Do you mean How did i come to know OF anime?
Well i was sitting in the lunch room in my ninth grade year and a friend introduced Naruto to me. She is VERY special even to this day XD
If you mean how did I know about anime,it all started when I woke up to a Case Closed Episode on Adult Swim!..but it took me a week or so get adjusted and re-think things over,because it scared me at first!..then in that span I thought of re-watching it..although it was very hard for me to get at 5:00/5:30 a.m.,but anyway I re-watched it and I got hooked on anime every since!
well....My father was watching detective conan...when I was A kindergartener.... my father told us that..."Here guys...Detective conan is so awesome....you should watch it" when we watch it the whole episode...We said to him that "Woah!!! So cool...what is that??? Cartoons???" Then my father answer me "Nope, It's not a cartoon...It is anime"....then my life was full of anime!!!
I founded it by accident when i was having a holliday with my parrent i checked the TV Chanel and then i found out animax the first anime i have ever seen is Hayate the combat butler the episode when hinagiku meets hayate i really think that hayate the combat butler is shakugan no shana back then
I'm going to assume that you mean "How did you discover your favorite anime".
I was once a frequenter of ThatGuyWithTheGlasses. When I was searching for 5 Second Movies, I came across one called "Rosario + Vampire in 5 Seconds". Needless to say, I checked it out. However, it wasn't the clips used to make "5 Seconds" that interested me. Rather, the video showed the clip from R+V Episode 5, where Yukari bit Kurumu's boob.
It's thanks to both that video and the boob bite clip that I got interested in Rosario + Vampire.
