Every thousand years, the Dark Reign rises and pushes forth to destroy all humanity, but those of the Shoreline Nation have dedicated their lives to defending the world from this recurring threat, using the magic within themselves and their bonds between each other to stave off these vicious foes. It is here that Tasuku trains, expecting the next rise to come generations later, but now as signs of the Dark Reign are uncovered with their nation still unprepared, Tasuku finds himself thrust into a battle that will determine the fate of the world. Can two people find hope for the future with an outlook so bleak? Is it possible for friendship to turn into intimacy on the eve of humanity's destruction? Can love save the world?
