I, of course, am fine with more than a tongue getting jammed into my character's orifices, but other than that I'm in general agreement with TheHangedMan on the sexual stuff.<br/><br/>In terms of world-building and so on, I imagine a society with monster girls openly accepted would probably be slanted a little more towards having women in charge than men.  At the same time, one of the basic tenets of noir is that in the setting, the system of authority in place is hopelessly corrupt, so you could probably give us enemies in the police, in addition to enemies among the criminal element.<br/><br/>Of course, any good noir detective generally has an old buddy or two on the force, as well...<br/><br/>Corrupt politicians make good masterminds, as well. ^^ Also, if we're going with some of my other thoughts on the setting regarding borrowing a bit from the Monster Girl Encyclopedia pictures, then I'd imagine that the new demon lord responsible for all the sin and corruption could have been sealed away in the ancient past by some legendary hero, which would be the reason why she hasn't just taken over the world and turned it all into one big, never-ending orgy.<br/><br/>Demonic intermediaries attempting to unleash their dreaded master upon an unsuspecting world could make for one good potential plotline...
