REGNATURI : Crescent Ancientus

A war was waving in an unknown land, far from the eyes of the mortals ---- until a door opens.

Aria lives a normal life with her twin sister, until she met Levine. Strange it is, she discovers he is a vampire, and she's cool with it.

As Levine becomes part of her life's system, she opens more door for people to come in, more close boxes to open, and it has just begun: she opened a door that people around her tries not for her to open.

Was Aria bound to know the truth and win this war?
