Volume 14 of Kamisama Kiss came out yesterday, just a month after volume 13. (I guess they did this because the TV anime is being aired now?)
If you bought the tankobon at the Yurindo bookstore chain, the tankobon came with a postcard:
The text says “Thank you for buying Kamisama Kiss 14 at Yurindo”.
A Yokohama Yurindo branch is displaying 24 b&w manuscripts from chapter 78 (the last chapter in volume 13), so I went there to get the tankobon and to look at the manuscripts. When I see the actual manuscripts, I always wish I could read the manga in that size so I could pore over the details.
