The visual novel is set in a dystopian alternate reality in which most nations are ruled by unelected bureaucrats while the government’s political power is extremely limited. In particular, the game takes place in Santa Rita, a city suffocated by corruption and ruled by the mob.
You play as Luna, a young woman with a murky past whose life is turned upside down when her father dies and she discovers her old man was engaged in some very shady business. Even worse, Luna finds out that her father has made a lot of enemies over the years. Those people seem to hold a deep grudge against her father...and against his family in general.
They want payback. They want blood. Her blood.
Aided by the mysterious Mr. Cavalcanti, a friend of her father, Luna leaves Santa Rita, her hometown – she flees her home to save her life.
