A girl is having fun during a Japanese festival, catching gold fish.
The girl, wearing a kimono, is chloroformed by a creepy older Japanese man. She wakes up bound and gagged. The bondage scene is pretty lightweight for a hentai comic.
A separate chloro scene happens later in the comic, by the same artist. That one is...
From a doujinshi manga that I don't know the name of.
A girl with fishnets and boots is chloroformed in a parking garage. She is blindfolded and tape gagged.
From an adult manga. A woman is caught hacking into some computers, and is chloroformed from behind. She wakes up bound tightly and gagged.

Rikku is chloroformed by some men. They assult her while still holding the cloth over her nose. Unfortunately I don't think she passes out.
