I Want to Be a Receptionist in This Magical World, Vol. 7 (manga)

An ominous gloom hangs over the continent given the continued rise in demon activity and a recent unnerving discovery… But, despite it all, the nations gather in Doran to kick off Walhelnus, and few are as excited as Nunnally. To her, Walhelnus means that igneous imbecile, Rockmann, will be too busy competing to bother her for a few blissful days while she works the counter. Well, they would have been blissful if she didn't find herself sucked into the middle of a magical duel! It's Harré vs. Doran's knights, fire vs. ice, in the battle everyone's been waiting for and the rematch Nunnally's been dreaming of.

Volume 7 of the I Want to Be a Receptionist in This Magical World manga series by Jan Cash.
