Slime Taoshite 300-nen, Shiranai Uchi ni Level Max ni Nattemashita Temporada 1 Episódio 5

Halkara has built a new Nutri-Spirit factory in a nearby town and is now regularly going there from the cottage in the highlands, but she comes home exhausted every evening. It seems rumors have spread saying theres a ghost showing up at the factory, so shes had to do all the work alone since all the locals are scared to go there. Azusa doesnt deal well with ghosts at all, but she cant bear to let Halkara work herself to exhaustion, so she summons Beelzebub to help and heads to the factory late at night.
