This is one year's worth of issues, from the April 2021 issue to the March 2022 issue. There's a little bit of writing in it, but I think it's mostly blank. I apologize if I missed anything. It's organized in an easy-to-understand way, so you can learn just by looking at the text. There are some folds and scratches. Regular price: 550 yen per book (6,600 yen for 12 books)
