"This story will not end in vain," Maame Kozumi vowed. 

 
After four years of walking this path, she finally arrives in a certain "city."

This place seems familiar, yet she can’t recall anything about it. 
This is the "Lost City," a forgotten town deep in the ocean. 

 
"Please, remember that music—"

 
And so begins her journey to recover lost memories and music.
