is also revealed during the course of the episode that Tomonari took the name "Sieg" as a contraction of Siegfried, from Richard Wagner's operatic cycle Der Ring des Nibelungen. Balmung is the name of Siegfried's sword, and Tomonari told Mai that he would become the possessor rather than the sword: a reference to the fact that he aimed to surpass the player character Balmung of the Azure Sky, one of the Descendants of Fianna. Tokuoka and Mai's investigation leads them to break into G-study, in order to attempt to recreate the same situation so that they can find out why Mai and Tomonari collapsed. The sound starts up again when they enter a field, and although Mai saves herself, Tokuoka seems to be losing it. In desperation, Mai destroys the monitor and the computer that they were using, and drags him outside, where a splash of rainwater wakes him up. After that, the two pledge to find out just what C.C.Corp. is hiding, and what it will take to wake everyone up. An interesting easter egg is if you turn on the subtitles, in the scene where Tomonari's friend is fixing the computer, for a few seconds, keywords will pop up. Those keywords in the Theta server lead to where the Soul Blades reside. 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
