|First Appearance||End of the Golden Witch|
|Portrayed By||Asaki Risa|
Cornelia (コーネリア, Kōneria) is a member of Eiserne Jungfrau, the 7th District Repentance Enforcement Agency of the Great Court of Heaven, Assistant Inquisitor and a third-class priest. She has a strong sense of justice and is hot-blooded by nature, however, like Gertrude, she appears completely deadpan when on duty.
Cornelia has obtained high grades in academic exercises, and is cramming for exams to become an Inquisitor of Heresy like Dlanor. Her current goal is to become more like the veteran assistant, Gertrude. She normally has a zealous personality. However, she imitates Gertrude and tries to be emotionless. She is too innocent and pure for one connected to heresy hearings, and she doesn't yet know of dirty jobs and the dark side of this profession. Gertrude intentionally selected her for this mission, which stinks of a plot within the Senate. She did this to make Cornelia check and see whether she really was suitable for this sort of job.
Cornelia appears as a young girl with red eyes and bobbed brown hair decorated with yellow ribbons. She dresses in the standard Eiserne Jungfrau uniform: a black leotard with blue leg o'mutton sleeves, a white collar, white tie, white cuffs, and white stockings with black shoes.
Cornelia is somewhat meek, especially compared to her counterpart, Gertrude. She holds a firm belief that regulations exist to be enforced and is uneasy with breaking rules.
Twilight of the Golden Witch

- In the manga adaptation of Umineko no Naku Koro ni, Cornelia's real-world parallel is described as being tape.
