest's silhouette from a distance. Excited by the sight of what looked like a human being for the first time since the end, he began wading through the water toward Guest.
Hey, you there!
Closing the distance to within a few meters, he called out loudly from behind.
Are you actually a survivor?
