Prisoner Riku, all 38 volumes - Series Name: Prisoner Riku - Volumes: Complete set (Volumes 1-38) - Publisher: Akita Shoten This is a complete set I purchased on Mercari. I'm selling it now that I've finished reading it. There is some soiling, but there were no problems with reading them. They are likely ex-rental copies, as all volumes have plastic covers. I will not sell individual volumes, as this is a complete set. Please understand that these are used books. Thank you for looking.
