Let's start from this one... where is this from? Of course GIS and IQDB were unable to help.
Then there was this manga I have a nebulous memory of.
I remember a guy was a protagonis, a mansion with traps, cameras and fake walls, and a lot of girls killed by traps or saved by the protagonist.
This one? Then again it's probably the exact opposite of what you're looking for. This is from Murcielago btw
