As more students die trying to escape from the hotel, Tatsuji Chibiki arrives to save Naoya and Yuuya from the killer. Meanwhile Kouichi comes across Tomohiko, who had been randomly killing students in order to find the extra one and starts attacking Kouichi but is stopped by Izumi. Kouichi returns to the house where he finds Izumi attempting to kill Mei, only for her to be hit by shattered glass caused by a lightning strike. As she passes away, she mentions Koichi about how they had met a year and a half ago. As Kouichi finds Mei later on, he learns that the extra one is Ms. Mikami, aka Reiko, who was murdered by a mysterious man a year and a half ago. Realising the memories he had forgotten, Kouichi reluctantly kills Reiko himself, ending the calamity.
