Hahaha :) mine was fairytail. I read the first 3 manga but then got bored with the whole plot. Now I just read whichever manga looks interesting. I've read Full Metal Alchemist and Slayers so far. I'm lectura a book about the history of Anime/Manga right now and I find anime and manga really cool because of how it's drawn and animated.
The first one I ever saw was probably Dragon Ball Z-Kai, but the first one I officially watched in sequence was Death Note. Of course my sister [IllusionDolls] has the same answer, because we watch a lot of anime together. :)
