In a flashback, a boy named Pine asks a girl named Guriko to run away from a laboratory with him, while another girl, Chiyoko, sings a song. In present time, as Rabura prepares for a date with a man named Gliese, Yūta discovers that a girl included on a list of names posted by QMay has been found dead, with Ito's name also featured on that list. Yūta manages to use cinnamon power to possess Rabura's body, but fails to warn the others about the trouble Ito is in before its effects run out. After meeting with Rabura, Gliese reveals he is from the NSA, and is trying to contact Meika so she can hack the Qmay group's virus before it can disrupt a satellite meant to intercept the meteor. They are interrupted by Kenji, who is thwarted by Rabura, before all the girls end up getting into a fight. Later, Yūta recognizes a song that Mikatan sings as the one Chiyoko sang.

After getting her medication, Yūta reveals his identity as Pine to Mikatan, who is revealed to be Chiyoko's soul inhabiting Giroko's body. Mikatan explains how, after she ended up switching bodies, she was looked after by Ishigata, the man who helped everyone escape from Über Labs, who was later killed by lab members searching for her. The next day, Yūta speaks with various scientists, who contradict Gliese's claims about being able to destroy the meteor with nuclear weapons, leading him to suspect Gliese is lying about his identity. Afterwards, Yūta speaks with Meika about Mikatan's worsening condition, asking her to do a physical check-up on her. The next day, December 27, Chiranosuke urges Yūta not to change the days events that would lead to the group fighting and making up with each other, but he decides against it and confronts Gliese Gliese reveals himself to be one of the leaders of the Qmay group who devised a scheme to to use Rabura to coerce Meika into hacking into a satellite to change the meteor's trajectory towards Earth. Hitting Yūta with an anesthetic, Gliese attacks using Über-fy powers, revealing himself to be Guriko, the one now possessing Pine's body.
