I was around 13 - 14 yrs old, and still watching cartoon network when most people had stopped around that age. I when onto YouTube in search of something related to Ben-10, (can't remember what). I then saw a video in the related videos section that said "kyubi 8 tails transformation". I was presented with a blonde hair kid clad in a orange cloak who I now know as Naruto, I bet you didn't see that one coming huh?
Anyway long story short I got hooked on Naruto, found out that my friend had been watching anime too. He also informed me of all the time I wasted on watching "filler" episodes and my love for anime took off from there.
