Thank you for viewing. I am selling these items because I was accepted to my desired school for the 2026 academic year. All pages are present. There is dirt on the cover, pencil eraser marks, and circled answers in the answer section (see photo 4). It should be fine if you copy the pages for use. Please purchase only if you understand that these are used items. Hitotorikun Series 21, 22, 23, 40, 42, 61, 87, 89, 92 660 yen per book
