Publisher: Kodansha (March 1, 2005) Condition: There is a fluorescent line on two pages of the text, and the cover has scratches and wear, indicating use, but I think it is readable. Also, although I have checked it thoroughly, please understand that if there are any overlooked scratches, stains, lines, etc., as it is a used item.
