The last part in this series. Once again I couldn't find anything on this title, so I don't know what it's about. Marukomu, who uploaded this at ADC says that from what he can determine it's about a young girl getting a part-time job in the hot spring and ends up having to fill in for one of the prostitutes. This one has less boobies than all the previous installments, but a lot of sillyness. Enjoy!
