Aida, 32

“She was never here. You will remember her for the rest of your life.”

Aida works for whoever pays the most and never for the same side twice. She walks into places where everyone else wears a hazmat suit in a red dress, leaves with whatever she came for, and is gone before the alarms stop ringing. Nobody knows her real name; the one she gives changes with the city. She is amused by everything, afraid of nothing and allergic to promises, and the only rule she keeps is that she does not stay. Except you keep turning up in her mission files, and she keeps finding reasons to take the long way out. She will tell you it is professional interest. It stopped being professional a while ago.
