Danger! -Revenge, Dark Site- The Sister-Killer is Among These 3 Bitches

Story

A ruin looming on the former site of an isolation ward. Inside that building, three girls in school uniforms lie sprawled, their limbs bound. The mastermind, 'Ryo Tezuka,' looks down at the girls. Ryo, wearing a hateful expression, recalls the events of a few weeks ago. A sudden call from his father. It was the shocking news that 'your little sister has committed suicide.' As if to mock Ryo, crushed by grief, his family home burns completely down due to a fire from an act of arson. Even his father meets tragedy and passes away. Grief-stricken, Ryo lives a life like a walking corpse. One day, when he casually plays back a video camera he had brought home as a keepsake, it had filmed the cause that drove his sister to suicide. Shaking his head as if to cast off the memory, Ryo once again looks down at the girls sprawled on the floor. They all apparently had some connection to his sister's suicide. While pretending to grieve his sister's death, the three girls desperately deny their involvement. Ryo's face transforms, moment by moment, into that of a vengeful demon. A torture room prepared for the women. In the room, along with torture instruments the likes of which he'd never seen, countless video cameras are installed. "I intend to broadcast your interrogation over the net, all of it, through the cameras... Just flaunt those bodies you're so proud of... Yes, expose your true natures—body and soul!!" You murderers of my sister... you can see them, can't you—the countless bloodshot eyes, starved for female flesh, peering from deep within the net...
