Honestly, I feel like people get too hung up on the 'supernatural' label when talking about 'Way of the Devil'. It's not your typical ghosts-and-goblins setup. The core of it is this oppressive, almost sentient, system of 'Rules' and 'Abnormalities' that pervade everything. It's less about a monster under the bed and more about the fundamental laws of reality being hostile and predatory. Characters don't just fight demons; they navigate and exploit these cosmic glitches, often using their own contaminated bodies as tools. The horror comes from the realization that the world itself is the antagonist, and survival means becoming part of its malfunction.
What really stuck with me were the 'Devils'. They aren't independent beings but manifestations of concepts, emotions, or events—like a 'Drowned Ghost' representing collective drowning trauma. They're bound by their own bizarre, tragic logic, and defeating them is more about solving a ritualistic puzzle than winning a brawl. The whole cultivation system is also deeply unnatural, involving mutilation, possession, and bargaining with these entities for power. It's a bleak, mechanistic kind of supernatural where everything has a price, and the human element is constantly being eroded.
