I just received this gem in the mail today. I thought I'd never get to see it, and it was one of a few doujinshi of Okuu that I missed out on but really wanted badly. After speaking with the artist on Pixiv if I could somehow obtain it, he was kind enough to bring me a reserved copy to C85 with him even though it was out of print, and a helpful anon retrieved it for me. Hope you like it.
On a different note, I unfortunately won't be scanning or editing nearly as many books of her as before for several reasons. The main reason being that I have switched my focus from scanning/editing to practice drawing Okuu myself every day and getting help from various Pixiv artists on Twitter/Skype for the past half year. I am very happy with my progress to say the least. I don't post that often unless it's to speak with various artists, but if you'd like to see what I've been up to in regards to Okuu or whatever, here's my twitter and Pixiv ID. That would probably be the best places to contact me through.
