This is a complete set of all 13 volumes of "Gokudo" by Takayuki Yamaguchi, published by Champion Comics. I purchased these used books about 4 years ago. There is some yellowing on the edges of the books due to aging, but otherwise, there are no major stains or tears on the covers or in the text. The books have been stored out of direct sunlight. Please understand that these are used books before purchasing.
