In a village named Takachiho in Tsukusu, far west of Jipang, a people called the "Fire Clan" lived quietly. A young boy named Namida washed ashore on the beach of the village. Ichiyo, a resident of Takachiho village, rescued him. The two grew up as brother and sister. Several years later, Ichiyo is asked to dance a kagura dance at a Takachiho village fête. This was the beginning of a great catastrophe that plunged Jipang into crisis.
