In Their Own Story

The sky above the Underworld fractured, bleeding light that tasted like ozone and old blood. Issei stood at the precipice, his crimson armor humming with the weight of two dragons' wills. Before him, the gates of Heaven opened not in glory, but in a terrifying display of judgmental fire. 'It is time,' the voice echoed, shaking the foundations of the world. He tightened his grip on his gauntlet, feeling the familiar warmth of his friends behind him. There would be no retreat, only the final stand for a future where humanity could breathe free.
