Beautiful condition with first edition obi for all volumes. [Oshi no Ko] Complete set of 18 volumes: all 16 volumes of the main series + spin-off novels "Hoshi no Ko no Spica" and "Futari no Etude". This is a set of the hit series by Aka Akasaka and Mengo Yokoyari, which has been adapted into anime, drama, and film, with first edition obi! I purchased all volumes new and have only read them once, so I believe the condition of the items is also good.
