One day, after finishing his work, Master Shimabuku fell asleep outside on the cover of the well out back. He began to dream. In his dream, a man came to his dojo and challenged him to a fight. Shimabuku declined. He held one hand up as a sign of peace while the other hand was formed into a fist in preparedness. He told the man that he was a gentleman and only fought if necessary. The man suddenly set a ring of fire around Shimabuku. As the fire drew closer, Shimabuku drew water from the well and put the fire out. Following this dream, Shimabuku saw a picture of a water goddess, Mizu Gami. She had her hands formed the same as his were in his dream. He immediately adopted Mizu Gami, also known as Me-gami and Goshugin Sama, as the protecting goddess of Isshinryu.
