Camilla

Camilla is one of Yor Forger's three co-workers at Berlint City Hall. Camilla is initially shown to be snobbish and mean, inviting Yor to a party simply to make fun of her being single and attempting to spill hot gratin on Yor. Despite her thorny exterior, she has a soft side and accedes to patiently teach Yor cooking when she pleads, despite her initial frustration.

Camilla appears to live alone and seems fairly wealthy, having a two-story house large enough to hold a party in.

She seems to be a good cook, being able to recreate Yor and Yuri's childhood stew from just their memories. She is also knowledgeable about cooking variations from other parts of Ostania as she adjusts the recipe after asking about Yor's hometown.
