In the case of Yuki Aihara.
Tokuoka and Mai are on their way to meet with Yuki (known to The World as Yukichin), who is in Yokohama. Tokuoka gets stuck in traffic, and Mai goes to the library in Tokyo to attempt to look up information. During this time, she hears the sound. Meanwhile, Yuki is watching a movie when suddenly THE WORLD flashes on the screen, the power goes out, and the employees attempt to evacuate the building. Yuki runs into an unnamed woman who works at the building, and the two try to find their way out while the crowd gets stuck on the broken escalators. The two eventually resort to climbing through a ventilation shaft to a hallway with an elevator. After the fire alarm activates and starts sending out carbon dioxide, the woman rips off her shirt sleeves and makes mittens for both of them to slide down the elevator cables. At the same time, Tokuoka is finding his way to the meeting point without his car, as it's still trapped in gridlock, and Mai is using an old offline newspaper reel to look up information. She comes across Harald Hoerwick (the creator of The World), and the Epitaph of Twilight. Later, she contacts Kyo, and finds out that fires have broken out all over Yokohama, and that there is no cell phone service there either. Yuki and the woman find themselves at the bottom of the shaft, and it seems that the woman has twisted her ankle. They make their way onto the first floor regardless, and discover upon exiting the building that many cars have crashed. The woman says that it is the second coming of Pluto's Kiss. Finally, at 9:00, six hours after Tokuoka said that he would meet Yuki, he arrives to find Yuki waiting for him. Mai finally gets through to Tokuoka, and Kyo gets through to Yuki, and it is discovered that Kyo knows quite a bit about the Epitaph of Twilight.
