I watched Dragon Ball Z, on CN without the knowledge that it was called "anime". So, I'm not counting it.
My first encounter with anime was when I was surfing the T.V. and stumbled upon the Animax channel. The show that was going on it was
Jigoku Shoujo(Hell Girl). The show immediately caught my attention it was so starkly different from what I was seeing till then on CN. I was 13 years old and the serious theme of Hell Girl was enough to get me addicted. Also, I had taken quite a liking to Ai Enma(she looked cute and her lines were so cool in english dub). The other shows that I watched on Animax also had a dark theme as having watched nothing but happy-go-lucky cartoons for so long I was addicted to the dark themes of anime. I think I watched
Blood+ alongside
Hell Girl. Well after that I was watching nothing but Animax
The shows I watched on Animax constitute a major part of anime shows I have watched till now(which is over 130, not much, I know, but still.)
