The first manga that I fully read was one of the Bleach ones, and it was during math class when I had nothing else to do (Why my math teacher had manga in her class, I have no idea.) But that's probably going to be the only manga that I ever actually read. I prefer anime.

My first anime that got me hooked on anime was I think Shugo Chara. I never finished it, though, because I moved on to animes that were more to my taste halfway into it. (Soul Eater, Elfen lied, things like that.)
