There are several Japanese publications related to 3x3 Eyes available in addition to the manga. Books for other series created by Yuzo Takada, such as Blue Seed, are not listed here. This was the first collection of Yuzo Takada's artwork to be published. It contains artwork from 3x3 Eyes and earlier series such as Everyday is Sunday. It does not include art from Blue Seed or Almighty Cultural Cat-Girl.
All text is printed in both Japanese and English, and the comments are very informative.
The first volume is a hardcover, 96-page artbook containing most of the artwork, with a heavy emphasis on 3x3 Eyes. It is similar to the format of AiEN KiEN, but unfortunately the coments are not bilingual. The second book is a softcover, 32-page poster collection. Both books are housed in a clear plastic slipcover. 3x3 Eyes fans may have.
