■Story

After school on Friday, photography club member Aoki takes Rin and Shinjou to explore an abandoned building. The ruins in Kokkotsu Mountain are rumored to be cursed—a place humans should never approach. However, the three venture in without fear, and the situation quickly spirals out of control. Sudden rain traps them inside, screams erupt, and Shinjou goes missing. Then Rin is kidnapped by a mysterious man. On the PC monitor in the room, they witness Rin being violated by a middle-aged man.
