Fact is, a lot of young women are hardcore anime fans. This is even truer with the Internet, which popularized the medium even more. The only problem is that most of them are nerds, so you probably don't find many hot anime fangirls. However it wouldn't be a problem for me, since I always favored cute, intelligent girls instead of hot girls, and I like shy girls with glasses.
Wouldn't it be a stroke of genius, a match made in heaven? To be with a woman who'd have a lot of interests in common with me? Who'd also be an RPG fan, and would care less about having a huge social status? Who'd be introverted and would allow us to watch anime and play games together, without having to meet tons of idiotic friends? It would probably be very easy for me to impress them with all that I know in every nerd hobby known to man, and how well and intelligently I'm able to express it.
God, it makes me even more aroused than thinking at anime women.
