Once she gets tired she asks Ayumi to play another game with her: find three things for her and she will tell Ayumi a secret. Once Ayumi finds all three things she finds her inside girls' bathroom. Yuka tells about how she loved her brother and how she hates Naomi, at which point Ayumi realises that the spirit is Yuka. Yuka then says that she'll like to kill her, but Ayumi dodges her attack.
