It's another hidden Doujin Artbook by the famous Ibara/mushi artist (yeah i really love him).
Seeing this offer for 20e i just had to buy this of course.
My question:

Is there any other artbook/comic/Doujin or whatever by him?
I already have the following:
- Ningen & - Shakkuru
- Official Ibara Illustration Book
- The Artbook from the mushi DVD
- STYLEOS Doujin (from ebay)

I don't like to get those cheesy little guides that come along with a DVD, but am kinda
looking for anything else published by him.
Thanks in advance for any information

I'd be interested in purchasing the Shakkuru or the Ningen by Tomoyuki Kotani. I have not been able to find them yet. I wonder if you could help me. BTW, are you interested in selling any of yours?

This is not for sale but I figured I'd show it off..
