The Kasuga-Sama are spirits who come to the Bathhouse in groups by ferry. They wear strange masks and Sokutai (Traditional clothes worn by Japanese nobility), but their bodies are like shadows.
- Kasuga is the name of a famous Shinto Shrine in Japan. There is a traditional ritual dance called "Ama" at Kasuga Shrine, in which dancers wear paper masks called "Zoumen." The mask looks like the one Kasuga-Sama is wearing.
