Monday of Upheaval I.Hibiki, Daichi and Io are arrested by the JP's and brought to a secret underground base located at the National Diet Building. Here, Commander Makoto Sako, explains to Hibiki that the JP's protects Japan from "paranormal anomalies" before she introduces the JP's Chief, Yamato Hotsuin who says that Hibiki's demon, the avatar Byakko is unique, being one of the four symbols of the Chinese constellations. Furthermore, he explains that the Dubhe was only one of 7 creatures called the Septentriones, each of which will appear in the next six days and should the JP's fail to defeat them then the world will disappear. As the JP's scientists begin to analyze the demon summoning app, Hibiki ponders on Yamato's words. The following day, Makoto releases them by taking them to an emergency shelter in Chūō. Here, it is discovered that a rumor of demons running amok is spreading. As Hikibi looks around at all of the refugees in a church, a winged-demon attacks and Hibiki summons Byakko to protect them. As Hibiki fights an endless swarm of the demons, Makoto shows up with her demon, Power and helps Hibiki defeat the winged-demons by destroying the rogue cellphone which had been summoning them. In the aftermath Hibiki walks away when he realizes the refugees are afraid of him, but gains resolve, along with Daichi and Io to help the JP's after a child thanks him for protecting them. Back at the Diet Building, Yamato outlines Hibiki, Daichi and Io's first mission: to locate and rescue missing JP's scientist Dr. Fumi Kanno.
