Hmm, how about something like a Sci-Fi war?
There would be the TG Aliens, BE Aliens, TF aliens. Kinda like rock paper scissors. TG>BE>TF, and Subi-chan would see the 'cruel' ( :P ) ways that the aliens change their victims into their own species to help them in a galactic war.
The TG aliens would turn men into Space women, the BE aliens would kidnap the space women and 'improve' them, and the TF aliens would kidnap the new and improved space women for another change.
My movies are all focused on TG, but if you want you can use their plot lines.
Other then that, any MtF moments in the comic would be great.
