In 2034, metallic monsters called the Tekki appeared and dismantled most of human civilization in their wake. The simultaneous failure of all metal-based technology accelerated the collapse. Humanity survived only in the narrow spaces between Tekki activity. A thousand years passed. A single hero finally struck a decisive blow against the core of the Tekki threat, and the battle for survival ended. What comes next is harder to define. The story is set in Kanto — a nation of eight hundred empowered individuals that resembles a distant echo of Japan, a place whose entire culture was built around the fight to exist. The fight is over. Nobody knows what to do with that. A young man from the distant past is excavated from cold-sleep hibernation, confused and without memory but carrying the accumulated knowledge of ancient civilizations. In exchange for food, clothing, and shelter, he agrees to bring culture to a world that has only ever known war. This is a story about coffee shops and paper currency and what it means to lead, about a girl who was nobody and found her footing, and about the life and death of a hero. More than anything, it is a confession.
