Looking for a very old story

[MegaDan]

I'm looking for an old Tenchi Muyo story called "Aerin's Assault" (or something like that, as I don't recall the spelling for the title.). The premise was that Mihoshi and Kiyone were captured by this Aerin (sorry if the spelling fellow and tickle-tormented in order for Aerin to find out where Ayeka was.

I hope someone has it, as I've been trying to find it to add to my collection for a while now.
