Anne, also known by her alternate name Anghalhad, is a central character in the Four Knights of the Apocalypse narrative. She is a teenage girl with blue eyes and blue hair that falls to her shoulders. Anne comes from a privileged background as the daughter of a feudal lord, but she defies her father's wishes to pursue her own dream of becoming a Holy Knight, following in the footsteps of her mother.

In terms of personality, Anne is defined by her strong will and short temper. She is assertive, loud, and stubborn, often taking on the role of the self-appointed leader of her group of companions. Her temperament is best described as choleric, meaning she is emotional and unafraid to voice her opinions. Despite her abrasive and sometimes arrogant exterior, a trait fitting for a lord's daughter, she is deeply compassionate and practical. Her fierce loyalty to her friends forms the core of her motivations, and she does not hesitate to risk her life for them.

Anne's primary motivation is her aspiration to become a Holy Knight, a goal she holds with great determination. She joins Percival and his friends after they thwart a scheme by the Chaos Knight Ironside, becoming a valuable new companion on their journey. Her role in the story is as a key member of the Percival Platoon, the ragtag group of young adventurers who travel to the kingdom of Liones. Within this group, she serves as a grounding force, often contrasting with the more naive Percival and the intellectual Nasiens. She is a Fire-Forged Friend, having initially clashed with Percival before becoming one of his most loyal supporters.

Anne's key relationships revolve around her fellow platoon members. She shares a deep bond with Percival, Donny, and Nasiens, forming a True Companions dynamic where their loyalty to one another is unwavering. The group dynamic is often categorized as a Freudian Trio, with Anne representing the Id due to her emotional and impulsive nature. She is also known to be a fan of the Holy Knights, which fuels her ambition.

Throughout the story, Anne undergoes significant development. Despite not initially being a knight, her skills and dedication are recognized when the King of Liones, Meliodas, officially promotes her and her friends to the rank of Holy Knight after their arrival in the kingdom, bypassing the usual apprenticeship. Following a time skip, she becomes part of a resistance effort, working to gather intelligence and protect refugees from the forces of Camelot. Her growth reflects a journey from an arrogant, aspiring noble to a respected and capable knight.

Regarding notable abilities, while specific magical powers are not detailed in the provided search results, her combat capability is acknowledged by her promotion to Holy Knight. Her primary strengths lie in her forceful personality, which allows her to lead and make decisions under pressure, and her unwavering courage in the face of danger.
