Shadow sacrifice, ancestral sacrifice, and ritual ceremony.

Become the protagonist of this "Great Mystery",
From the beginning of the cowardly girl,
Transformed into a senseless killing tool.
When consciousness is opened again,
Who is her host?
And what will be her fate?

Come on, someone is waiting for you
Rushing to this sacrificial ceremony...
