Lyra, the royal illegitimate daughter, had her contracted beast seized by her kin for sacrifice. Falling into the abyss, she awakened an amnesiac dragon king and gained a second legendary divine beast. She returned alongside the dragon king, reclaimed her child, exposed the false saint, and uncovered the ten-thousand-year lie of the Holy See. Eventually, she merged light and dark power to free the ancient dragons, defeated the Eternal Night Demon God with the dragon king, and gained freedom and true love.
