Mixed-blood girl Stella suffered endless bullying from the Aurora Corporation, and after being framed, was abandoned in the perilous Black Street. Lucian, the head of the Obsidian Family, rescued her, recognizing her as his destined queen. Amidst a series of life-and-death crises, Stella awakened her dual bloodline of light and shadow. She broke free from her shackles, sought revenge against the forces that once trampled upon her, crushed the Archbishop's plot, and transformed from a discarded girl, vulnerable and at the mercy of others, into the supreme queen ruling the city, standing united with Lucian.
