11화: 카나에와 친구가 쇼핑 플라자 여행 중 반복되는 불편한 작별을 마주하다

11

Kanae and her friend await their train home after a day trip to the country, and decide to visit a nearby shopping plaza to pass the time. En route, they pass by a boy waving goodbye, repeatedly saying "Bye-bye". At the plaza, everyone waves to them, repeating "Bye-bye", which begins to perturb the girls. Kanae is overcome with fatigue, so they find a café, whose customers are waving goodbye through the window. Kanae feels like she is being forcibly possessed by an unknown force, and her friend tries in vain to call for help. Suddenly, they're surrounded by a crowd, and Kanae faints. Her friend confronts someone in the crowd, demanding answers, but is merely told to say goodbye. She entreats Kanae to escape, but Kanae is now fully possessed, and the entity bids Kanae goodbye... Suddenly, the friend awakens in a hospital; a doctor explains that she and Kanae were found unconscious. She remembers the events in the plaza, but the doctor explains that the townspeople brought them to the hospital, and that she may have been hallucinating from the heat. She vehemently denies this, before the doctor begins repeating "Bye-bye"... (Source: Wikipedia)
