Detective School Q 6-disc DVD set. 5 main discs + 1 bonus disc. I watched them all once and then stored them at home. Please note that there are some stains and dirt on the box containing the DVDs. This is Hey! Say! JUMP's Ryosuke Yamada's first drama. It also includes the special drama from his junior days, so please check it out. If you have any questions, feel free to comment.
