This is a list of characters from Production I.G's Le Chevalier D'Eon anime series. The series is set in 18th century France, and its cast includes many characters that are based on real historical figures.

D'Eon de Beaumont (デオン·ド·ボーモン, Deon do Bōmon)

Voiced by: Yūki Tai (Young), Akio Nojima (Old) (Japanese); David Matranga (Young), Ted Pfister (Old) (English)

D'Eon is a member of the King's Secret, working in the shadows to keep the peace within French society. When his sister suddenly turns up floating down a river in a coffin with 'Psalms' written on it, D'Eon is thrown into a deadly struggle with revolutionaries and supernatural forces in order to uncover the truth behind his sister's death. He is loosely based on the historic figure, Chevalier d'Eon. Shortly after the beginning of the series, D'Eon is possessed by his dead sister's spirit, who manifests herself during combat and constantly mentions taking her revenge.

Ubukata had difficulty using a single character to portray D'Eon's complexity, so he opted to create two characters instead - D'Eon and his sister, Lia - and linked them together using "an occult process". Director Furuhashi mentioned D'Eon's "transformation" into Lia was different in earlier concepts; "His hair would grow longer and he'd turn into a woman. Meanwhile, his rosary would morph into a sword." Furuhashi worried that "D'Eon wouldn't be the historical figure anymore; there wouldn't be any point", so they conceptualized a less-fantastic transition between the two characters.^[1]

Lia de Beaumont (リア·ド·ボーモン, Ria do Bōmon)

Voiced by: Risa Mizuno (Japanese); Taylor Hannah (English)

Lia is D'Eon's older sister, who was killed under mysterious circumstances. Despite flashbacks of her being a caring and considerate young woman, who was well loved by the nobles and the royals, the spirit that possesses D'Eon is full of great anger, sorrow, and the desire to exact revenge.

"Lia de Beaumont" is the identity that the real-life cross-dressing Chevalier d'Eon claims to have assumed during a mission to Russia in 1756.^[2][3]

Robin (ロビン, Robin)

Voiced by: Megumi Matsumoto (Japanese); Tyler Galindo (English)

Robin is the Queen of France's young page who is assigned to assist D'Eon. Despite his age, he is earnest and resourceful, and his loyalty to the Queen and his companions is steadfast. Robin greatly looks up to D'Eon and his friends, and prefers to wield a flintlock pistol in combat.

Durand (ヂュラン, Juran)

Voiced by: Ken Narita (Japanese); Illich Guardiola (English)

Durand is a dashing man who is highly adept in the Florentine fencing style, wielding a rapier and main-gauche at the same time. He treasures his antique pocket watch despite the fact that it does not work properly. Durand's loyalty seems ambiguous throughout the story, but he appears to have once had affections for Lia. He eventually develops a fondness for Robin, taking the boy under his wing and even bestowing upon him his treasured pocket watch.

Teillagory (テラゴリー, Teragorī)

Voiced by: Haruo Sato (Japanese); John Swasey (English)

Teillagory was once D'Eon and Lia's fencing instructor, and is a well-respected knight from the days of Louis XIV. He carries an antique sword which was given to him by Louis XIV, and still holds onto the days of knighthood and honor. Teillagory lost his only son in a war several years prior to the start of the series. Ozaki used Anthony Hopkins in Mask of Zorro as the basis for Teillagory's character design.^[4]
