About the game
We Know the Devil is a visual novel following a group of teenagers who, without much enthusiasm, end up confronting the devil during summer camp. It centers on sharp-tongued Neptune, tomboyish Jupiter, and timid Venus as they gradually open up to one another, though one of them always ends up on the outside. Pillow Fight and Worst Girls Games co-developed the title, with Pillow Fight also publishing it in 2016.
