First saw One Piece when I was around 5, but I wasn't following it weekly. Just used to watch it with my older brother. I'm 19 now. Watched it weekly in 2011, Marineford.
I was on and off with the anime untill 2015 where I picked up Dressrosa in the manga. I've been reading the manga on and off since.
For the last year, I've been reading every single week the second it comes out.
