Ledania, daughter of a French town's mayor, holds local prominence. Her beauty features blond hair and a gentle demeanor, often enhanced by white attire that aligns with the Light Feminine archetype. This appearance draws widespread admiration from male peers at her boarding school, yet she perceives the attention as a burden due to conflicts among her suitors. Initially shy and reserved, she embodies passive innocence, fitting the Ojou archetype of a well-mannered young woman of status.

She harbors romantic feelings for Marion, a classmate renowned for intellect and rationalism. During rainy weather, she confesses her love to him. Marion, preoccupied with his affair with an older woman and emotionally conflicted, rejects her harshly. The rejection causes visible distress: she slaps him before fleeing in tears, intensifying her isolation and heartbreak.

Within the narrative's romantic entanglements, Jacques and Lind vie for her affection, escalating a dangerous rivalry. Her unreciprocated feelings for Marion remain central. After Claude's suicide and the friend group's unraveling, she seeks solace from Sara, the older woman involved with Marion. Arriving distraught at Sara's residence to report Jacques and Lind's impending duel, she receives physical comfort as she cries.

Her character development is minimal and reactive. Resolution diverges between adaptations: the manga suggests her acceptance of Jacques's affections, implying a potential relationship after the summer's tragedies. The anime concludes with her emotionally overwhelmed, leaving Jacques's proposal unanswered and her future uncertain. Her narrative function symbolizes lost innocence and unfulfilled love within the story's exploration of adolescent turmoil.
