Although the page inside says C84, this was definitely released during C85. Unfortunately, only half of the book is actually by 23. You can find an archive download here:

This guy is pretty popular on image boards. Good to see his first book released.

HNTI, it's actually not his first, but it's understandable you'd think that, as his other work has never shown up. He's mentioned participating in doujinshi before. This is just the first time anyone's ever scanned one. Ridiculously hard to get a hold of. This one was on a restricted 24 hour auction on Yahoo Japan. I never would have found it had I not happened to be looking on that exact day. Not to mention the price...

This is the best thing released out of C85 so far IMO. 23 is one of my favorite artists. Absolutely amazing.
