As you guys know, I have the full Anime and Manga sets for Death Note (WOOT!) and Attack on Titan (plus the spinoffs!). While most fans of a particular series usually favor one over the other–I’m referring to Anime or Manga–some are so good, you don’t mind experiencing them through a second lens.
I picked Death Note and Attack on Titan as examples for another reason: The storyline is virtually unchanged in the conversion from Manga to Anime. You can literally quote chapters from Death Note while watching same scenes in the Anime. In the case of Attack on Titan, I started buying volumes after watching the Anime for the first time on Netflix. As I mentioned in my review of the Anime last year, The Manga continues the story after the series (or rather now the first season) starting with Volume 9. If you never read the Manga, you’d be in the dark about alot of things going on as well a how Levi’s past and what happened during the time of Commander Ervin’s Predecessor tie in to what’s going on now. Death Note does have prequels too of course but they were written after the original series was done to add on to the storyline. The BB Case L references early on gets a miniseries in Manga form. The third Death Note Movie L Change the World takes place during the space of time between when his name is written in the Death Note and when he dies.
Of course, not all series with both of Anime and Manga either get a US Release (History’s Mightiest Disciple Kenichi) or stay true to the Manga (The first Fullmetal Alchemist series). The original Dragonball Z Anime (292 Episodes) drew alot of heat due to the huge amount of filler added to extend the Anime. DBZ Kai is almost half as long (The rest of the remaining Sagas are currently in production in Japan) but is prettymuch the same story just WAY shorter.
Code Geass is an interesting example in which the Anime came first. The Manga is the same story minus the Knightmare frames used in the Anime. Most folks already know this but Naruto Shippuden doesn’t “exist” in Manga form. All volumes after 29 fast forward to Older Naruto in the Manga. They had to add a subtitle to the Anime for licensing reasons.
