It's a Tenchi Muyo fic.  I just finished watching Episodes 8-13, and the
one with the baby got me thinking.  What happened to Washu's decendants?

Well...  you'll probably get a few emails on this, but the consensus
around here is that the few clues provided in that and other episodes
suggests that Mihoshi is Washuu's granddaughter...

But don't let that stop your fic!
