Thank you for looking! I am selling these items because I was accepted to my desired school for the 2026 academic year! All pages, with CD. Some writing (about 10% of the book), and some stains on the cover, etc. The back cover of the "Rittai to Tenkaizu" book is slightly torn (see photo 7). There is a lot of writing in pencil, and it is difficult to erase, so I am selling it at a significantly reduced price. Original price: 660 yen per book Please erase the writing with an eraser and make copies to use. Please purchase only if you understand the above conditions and that these are used items.
