Our take on Novena Diabolos

The defining structure is a nine-day investigation that changes its locations, clues, culprits, and character identities on each playthrough.

What is Novena Diabolos?

Novena Diabolos is an occult survival mystery adventure set in Hope Hill Village.

A reporter with no memory must investigate supernatural murders, explore the village, speak with its inhabitants, and uncover how to escape. The reporter has nine days to survive while trying to save a human girl held among four hostile demonesses and earn her trust. Each playthrough changes the available locations, clues, and culprits. The identity of the human girl and the demonesses pursuing the reporter are also selected differently each time. The game presents its investigation through a visual-novel structure with environmental exploration, conversations, crime-solving, and information about supernatural rituals and the occult.
