Does anyone know where to get Karin(Chibi Vampire)? I've been looking but I haven't found any websites that carry it anymore.
Try by mIRC program : http://gotlurk.net
The #lurk channel has all mangas ever scanlated, if they don't have something, no one has.
and try to search for newest releases with http://www.mangaupdates.com/
For direct download, there is in http://www.mangadownload.net/index.php?a=private but to get to private section, you need to post in their forum or donate.
Edit : if you need anime, http://animestash.info/db/
