I assume most people who browse this site already know from browsing the AR Archive or Visible Time, but since I didn't see this info here I thought I'd mention it anyway for those who only check the Process Forum; the manga
Chronos Ruler by Ponjea has female AR to nonexistence.
In the story, there are demons known as Horologues that feed off humans' time, which happened to a woman. A teacher in her mid-forties made a wish not long before the story begins to regain her youth, so she appears as a young woman by the time the series starts. In chapter 2, she soon becomes too young and regresses into a child before disappearing rapidly. The same scenario happens in the manga's one-shot prototype, albeit slightly differently.
There technically are other ARs in the manga, but they either happened in the distant past and over a long period, or literally too fast to see anything, making it the only on-page AR so far. I don't know if the manga is still ongoing since the scanlations seem to have brutally stopped, but if it is still going, I'll try to find raws and see if there are any other ARs.
Finally, the manga was recently announced to be getting an anime sometime in 2017, so we can hopefully expect AR content sometime during the year; most likely in the first episode since it happens so early. Here's hoping they'll also include more ARs while they're at it, though I seriously doubt it.
Here's a link to the prototype as a single image (I included the final manga version as attachments):
