Demon Slayer Shion is a tense exploration-and-survival RPG that drops you into a sprawling, supernatural cave to uncover the fate of the legendary Demon Slayer Ayano Senjuin and the search party that vanished after her disappearance. You play as Shion Rokujou, a top-class Demon Slayer who ventures alone into the depths, facing grotesque creatures, poisonous environments, and choices that shape multiple possible endings.
