The Awakened Fate Ultimatum is a story-driven rogue like RPG. Several years after a certain revolution came to pass, and the powerful Nathanael was defeated, the devils were still dominant in their constant war against the angels. Meanwhile, a certain Celestial was resorting to guerilla warfare to survive. The angels focused on researching a way to create a "God" to use as their ultimate weapon against the devils. After creating the "Fate Awakening Crystal," which can turn a human into God, the angels awaited the day to find someone who would be compatible. Walking home from school in the human world, a boy is attacked and stabbed through the heart by a group of devils. As he lay dying, his life is saved by a mysterious girl. He wakes up in an unfamiliar location-Celestial. As if guided by the Fate Awakening Crystal implanted in his chest, he finds himself thrust into the middle of the war between angels and devils. He must harness his newly awakened powers, choose how to use them, and ultimately decide which of the two new girls in his life he will do anything to save.
