Camille Blanche is the heir apparent of the aristocratic Blanche family, proprietors of the Galerie du Roy shopping arcade housing Claude and Oscar's metal shop. Her position entails significant responsibility for securing the family lineage through a marriage alliance with equivalent wealth, imposing strict societal expectations that curtail her personal freedom.

Her high-class status is visually reinforced by an elegant demeanor and adherence to era-specific fashion, including crinoline skirts and corsets. The narrative consistently employs the "caged bird" metaphor to illustrate her confinement within aristocratic obligations. While her younger sister Alice openly envies Camille's perceived elegance and status, Camille herself embodies resignation regarding her prescribed role.

A past connection exists between Camille and Claude Claudel, the metal shop owner, suggesting a potential romantic relationship thwarted by their differing social classes. This history fuels Claude's resentment toward the Blanche family. The series implies Camille harbors unresolved feelings for Claude but remains bound by familial duty, unable to act. Her character maintains this state of constraint throughout the narrative.
