on her mother, who lives outside Tokyo. The second plotline follows Ryosuke Kawashima, a university economics student who has recently signed up to a new internet service provider. His computer accesses a website by itself, showing him disturbing images of people alone in dark rooms exhibiting bizarre behavior. That night, Ryosuke wakes up to find his computer on again with the disturbing images displaying and frantically unplugs it. The next day he goes to the university computer lab looking for answers and meets Harue Karasawa (Koyuki), a post-graduate computer science student, who suggests he either bookmark the page or screen capture the images for her to examine. Ryosuke attempts to do so, but finds that his computer will not follow his commands. Instead, a video plays of a man with his head in a plastic bag sitting in a room with the words "HELP ME" written all over the walls. A graduate student who Harue is working with explains to Ryosuke his theory that the souls of the dead have begun to invade the physical world. Harue confides her lifelong feelings of isolation to Ryosuke, then begins acting strangely, suggesting that ghosts would want to trap humans in their own loneliness rather than kill them. Ryosuke tries to escape with her to a faraway place on the train. However, their train stops, and Harue, seized by a desire to return home, runs away. Upon returning to her apartment, she witnesses the man with the plastic bag shoot himself on her computer. Harue then presses the "enter" key and sees a video of herself in the present moment on the screen. As she embraces the invisible figure watching her, Harue happily says that she is "not alone". When Ryosuke makes it to her apartment, she has vanished, leaving behind a black ash-like residue on the wall. As people begin vanishing in great numbers, evacuations of Tokyo begin, and a full-scale invasion of the Kanto region by the ghosts is underway. Ryosuke meets Michi in her broken-down car, and after helping her repair it, she goes with him to search for Harue. They find Harue in an abandoned factory, where she shoots herself. When Ryosuke and Michi's car runs out of gas, Ryosuke enters the warehouse to search for fuel, carrying a gas can with him. While searching the warehouse, he accidentally drops the can’s cap, which rolls through the open doorway
