In the long river of time, all people and things are as small as gravel.
Time has silenced the gods, time has made the superstars fall, and time has buried their legends.
But time cannot break their bond.
People? God? Soul?
One day, in the singing of bards, the legend will be revived again.
That year, under the starry sky, they formed a bond.
The young figure responded to the moonlight, with smiles in his eyes, and they said——
"We are brothers who have been together since the age of mythology."
In fact, this is the story of a girl who dressed as Saga and traveled to the era of the first generation of Golden Saints after completing the plot, and began his legendary (ku) and strange (bi) life.
