Dr. STONE SenGen SenGe Ishigami Senku x Asagiri Gen Doujinshi All ages This is a set of two books. I am not considering selling them separately. I am selling these doujinshi because I don't want to keep them, but they were very moving, with stories that covered the final chapter. These are priced as such because I purchased them individually from a new goods通販 (online store). Available for immediate purchase.
