S01E05 A Ghost Appeared

Halkara has established a new Nutri-Spirit factory in a nearby town, making frequent trips from her highland cottage, but she returns home drained each night. Whispers of a ghost haunting the factory have circulated, leaving her to handle everything on her own as the locals are too frightened to help. Although Azusa isn't good with ghosts, she can't stand to see Halkara overworked, so she calls on Beelzebub for assistance and sets off to the factory under the cover of night.
