The Shaman King Fan Book was released after Volume 32. It contained detialed character profiles, Q&A, chapter summeries, fan art, fan questions, and more Shaman King goodness. It does contain some minor spoilers.
Below is a link to the RAW scans from parts of the book. Not all the pages are in there. The scans are in HQ format. Most of .jpg and only a few .png. Please view the Read me.txt file. It is coded in UNICODE so, you may have an error viewing it.
Those are the only scans I can get a hold of. If you want more, then buy the book for yourself!
Well, that ate up a bunch of my time. Put a little dent in my Butsu Zone chapter releases, oh well. This will hold you over if you are waiting for my next release.
