Strictly brainstorming ahead...
Hmm...an AU...mixing ideas from various ideas running through my head and things that I've seen. Our 7 Ghosts, living out on a barge. If you've seen Jackie Chan's 'Myth', you know why I chose a barge. Much room to be had.
Actually, the idea came while watching re-watching Bakuretsu Tenshi just a while ago...but instead of just one 'Jo', we have multiples.
Also mixing in some ideas from FMP, Highlander and the like...sorry, no mechs.
Miria = Sei (leader)
Deneve, Clare = Jo-ish
Helen = Meg
Tabatha = Ami (hacker)
Cynthia = (sometimes cook, sometimes inventor)
Uma = newbie
Raki = the one wuss BakuTen hired as the real cook.
Ophelia's in this one - you can GUESS as to who she's gonna be.
