Katrina

Not a maid. It's a temporary costume.

Katrina is a minor antagonist working with and introduced "along" Zaki (Zaki is introduced earlier, but Zaki is confirmed as an antagonist with the introduction of Katrina).

Katrina is honest and cold, and doesn't seem to like people very much, unless she is in an environment related to cooking, serving meals to people, etc.
Katrina recently received abilities and started working for the Goddess Áshiho, and Zaki, Áshiho's son, is now her superior as well. But Katrina doesn't respect Zaki, as she considers herself to be smarter than him, which, she isn't wrong.

Katrina has a love for cooking but all of her foods are "very okay".
Katrina hides inside the kitchen sink cabinet to eat ice cream.
At night, Katrina walks around with a basket to offer food to her neighbors. Haruka knows her from it.
