The Era of Memory: the Dawn and Dusk Line at Midnight

The end of the world, a dying era, a world on the verge of destruction. In Doomsday 4026, the world's energy is in crisis. There are frequent wars, countless disasters, and the end of the world that mortals imagine is coming. All civilizations in the world have been destroyed, leaving only a land that is still struggling in the apocalypse - Wattlang. Despite this, Baita, the chief scientific researcher of the human civilization organization "Pareopol", discovered a new era called the world of memory - a world of synesthetic consciousness composed entirely of memories. He took this opportunity to launch the "Eden Project" in an attempt to transfer human civilization from the present world to the world of memory. In order to save his sister Kaixi who is suffering from amnesia disease, Kai, the memory hunter, went to the world of memory to do underground business of buying and selling memory. By chance, he joined Paleopol, the organization where Baita is located. However, is all this really a coincidence? Unreasonable heresies, bizarre deaths, plans covered by glory, Kain, who has experienced a series of encounters and partings in the world of memory, will wield a sword related to civilization when morning and dusk meet.
