Temple of Ranma's Sailor Senshi Seifuku

This is an old fic (and not the fic by Togashi Gajinn) In it at some point Nodoka lets Ranma know she is actually Athena the Greek Goddess of Wisdom.

The go to some kind of "other dimension" where they can talk. I believe that it this fic is also a Tenchi cross -- but it's been so long that I don't remember.

I'm not very good at internet searches so if this is an easy find you have my apologies right up front.

Urgh. NODOKA is ATHENA?!

Hera, I could understand. Megaera, Tisiphone, or Alecto, I could understand. Maybe even Hestia. But ATHENA?

Color me gobstruck.

THAT would explain why the Greek Pantheon is Kaput.
