Two important birthdays are coming up, and surprise parties are being planned for both of them! Neither Nephy or Zagan, however, know a thing about how birthdays are supposed to be celebrated, so a disaster is certainly in the works. The entire castle is in a celebratory mood, but dark clouds are looming over the horizon. There’s a terrible problem haunting Nephteros which must be taken care of before any sort of party happens, but Zagan still has no idea how to solve it. What’s more, after a month of relative peace and quiet, Shere Khan and Bifrons are finally making their move. Join Nephy and the ever awkward Zagan for all this and more in volume twelve of An Archdemon’s Dilemma: How to Love Your Elf Bride! Fuminori Teshima is a Japanese author best known for the series An Archdemon's Dilemma: How to Love Your Elf Bride .
