Myriam Kordan is the French-dubbed name for Miki Koda. Secretly switched at birth with Nozomi Mine by nurse Michiko Nohara due to a grudge against the Koda family, she was raised in wealth by Sumiyo and the Koda patriarch. This upbringing fostered a sense of entitlement and a belief that wealth signifies superiority.

As a student at an elite music academy, she embodies the traits of an Alpha Bitch, using her family's resources to pursue her singing ambitions while disparaging those less affluent. She resorts to underhanded methods to undermine Nozomi, including framing her for theft and manipulating her during key performances. Her privileged life cultivated a Spoiled Brat mentality, leading her to expect constant indulgence and to rely on financial influence to settle disputes.

Her world shatters when Michiko publicly reveals the baby switch. Discovering her biological parents are the impoverished Mine family, and that her biological father Shinsuke Mine has recently died, triggers a mental breakdown. Consumed by identity crisis and grief, and fearing rejection by the Kodas, she flees home. This confrontation forces her to face her past actions, initiating a shift in perspective. After an intervention by Nozomi and reconciliation with Sumiyo Koda, she begins to empathize with others and acknowledges Nozomi as a sister.

Her journey culminates in familial integration as the Koda and Mine families unite. She accepts her dual heritage and moves towards personal growth, symbolizing a departure from her former elitism.
