Momo, Okarun, and Jiji head to Jiji's house in rural Byakuja Village to investigate the supposed curse hanging over the house. The trio is soon confronted by the eerie Kito Family, the landlords for most of the village. Momo is attacked at the local hot spring while the Kitos question Okarun and Jiji. An all-out fight reveals a hidden, cursed room within Jiji's home and the underground domain of the area's ancient god.
