This is a set of two books. Both contain bonus chapters of Jujutsu Kaisen that are not included in the main volumes. Please be aware that there may be discrepancies in my understanding, so please research and confirm before purchasing. The 2021.2 edition has a folded page from the cover (see photo 2). I have priced these items higher because I have kept them with care. I am selling them to declutter. I am also listing these on other sites, so there is a possibility that I may suddenly delete the listing or cancel the sale.
