I have this idea that is based on an anime that I saw sometime ago.
Basically in another universe these two species of humanoid beings are fighting with one another. Each believing that the other is out to destroy the universe. Essentially, they have been warring for so long that they no longer really know what or why they are fighting anymore.
Anyway, the kicker is that one species is made up entirely out of females and the other entirely out of males. The general idea that I have in mind is that my character (female) ends up somehow stuck alone with the other character (male).
I have the first post written up and waiting for posting. I prefer a partner who can write well, is patient and can add to the overall story to the point where I am not the only one dragging us along through it all.
