Description
Chloé d'Apchier was born human into the noble d'Apchier family. She became a vampire at age four during the Babel Incident, freezing her physical development at eleven. Her family concealed this by faking her death, confining her to their estate and forbidding her to reveal her face. Generations of d'Apchiers researched the World Formula, initially seeking a cure for her vampirism, though their goals later turned political.

She resembles a prepubescent girl with short silver hair, large gray eyes, and pale skin. Despite her childlike stature, her expressions convey maturity and severity. Her eyes sometimes shift red, a vampiric trait. Residing in Gévaudan's Silver Forest, she is known as the "Silver Witch."

Her personality blends stoicism with fierce loyalty. She upholds her family's duty to protect their domain, declaring she could "never hate the d’Apchiers’ people" despite their scorn. She shows deep affection for those she considers family but harbors intense jealousy and vengefulness towards their harmers. She often disregards social boundaries, displays curiosity about outsiders, and finds solace in nature and machinery.

Key relationships define her. She befriended the vampire August Ruthven during the war, but their bond shattered violently after she discovered Jeanne's enslavement as a Bourreau. Jeanne, whom she met as a child, became like a sister; Chloé eagerly awaited their reunion for over a century. Later, she rescued the abused vampire Jean-Jacques Chastel, adopting him as her "one and only."

Her powers include innate vampiric abilities and specialized knowledge. As one of the oldest vampires, she possesses superhuman strength and speed, easily overpowering adults. She mastered the World Formula Alteration Device, a family invention enabling reality manipulation. After willingly contracting Malnomen for revenge, her curse "Millie, Theater of Ice and Snow" manifested as energy lashes and gravity distortion. At its peak, the curse transformed her into a destructive mist generating wolf-like familiars, requiring external intervention to cure. Her true name is "Canorus," meaning "She Who Plays the Melody of Snowflakes."

Her story centers on the Beast of Gévaudan arc. As vampire hunts escalated, the Catholic Church fabricated the "Beast" narrative to conceal killings. Jean-Jacques sacrificed himself by becoming the Beast to end the hunts, offering his true name to Naenia. When Jeanne arrived to kill Chloé—mistaken for the Beast—Chloé attempted suicide. Surviving, she bargained with Naenia to become a curse-bearer for vengeance. She later unleashed her Malnomen against Jean-Jacques's harmers but was ultimately cured through Vanitas's Book of Vanitas and her own will to live.
