Roreil is highly subservient towards Nureha, telling off Mizufa for calling Adventurers "greedy" because Nureha had given them the iron-steel train. After Nureha runs off and her whereabouts are unknown, Roreil goes into a bit of a frenzy looking for her, demanding them to stop the operation in favor of finding her. He finds her in the Town of Saphir, which was being ransacked in the chaos caused by Operation Red Night. When he pleads with her to return to safety, she instead tells him to eliminate all the wyverns and Nightshades, and decides to cancel Mizufa's operation. Although he hesitates for a second, she reasserts her authority, and he quickly goes to obey her commands.
