So.....did you find what you needed? I could send you some stuff or tell you a good place to find ref. material but it'd be on the hentai side and I wouldn't want it to be something that'd offend you....

dust speck.........>_<

Hmmm, the longest huh? How about if I answer that with the longest running since a definition like the most chapters (and from what I saw, that's how a lot of people were answering) seems too easy.

I read Garasu no Kamen (Glass Mask) which began in 1976 and is still being written and published to this day.

Oh, and by the way, even though the author, Miuchi Suzue, said she saw the end coming a couple of years ago, there's not one in sight (yet).

DUST SPECK!!?? Holy cow, that's a pretty cold way to welcome a new poster (gotta see if i can find a way to change that, that's pretty darned insulting)
