Keitai ura site (2010)

Natsuko and Takeshi out of curiosity, go to a famous haunted place from TV, but never return. Maki and Eri meet up with Yokomizo and Kobayashi on their way home from school and, thinking the haunted place is just another made for TV urban legend spot, decide to go there. While on their way, the girls joke around about it on Twitter, unaware of the tragedy that was about to befall them.
