Last Mamelove gallery is missing around 200~ pictures as of today. In addition, it seems the artist changed his name to オペ子 and closed his Pixiv account. I failed to grab a few images before this happened.
His new pages: http://www3.atpaint.jp/bomaye/index.htm http://bomaye3.blog.fc2.com/
I was in the process of resaving a bunch of images when he suddenly shuttered his Pixiv account, so there are probably duplicates. Apologies!
