Gracie DeLuca

She is the daughter of Cordia DeLuca and Lucan DeLuca. She is sister of Antonio DeLuca and Luna DeLuca.

Gracie, who is adamant about joining the family business, trains under Wilfred albeit behind her mother's back. Lady Cordia does not want Gracie to enter the family business and opts for her to make friends and lead a normal life. This often leads to instances where Gracie sneaks off on dangerous missions when she is not permitted to.

While Gracie is known for her sharp intellect, she is lacking in social skills. At one point, Wilfred evaluated Gracie's skills and found that she is an S-Rank in all of her attributes (which is very high and rare.) She is very agile which is due to her practicing ballet in her free time.

While The MC helps Gracie with her lack of social skills, he also helps her with her rivalry against Isabel DeLuca. Gracie dislikes Isabel due to her joining the family by marrying Antonio, her brother. She feels threatened as she thinks Isabel may steal her brother away from her. While angry at first, they eventually settle this dispute and become close.
