My first anime ever was probably Dragonball Z though it could also have been pokemon, cant remember which though too long ago and it depends which one was shown first in South Africa. Back then I didnt even know what i was watching was anime.
The same as previous post, looks like this anime did its job:
VAMPIRE KNIGHT was the series that converted me for good!!
( Pokemon but i didn't know it was one so i'm not really counting it.)Card captor sakura. We first had it in English dubs on VAS and i knew it had more to it (i always saw parts of other episodes before it started the 75min 3 episodes.). And one day my older sister bought all the episodes on dvd and brought it home and i watched it. I totally got into anime then next was one piece i think. Continued from there.( the episodes she bought were in Japanese subs)
Iv'e seen lots of anime like pokemon, naruto, stuff that was on tv. But the first anime that got me hooked was sekirei, i still love that series, and now iv'e watched lots of series and i still am going strong. (<^_^>)
