Darkness has been buried for thousands of years
History is also submerged in the river of time
What are the unknown truths of the past?
When human civilization has developed faults,
The wheel of fortune, which had been silent for a long time, woke her up after sleeping for thousands of years...
The mysterious girl with the inheritance of ancient thousand-year civilization,
Wandering in this extremely strange "artificial human era",
What mission does she bear?
Where will fate push her?
