Maren Morgan, betrayed by her family and fiancé Wilbur for her half-sister Nadia, regains her lost memories, revealing her true identity as the sole successor of the Sovereign Underworld. She immediately breaks off her engagement, demands her inheritance, and takes control of the Onyx gang in Baimsa. Seeking revenge against those who betrayed her, Maren participates in a car race, where she ruthlessly eliminates Marcus Lee, a former subordinate turned traitor. She then leverages her enrollment at the Royal Military Academy, challenging the dean to accelerate her graduation and secure her shares. In a field combat assessment, Maren systematically outsmarts and eliminates her classmates, including the conniving Nadia and the arrogant Wilbur, who constantly underestimate her. This marks the beginning of Maren's fierce comeback to reclaim her rightful place and exact vengeance on all her betrayers.
