Muhyo & Roji's Bureau of Supernatural Investigation Complete 18-volume set. I'm moving and selling some of the countless manga I have at home on Mercari. There is some yellowing and staining. I apologize that my checking has been lax due to having too many other works and tasks. There may be unexpected tears or scratches. I will check any concerns you may have. If you're just looking to read it, and are willing to purchase without complaint, please consider it.
