Sasami the girl who first got me into anime loli right at the end of the 90's. Back then I was in the denial stage feeling a little guilty over having a thing over a loli character.
A few years later I started watching Card Captor Sakura and found myself becoming very attracted to Tomoyo. Not long after that was Nadesico and like many I had a thing for Ruri-chan.
It was all down hill from there.
The real question for me now is what was it that first set me of with animal ear girls. LEE's Minimimi ero manga was an early and major influence way back when but I'm sure there were was something even before that.
I had a minor loli-phase in early 2012 which I supposed never really ended. I love petite and small framed characters at first sight, but hate when they get treated badly (raped, killed) in canon. My favourite loli-pettanko fanarts are especially consensual romantic implications like this image.
