I go to an engineering school. There's only one girl in my class, and I don't have any problem telling anyone I use a Nagahide Niwa siggy. Not that anyone cares.
Do you have such image to otaku?
I don't have any wall scroll or booby mouse pads.
But I think I'm otaku because I like anime and game very much.
I think you're saying just about creepy people. It seems that there is large difference between our images of otaku.
