An Archdemon's Dilemma, How to Love Your Elf Bride, Volume 8

Zagan searches for the whereabouts of his old friend Marc as the town livens due to a festival called Alshiere Imera. Apparently this festival bears the tradition of giving presents to those dear to you. Zagan and Barbatos have a late start on the festival and mill about in confusion. Stella and Alshiera are completely carefree and are here to play. And for some reason, Kuroka is now a cat? It seems another Archdemon is somehow involved and is hot on her tails!
