Both are based on real companies. As a mystery novel, I think "Dozoku Kigyō" (Family-Owned Company) is a masterpiece that keeps you hooked and makes you want to know what happens next. [Please Note] Dozoku Kigyō (Family-Owned Company) The cover and dust jacket are yellowed. There are several creases. Please refer to the images. There is no problem with reading it. There are no tears or writing, but there are signs of wear, yellowing, stains, and fading commensurate with age. This is for those who just want to be able to read it. Please refrain from purchasing if you are sensitive, particular about details, or looking for a pristine item. *Please refer to the profile.*
