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.
