(Almost) all completed series.
Updated Jan. 08, 2007
Well, I looked up every single series that wasn't blue or green on Manga-Updates - I couldn't find some of them, but I did find the vast majority and compiled a near-complete list of completed series:
*Beloved Teddy Bear
*Blind Point Lake
*Boogiepop Doesn't Laugh
*Chizumi and Fujiomi (it's supposed to have an omake, though)
*Bernie's Drawing Diary is missing chapters 3-6, but according to Manga-Updates, the series is complete.
*Boys N Girl is listed as being complete on Manga-Updates at 5 volumes, but it doesn't list the chapters - has anyone read this, and is it complete?
Hope I didn't miss any. ^_^
