The girl in this story is kidnapped twice. The first time, the bad guy tries to chloroform her, but she manages to fight him off. The second time, she's kidnapped and probably KO'd off panel. We see a shot of her unconscious with her hands taped together.

Remember that great scene where Miu was shown knocked out and unconscious for many chapters? This is how she got KO'd. In a big chaotic fight sequence.

Eureka, the main female protagonist of this series, is briefly knocked out while piloting a mecha robot.

In this bondage themed manga, the main female character is KO'd via neck chop (minor scene). She wakes up tied up. The story revolves around people trying to violate her "chastity belt", and when they succeed, I think she turns into this dominatrix type heroine. Anyway, that's how the other people get tied up....

Really good scene here featuring police investigator Hibino Miduki. Miduki goes undercover with some Japanese mafia members. She pretends to be an escort, I think. When things get too heated, Miduki pulls out her police badge, revealing herself as law enforcement. The gangsters don't take kindly to this. One larger ma...

Two high school girls are kidnapped while on campus (kidnapping happens off panel, darn). Supposedly the girls are good at martial arts or something. They wake up while captive. Sometime later in the same volume, they are on the grass unconscious. Again, it all happens off panel.

Very good drugged drink scene. A woman is having dinner with a man; the man places some sort of powder in her wine. The woman is knocked out pretty fast. The man gropes her a little. The following panels show the woman sleeping peacefully. Towards the end, the man replaces her clothes with fetish gear.

Very minor scene, I have no idea how the girl is KO'd. When a woman disguised as a nurse walks in, the blonde haired girl falls asleep. The nurse has some aura about her.
