I got the comic. The first story has an incredible chloroform scene, with sleepy shots and everything.
This comic in total has:
1x hypnosis (plus carry)
and a lot of bondage.
Buy the comic! It was only $5.95.
Alright, this may actually be my MOST favorite Empowered scene ever...and it doesn't even involve chloroform!
Empowered has just completed her mission, and is walking triumphantly through a hospital. She's suddenly grabbed from behind, with a gag shoved over her mouth. Turns out the villains of the story aren't done...
The same catgirl/maid is tricked by some creepy dude, and chloroformed with a plaid cloth. Next scene, she is bound and gagged. Some nudity involved later. Great chloroform scene!

All three girls get gassed by a woman weilding a spray can. They wake up bound and gagged. Nice scene!
Side note: This manga has a lot of bondage in it, but most of it is not appropriate for this site.
