I know this probably isn't the place to ask, but I'll try just in case someone knows.

I'm gonna be in Tokyo this fall, is there any place (like, say, in akiba) that'll be selling C80 doujins, or is it pretty much a "C80 only" type thing?

There are some merry nightmare doujins I'm desperate to get my hands on, and I think my only hope is to find them when I'm actually in Tokyo for a week.
