Lucifer was once the most dazzling Morning Star in Heaven; however, after refusing to carry out an order to hunt down the divine offspring living among mortals, she was stripped of her divinity by God and cast down to the mortal realm. Living incognito under the name "Lucia" in the seaside city of Poseidonia, she led an ordinary life working part-time jobs. Three years ago, she met Adrian, a young painter down on his luck; unbeknownst to her, the innate power of her angelic essence transformed into a blessing that enveloped him, propelling him from obscurity to become a red-hot rising star in the art world. Lucia attributed this transformation to the power of love, believing their relationship was strong enough to lead to marriage.
