Except for the following points, I don't remember anything else about the manga. #1. The ghost hunters were men iirc and they kept some sort of ghost-eating demon at their office. The demon had the appearance of a cute little girl. #2. I remember a chapter where they had a friendly ghost over at the office and the demon accidentally ate the girl ghost. But the ghost-eating demon spat out the ghost afterward when the guys told her to do so. #3. There were other ghost-eating demons in the manga and I remember there was one chapter where another ghost-eating demon girl appeared and, together, the two ghost-eating demon girls went on some sort of buffet. An all you can eat ghost buffet. The demon girls were armed with fork and spoon, like they were really going for dinner. Anyone knows the title?
