Episode 001: Section 9 (2010)
Author + Illustrator: Yu Kinutani | Page Count: 248
A number of cyborg Geishas have taken clients hostage, among them a high-ranking government official who at the time of his capture was engaging in some odd activities with the pretend ladies.
The Prime Minister summons the country's best counter-terrorist unit: Public Security Section 9. Led by the cybernetically enhanced Major Kusanagi, the team are called upon to not only resolve the situation, but to find out who's behind it, and why.
It's a manga adaptation of an anime TV series that was inspired by a film adaptation of a manga. If you're familiar with all of those things, then the book might be of interest to you, but know that it's the entire first episode of the GitS SAC anime in manga form - it's almost verbatim, except for some minor changes in the action scenes that don't alter the main storyline one bit. It's arguably less fun than watching the anime, so is probably best recommended for super-fans or folks who prefer manga, only.
