If you'd like 6 short stories, I can include them for an additional 5000 yen. If you'd like the cover for volume 30, I can include it for an additional 3000 yen. I can also include an art book if you'd like. I bought these and then left them as they were. There is some yellowing due to aging, so please understand this before purchasing. I bought them when they came out and read them once, but I haven't handled them much.
