Broke off with the Nether King, the Saintess Regrets Madly

Hades, lord of the underworld, poured all his divine power and wealth into raising Aurora, the Holy Maiden of the Temple of Light, for 18 years. But on her coming-of-age ceremony, she publicly broke off her engagement and married the king instead. Meanwhile, the true reincarnation of the queen of the underworld—her twin sister Celia, whom she had bullied for years—reunites with Hades, awakens her powers, and together they defeat the demon king Lucifer.
