I didn't have any fetish before watching anime regularly, but nowadays, I have them by the dozens.
With some of them being quite unique. It's amazing what anime can do, lol.
Strangely enough, they're mostly restricted to 2d girls. I think the 3 main ones would be:
- Mikos (this one applies to real-life women as well) - Yeah, I think I should probably get some common sense.
- Ama-loli (
or sweet lolita, like this)
- And the weirdest of all, women dressed in black and red clothes, like Yukiko from Persona 4 and Rin from Fate/Stay Night. I also like the uniform they use in Little Busters! (I also like the uniform the guys wear - but that's not a fetish though. I just think it would be cool if my uniform when I was in school was like Kyousuke's and co.)
