Volumes 1-7 plus a paid bonus storage box, and volumes 8, the lower volume, and 12. Everything in the photos is included. Volume 8 has a Melonbooks paid bonus foil-stamped book cover on it. Underneath, there is the regular volume 8 cover. Other bonuses for volume 8 are not included. I purchased everything new, so I think they are in good condition, but if you are overly concerned about condition, especially the storage box, which is made of thin paper, please understand that there may be some damage before purchasing. I will ship them in a cardboard box. Immediate purchase is OK. No price reduction. No individual sales. (Added) I found volume 11, so I will add it.
