I saw this on tv on what I believe was Animax about 20 years ago. I remember a boy and a girl on a bike/motorcycle, the girl was sitting behind and was crying about being A MACHINE or something. I think she was turning into something?? It was it the middle of the day too

Im sorry, it's such a vague memory I have and I just remember it from time to time and always wondered what anime it was.
