Plenty of Hatsune Miku and K-On! to be seen at the event, same goes for Lucky Star and Macross Frontier as well. Not many Haruhi though. ^^; She would be the choice of many Ita-sha makers one or two years back I believe.
And that makes me wonder, where are all the Ita-sha featuring previously famous anime characters right now? Does the owners change the stickers based on the popularity of the anime from time to time? ^^;
