This is the Tamiou series by Jun Ikeido. Tamiou Tamiou: Siberia's Conspiracy This is a set of two books. Tamiou is a paperback, and Tamiou: Siberia's Conspiracy is a hardcover. I have read them several times. The contents are readable without any problems, but there are scratches and minor imperfections on the covers, as well as damage to the dust jackets.
