In the terms of the Gregory Horror Show, Nights are used to stand for chapters or segments of the story. Each night will introduce three or more guests. The player must take their souls and give them to death in order to proceed to the next night.
In the anime, the individual episodes are called Nights except for in The Bloody Karte, where they're called Cases.
Each of the six chapters of Soul Collector are known as Nights.
