The Kantoku Calendar 2013 arrived on the same day as the Shana stuff but I don’t have a scanner or anything (it’s also really big). I’m hesitant to actually take it out of the packaging because I don’t want to damage the pretty pictures :(
The art is gorgeous (it is Kantoku after all) but I haven’t found any scans aside from this pool: https://yande.re/pool/show/2913 (only has 3 pages)
