Tide-Line Blue

In the aftermath of a global catastrophe known as the "Hammer of Eden," which submerged 90% of the world's landmass and claimed billions of lives, humanity struggles to rebuild. Fourteen years later, the New United Nations has emerged as a fragile governing body attempting to unite the scattered survivors. Keel, a young resident of Yabitsu—a town that has managed to prosper thanks to energy from a salvaged nuclear generator—lives a quiet life in this new world. His guardian, Aoi, holds a prominent position within the New United Nations, working tirelessly toward her vision of a unified humanity that transcends old divisions of race and religion. However, tensions simmer beneath the surface as different factions debate the best path forward for civilization. As various groups with conflicting ideologies emerge—including those who believe security can only be achieved through military might—the delicate balance of this recovering world faces new challenges. The story follows Keel and those around him as they navigate the complexities of rebuilding society while confronting the ghosts of humanity's past and the uncertain future that lies ahead.
