In keeping with the tradition established by this pool I'm uploading the two side-story book cover page posts uploaded in the past year. I'll also position them in the pool relative to their upload date on pixiv.

This two-for-one deal appears to be a FANBOX exclusive, but the covers don't have the interpunct (・) that the other posts in the FANBOX-exclusive parallel series does, so I'm not sure which of the two main series they're side-stories of. (If they release a new art book, that might answer that question. The art books number the side-story books and have their release dates as well.) If I'm (machine-)translating the description right, people who saw the FANBOX post before Christmas 2023 were able to download a work-in-progress version. I don't have a FANBOX subscription to Rakugaki-Biyori yet, though I'd like to eventually. I can say these covers don't match any of the previous side-story comic covers (though there are currently two that are inaccessible).
