|First Appearance||End of the Golden Witch|
|Portrayed By||Shizuka Ito|
Gertrude (ガートルード Gātorūdo?) is a senior member of Eiserne Jungfrau and a first-class priest. She wears a uniform similar to Cornelia's. She is a very charitable character, however, like Cornelia, she appears completely deadpan when on duty.
Gertrude appears as a woman with long blonde hair and wears 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.
Twilight of the Golden Witch
In the Tea Party, Dlanor reveals that Gertrude has been promoted to a lead Inquisitor since the events of Twilight of the Golden Witch.
- She has a tendency to say "Allow me to speak. Let it be said that ..." before declaring a Red Truth.
- In the manga adaptation of Umineko no Naku Koro ni, Gertrude's real-world parallel is described as a receipt stuck in a doorframe.
