Ekaya managed to defeat Murasamemaru with the sword, but before he died, he cursed the village. Nowadays, no one believes in this legend, and the local population using the legend and the color of the village, upon visiting which, it seems that he fell in the Edo period, turned it into an attraction for tourists.
