I had seen this anime/movie when I was pretty young, so it's probably from the late 80's early 90's. It was also dubbed in English.
I vaguely remember the scene, it was with a man and a dark wolf like creature. I assume the wolf had just finished doing a killing/deed. The man congratulates her(the wolf) saying something like, "You did good work, you can have the rest of the day off." As to which she replies with glee, then turning into a woman. I think she had dark hair, perhaps purple?
The scene then cuts to her blissfully taking a shower. When she finishes, she walks into a hotel room where there's a robot. (For some reason the only comparison I can think of is Wheatley from Portal2.) To which when the robot sees her, "malfunctions" as a response to her being only in a towel.
I can also remember that the hotel overlooks a city scape, though that's all.
