*You become an expert mercenary or warrior with fighting skills to match the best in the Kuroinu or Princess Knights. Alternatively you could be a formidable spellcaster in the same manner. Either way you are working on porn physics. Curiously you can wear stripper armor and still be as well protected as if you were wearing full plate, something about enchantments in the set of armor or so. It does nothing to keep you safe from rape though.
*You gain your own fortress of your own design that could be constructed in the setting of Kuroinu, it has a loyal population of whatever races you prefer. I wouldn't recommend rape monsters if you dont plan on feeding them any women. They at the very least wont sell you out or betray you unless you abuse them to a hilarious degree. This fortress includes a small military force to defend and police it, these are absolutely loyal.
*Optionally you can be transported to Kuroinu right around the time the Black Dogs have breached Olga's fortress. If you would rather not you can just have the Black Fortress sans monsters and the seven fortresses of the Princess Knights dumped into your world or just the women. Don't worry about Claudia's husband if you care for that sort of thing, he died. Or maybe not if you are the wholesome sort.
