I Want to Be a Receptionist in This Magical World, Vol. 6 (manga)

Be it across an ocean or just across town, Nunnally seems cursed to find Rockmann wherever she goes… What starts as a night out with Nikke and Benjamine going undercover as barmaids to snoop on Satanás's gallivanting quickly goes off the rails when Rockmann and the knights arrive instead! Then preparations for the upcoming Walhelnus tournament put her and Rockmann on yet another collision course. When an accident forces fire and ice closer than they've ever been before, the result isn't steam…but sparks?
