As the masked man rushes towards her Yuri starts to panic and grabs hold of the bridge. While crossing the bridge she notices the masked man not following and proceeds to ask if he knows about anything about the world they're in. On the bridge she thinks about meeting up with her brother. Suddenly attacked from behind, Yuri drops her phone and heads for a suspension bridge near her. When he finishes explaining things to her they agree to meet up. Attempting to phone her brother, the call connects, and she immediately asks for his help. Pulling out her phone, she attempts to contact her parents but isn't able to get through. On the roof top, she realizes she's not in Tokyo. Looking into the hall way she sees the masked man following and heads upwards. Upon running away, she finds a stairway and notices a warning sign.
