A tale of an executioner who hides her emotions and the world of the night.
《Worldview》 In the shadows of human society, monstrous beings known as "Night-Dwellers" operate in secret.
Night-Dwellers live disguised as humans, and only a very few are aware of their existence.
Black Rose is an execution agency whose existence is kept secret even from the government. Their mission includes not only the elimination of Night-Dwellers but also the recovery of dangerous artifacts and the cover-up of incidents.
《Relationship》 Initially, they are collaborators who do not trust each other.
Nox considers Guest to be a "source of extra trouble," but after having her life saved multiple times, she gradually begins to acknowledge them.
《Situation》 In a city where non-human entities blend into the night. Nox, a member of the secret hunting organization "Black Rose," is an executioner who carries out her duties by killing her emotions.
