To clarify there are people working on new SlaveGirls using the SDK.
Orihime is the first one released by Daisy_strike and is included in the full install for version 15.8. The are others but in early alpha releases and are linked in the forums. They are graphics only girls with no story. Currently Ino from Naruto, Aeris from FF7 and Menace. Ino and Menace are quite advanced in development
Multiple others are mentioned in development, notably
Asuka from Evangelion
Bulma from Dragonball
Menace from Queen's Blade (advanced progress
early talk of Reimu from Touhou
I am working on
Rei from Evangelion
Krystal the Star Fox
in various stages of development, Rei is quite close to a basic release, mainly once I finish the new version I will finish her in a few days.
Otherwise development is going well. Some NPC changes, mainly for graphics used, some variant images and some people now have images, and names.
The remaining tasks is still the same but quite advanced. I am confident of a beta test in about a week
