Boogiepop and Others

One day after school, Kinoshita Kyouko asks Suema Kazuko to walk home with her. As they're walking along the river going home, Kyouko asks Kazuko if she knows another way home. Kazuko teases her, asking her if she thinks someone's going to kill her. Kyouko stays silent and Kazuko tells her she's overthinking things, when suddenly Kirima Nagi appears before them. Nagi then pins Kyouko to the ground.
