Although i'm not exactly sure what book that is, I can tell you its absolutely incredibly rare. I watch suikoden auctions all the time and i've only ever seen that for sale one time. I bid on it but it ended up selling for a crazy amount of something like over 100, 000yen. To this day i'm still wondering what's inside it. In fact this is only the second time ever i've seen it pictured.patapi wrote:I'm able to identify each of the books, but there's one that I'm not familiar with, so hopefully someone here can help.
Here is a picture of the first time I saw it
