I am sure many of you have watched Ep. 12 of Lucky Star (Comiket Episode) thru many different mediums. Remember the assignment that Konata assigned to the Hiiragi sisters?
Yes! The routes to the different doujinshi circles and grabbing the doujins.
Apparently, the good people over at Canned Dogs did some research with the data provided and with reference with Comiket 71 (31st December 2006) booths… it shows what circles Legendary Girl A buys from!
Red marks –
イ-46 (Haruhi ero doujin)
キ-01 (both Haruhi ero doujin)
Y-36 (Original male oriented doujinshi)
A-80 (Both eroge artists)
A-50 (Pro manga author, Marimite doujinshi)
Green pen –
イ-30 (rape stuff with Shounen Jump characters)
A-56 (Haruhi ero doujin)
W-49 (Both of them are very extreme circles with stuff that involve cutting people up and weird mutations, one of them had Haruhi stuff)
(Ripped from Canned Dogs. All credits in this post goes to them)
Do check out their post. It contains picture links of some of the doujin circles.
