I've watched the first season of the Kore wa Zombie Desca / Is This a Zombie anime simulcasted on Crunchyroll and the bought the first volume of the manga on the Yen Press app for iPhone.
Geez, only one named so far, and my first choice is already taken? Well, I suppose I could post Korezom again, but I can think of something else... Oh yes, I've watched and read Trigun! :D
(Pic is my FAVE character XD)Kore wa Zombie Desu Ka, it BY FAR the best series I have both read and watched... But there ARE more! There's ToraDora, High School of the dead, Fruits Basket, Dance In the Vampire Bund, Rosario+Vampire, Hikaru No Go, Ouran High school Host club, and finally, Needless.
I've read the Ouran Manga (which I did first to see how I would like the series) and it turned out I loved it and then I went to the anime and I loved it,also read the manga and watched the anime of Vampire Knight as well,did the same exact thing read the manga first than went to the anime.
Rosario's another one that I watched ऐनीमे and read मांगा for. I "paused" पढ़ना the मांगा while I finish the anime, and will then resume the manga, which I'm assuming goes "further" than the anime.एक साल से अधिक पुराना
Gunsmith Cats is another one of the first manga that I started reading (about 15 years ago), primarily because I had watched the anime for it.
This forum is kind of an experiment. I noticed that they now let you comment directly on other people's forum posts, so if you post a "Post a ..." question in the forums, you can now respond directly to a post and post more than one if you feel like it. I suppose you can't vote for a "best answer" though, so that might be one reason to keep using the Answers instead.
I haven't read much manga yet, and some either doesn't have, or I haven't yet watched the anime version. Rosario Vampire is the only one where I've done both. I saw the anime first and then read the manga and I have to say, the manga sort of ruined the anime for me a bit because it was so much better.
Katekyo Hitman Reborn! - I got addicted to the anime way to much, so I read the manga so I could see more of the action. XD I got really sad when it ended. :(
Kimi ni Todoke - I got hooked on the anime, and wanted to see what would happen next in the manga. :D
Vampire Knight - Pretty much the same as Kimi ni Todoke
The World God Only Knows - This one is slightly different. I started reading the manga first because there wasn't an anime yet when I was starting to read it. XD
Fairy Tail - Same reason with Katekyo Hitman Reborn!, but the only difference is that it didn't end yet.
Bakuman - Same as Katekyo Hitman Reborn!, but I wasn't disappointed with the ending. ~
And soooooo many others. XD I can't type them all here though. ~
Oh Naruto comes to mind I've read the manga and watched the anime,and Dragon Ball Z as well,but I watched my first Dragon Ball Z episode years before I read my first DBZ manga haha,also I've read and watched Yu-Gi-Oh!,oh and I can't forget my First Ever Anime and Manga which is Meitantei Conan!
