⚫︎ Reference price: ¥693 A time-slip mystery. This work was adapted into a drama in 2020, starring Ryoma Takeuchi. The ending is different from the drama, so I highly recommend it to those who haven't read the original. ⚫︎ Only volumes 2, 4, 8, and 10 have obi. There is a small stain on the back of the obi for volume 2 and on the bottom of volume 8 (see photos). There is some yellowing due to aging, but there are no noticeable stains or scratches, and the condition is relatively clean.
