It tells the story of the sudden appearance of the "Pillars" on Earth, threatening all kinds of life. Humans are helpless and forced into desperation, and at this time the god "Odin" reaches out to humans. Odin gives the Valkyries "Valkyries" and the Heroic Spirit Machines that become their wings to humans as a means of resisting the "Pillars" and declares a counterattack. Several years later, in the sky where humans and the "Pillars" continue to fight, the Valkyries wearing war wings and the men who support the Valkyries soar into the sky at the risk of their lives to save the world. Japan is no exception, with three Valkyries facing off against the huge Pillars towering over the sacred Mount Fuji. Each of them has powerful abilities, but they are all problem children. At this time, an ace pilot comes from Europe for some reason... "Come on, it's time to fight back, humans. The day of the final battle is coming-the twilight of the gods is approaching."
