Flora Fanfani, step-sister to Princess Angelica in the elven kingdom of Rothschild, is barred from succession as Queen Christina is not her birth mother. Effectively held captive by the queen, she endures a magical curse that forces her into a daily catatonic, vegetative state, rendering her helpless and unable to resist her confinement.

Ernesto, a human harboring a vendetta against the royals, intervenes and successfully breaks Flora's curse, freeing her from the cycle of paralysis. Liberated, Flora develops intense gratitude and devotion towards Ernesto, which deepens into romantic love. She begins calling him "onii-sama," signifying reverence and submission. Flora willingly submits to Ernesto, aligning herself with his plans and becoming a devoted follower in his campaign to undermine the kingdom's leadership.

Her character possesses light green hair, yellow eyes, and pointed elf ears. She wears a dress and often adorns her waist-length hair with a bow. Flora's narrative arc traces her transformation from a magically imprisoned figure to an emotionally dependent accomplice under Ernesto's influence.
