★Kenkyaku Shobai by Shotaro Ikenami, published by Shinchosha Bunko (Complete set of 16 volumes + 3 extra volumes, 19 books total). These books are in beautiful condition, as shown in the images, as they have only been read once. They have been stored on a bookshelf where they wouldn't gather dust, so I believe they are in good condition. Please consider them as used books, as they have been read once and stored at home. ○ Kenkyaku Shobai, Complete 16 volumes (New Edition) ○ Kenkyaku Shobai, Extra Volumes: Kuroshiro (Part 1, Part 2), Naisho Naisho, all 3 volumes
