This artist seems to have deleted all of her works not related to Nettaigyo from Pixiv, Twitter and her blog. Though there's still a list of her old doujins on the blog, there aren't any pictures or summaries or whatnot, just links: http://93choco.net/work/
Not sure why - maybe it's because she was starting her new series and wanted a "clean slate"? Or because she was annoyed by people reposting it to other websites - there's a short message on her Pixiv profile about that. Either way, it's pretty disappointing, seeing as she made so much yuri in the past.
