Description
Charles D'Artagnan is a character who appears in the anime Samurai Bride, known to those close to her by the nickname Nia. She is a tall young woman with blonde hair, distinct for her Western-style hat adorned with a feather and a striped fur tail, as well as her attire which includes a purple and gold open shirt, a frilled teal skirt, and detailed steel gauntlets and leg guards.

As a foreign transfer student from France, her background is that of a diplomat's daughter, which initially brought her to Japan and to Buou Academy. She is a descendant of the legendary 17th-century soldier whose name she carries. Her personality is characterized by a gentle and somewhat shy nature. Despite her formidable presence in combat, she is kind-hearted and possesses a strong sense of loyalty to those she cares about. This loyalty is a core part of her being, even when tested by difficult circumstances.

Her primary motivation and key relationships are deeply intertwined with Yoshihiko Tokugawa. She met Yoshihiko while making origami and developed a romantic affection for him. However, this relationship was built on a betrayal, as Yoshihiko used her as a test subject in his experiments to create an artificial Master Samurai. Despite this profound breach of trust, her feelings for him persisted. She remains fiercely devoted to him as his contracted samurai, following his orders even when they are difficult.

Charles's role in the story is that of a loyal retainer and a powerful warrior. Initially an artificially created Master Samurai bound to Yoshihiko, her narrative arc culminates in a moment of great sacrifice. She dies protecting Yoshihiko from falling debris, clutching an origami samurai helmet he had given her in the past. Her death serves as the catalyst for Yoshihiko to realize his true feelings for her. He revives her, and through this act, she is reborn as a true Master Samurai, marked by a concentrate symbol on her left hand.

She is noted for her significant combat abilities. Her fighting style is unique and powerful, wielding two large double-sided claymore swords simultaneously. She is capable of performing a Mode Change, which allows her to augment her fighting strength tremendously by utilizing different elemental attacks. This ability, however, takes a great toll on her body, requiring time to recover between modes. Her strength and training are such that she can move with great speed and agility despite the considerable weight of her heavy, steel-lined clothing and equipment, which together weigh over thirty kilograms.
