These are items I collected by going around used bookstores. I have finished reading them, so I am putting them up for sale. ⚠️ Volumes 38-40 are the new edition. I mistakenly bought two copies of volume 40. Since I bought everything cheaply at used bookstores, all volumes have price reduction stickers, sticker removal marks, age-related deterioration, scratches, etc. Some covers have creases. I have read all the volumes once, but I read them quickly, so there may be oversights such as graffiti. There were no problems with reading them normally. These are used items, so I recommend them to those who don't mind.
