Synopsis
Post-apocalyptic world after global flood; Keel navigates politics as factions clash over rebuilding society.
In a post-apocalyptic world where the catastrophic "Hammer of Eden" event flooded 90% of Earth's land and claimed billions of lives, humanity struggles to rebuild. Fourteen years after the disaster, the New United Nations has formed to establish peace among the scattered survivors. The story follows Keel, a young man living in Yabitsu—a town that has managed to prosper thanks to energy from a nuclear generator salvaged from the catastrophe. His life becomes intertwined with global politics when his relative Aoi rises to a prominent position within the New United Nations, advocating for a new world order where nations can transcend their historical differences. As tensions rise between competing visions for humanity's future, various factions emerge with conflicting ideas about how to establish lasting peace in this devastated world. Military forces, political leaders, and ordinary citizens all grapple with the question of what kind of society should rise from the ashes of the old world. Set against the backdrop of environmental collapse and human resilience, this series explores themes of power, survival, and the price of peace in a world forever changed by disaster.
The catastrophe, "Hammer of Eden," resulted in the loss of six billion lives and the flooding of 90% of the land. The New United Nations were formed to pursue peace on the ruined lands 14 years later. Keel is a boy living in a town called Yabitsu, an area which prospered due to the energy from the nuclear generator brought by the catastrophe. His next kin, Aoi, is the secretary general of the New United Nations. She views the catastrophe as an opportunity to create a new world in which nations can help one another overcome differences in races and religions. However, her efforts to realize that vision fail because of the unwillingness of the nations to change. Gould, a military officer, feels that the only way to make an order is through the military. Using Ulysses, a nuclear submarine, along with his crew, including Keel's brother Tean, Gould carries out a coup to declare war against the New United Nations in his attack on Yabitsu.
