No One at the Altar -Hysteria- (Prologue to Madness)

Synopsis

“Restore the dead to life.” A true descent into infernal sorcery—a horror novel set on a cursed isolated island, “Naruumi Island.”

Naruumi Island is a small island located far from the Japanese archipelago.

Set in the 1980s. After a certain incident, Reigetsu Toriumi and her sister-in-law Ichiko Toriumi move to Naruumi Island in their aunt’s care for the new year, relocating from the mainland. The two, who had been living in the city, gradually become accustomed to the island’s unique customs and regional characteristics under their aunt Himiko Toriumi’s care, slowly blending in with the islanders.

Then one day, driven by curiosity, Reigetsu and Ichiko venture into a forbidden zone known as District C, an uninhabited area of the island. What they witness there is an inexplicable malevolent spirit. In confronting it, they discover a connection to “Sylvia Faith”—a traditional religion tied to Naruumi Island itself.

The game functions as a visual novel through the middle section, then switches to an adventure-style format in the latter half where players flee through a pitch-black frontier forest, using choices to escape from creatures.
