I distinctly remember the series continuing with at least one story where all three girls get together to take down a gang and I think there was a reunion type story that took place a decade or so after the originals with the three girls having become women.
Yes, I have the whole series (but not the "last" story, that I haven't written yet) on Hard Disk. I need to do an edit of it, then I'll post it (eventually).
It will take a long time, as I have other stuff going on at this time (supporting a 100 mile Foot Race up in the Angeles Crest Mountains, then a three-day Anime convention, then another two-day anime convention earlu next month).
Keep reminding me over on Jack's/SP's Board so I don't forget.
