Elias was originally the son of the God King, but his divine power was constantly drained by his foster family, and he was also bullied and plotted against by his stepbrother Sevien. When the village was attacked by a demon dragon, Elias awakened his Titan power, but Sevien stole the glory of slaying the dragon. During the knight selection, he was repeatedly framed, and Princess Ariadne protected him. Later, Sevien betrayed the kingdom to the Abyss and attacked the royal capital. Elias combined his Titan power to defeat the villain and married the princess. In the end, he set out again to rescue Olympus Mountain, which was surrounded by demons.
