I Want to Be a Receptionist in This Magical World, Vol. 4 (manga)

Nunnally has arrived at Soreyu! The recent disappearance of ice witches, as well as increased demon sightings, means the southern branch is up to their ears in requests. Working closely with the first division (and Rockmann), Nunnally and the others probe deeper into these mysteries. However, the frigid tone Nunnally once took with Rockmann seems to be warming? Meanwhile, the Festival of Flowers draws near, and Nunnally has been invited by her new coworker, Yakkurin. Have the seeds of love finally begun to bloom for the young receptionist?
