I Am Actually the Final Boss

The old era ended in blood and fire like falling leaves, buried under the dark and cold embers. And above the embers, in the new era born of technology and steel, who will be the first to glimpse the mysterious end? Who is dancing among the murmurs of all living beings? Who is spying at the mysterious end? Mysteries are rampant in the steel city, and a dark shadow covers the earth and sky on the throne of the past. Mystery and blood, sky and earth, in the torrent of changing times, who is singing the eternal epic? When the king crucified on the throne is reborn from the ashes of the old world, the door of the era opens with a bang, and the torrent of change is unstoppable.
