This time around the most interesting change is the new section for Tiger & Bunny, which was split out of “Anime (Sunrise)”, and starts out with an enormous 1109 circles; the rest of Sunrise was left with only 269 in the process. Since most of the other girls’-side genres – Reborn, Gundam, short stories and Hetalia – are down this year, I think we can assume their doujin will not feature Dragon Kid but instead gay dads, which I think is what that show is about according to Tumblr.
By the way, fanfiction (‘SS’ in Japanese and most of ‘FC(小説)’ at Comiket) seems to be very popular with fujoshi (including all my English-speaking friends), but I don’t know a single guy including myself who cares about it at all, even though I’ll happily read all kinds of amateurish comics. I’m sure there’s plenty of counterexamples, though.
In other news TYPE-MOON has almost double the circle count compared to where it’s been for years (presumably due to Fate/Zero), Leaf&Key continue to fade away and Touhou is still the most popular genre out there at 2670.
