Yami Shibai

Synopsis

While trying to complete a huge amount of unfinished homework, three middle school friends decide to take a break and watch a recorded videotape, which supposedly shows things that the recorder didn't remember shooting. When the video starts playing the friends notice something which resembles a human face next to a gravestone and assume that was the scary footage. However Takaaki also notices a strange humanoid figure in the background, which his friends fail to see, and upon rewinding the tape, finds that the figure somehow moves to the foreground and starts staring directly at him. Now thoroughly spooked, Takaaki notices two more humanoid faces reflecting in the screen and turns around to find that his friends had morphed into strange humanoid creatures who continue to question him about what he had seen.
