Laugh all you want at the ridiculousness of this scene, but I think what they do to this woman is dehumanizing. They chloroform her, and while she's asleep, they install her into a wall mount. Kind of like those 'moose heads' or 'bear heads' you see on hunter's walls? They put her in that, and gag her. Source: exhenta...

This Lum gassing scene has a corresponding anime version. In this set of images, I included a few good "peril" shots of Lum, and one decent pinup I found. The main crux of this scene is Rupa, the villain, kidnapping Lum by gassing her with a "mushroom". The same mushroom gas technique is used later on a bride during ...

The gagged girl still has use of her arms, so she fights the guy. They tumble off a balcony. Something weird happens after,...

He then binds her hands with tape. The guard then tries to rape the girl, but before he can, another male employee stops him. Interesting side not...
