Rumble— BOOM!!! The dimension of the constellations is torn sharply across the ashen sky. On the burning earth, the moment a massive fragment of one of the five legends—once called myths—is driven into the ground, half of the world he governed silently disintegrates into cosmic dust. Amidst the ear-splitting explosions and screams, Parang, then just a boy, could only watch the carnage helplessly. The cruel laughter of villains tearing out the hearts of legends to gain power. And the back of Nero, his other half, who smiled coldly as he was ripped away from Parang's soul. That nightmare of a destroyed past continues even now. "…Another place has been erased." On the surface of the devastated Gagangjeon battlefield, thick with acrid smoke, Parang—now grown significantly with eyes that have turned completely cold—mutters under his breath. Around him, four companions who lost their respective worlds and banded together solely for revenge and survival catch their breath and grip their weapons. Two fragments of the legend have already fallen into enemy hands, and the speed of the world's collapse has become uncontrollable. Parang looks back at his companions with glowing blue eyes and speaks in a quiet but heavy voice. "I won't let the tragedy of the past repeat itself. If we lose this fragment too, the world we're standing on is next. …Let's go."
