Having failed in her requested exorcism, Rabura is feeling down. Meika has an idea to cheer her up. Meanwhile, a strange scream comes from hermit Ito's room.

On December 29, Yūta is shocked to find Ito dead at the shrine and uses his power to go back in time to earlier that day. After Yūta possesses Rabura and informs her about Ito's impending doom, Mikatan manages to stop her from going to the temple. Ito reveals to Mikatan that the other girls' names in the video were people who bullied her at school, further revealing that she originally posted the video herself as a prank, but someone else edited the video to include her name and sent out threatening e-mails. When Mikatan mentions she was raised with two other kids at Über Labs, Yūta has a flashback of Pine using a power called "Über-fy" to protect Chiyoko. The next day, the Turtle Man captures Muhi as punishment for not showing up at the shrine. Using his powers to manipulate Ito's phone, Yūta lures the intruder up to the rooftop and has Meika and Rabura lay out a trap for him, but he see through their scheme and shoots Meika.

As Kenji and Mikatan arrive on the scene, the Turtle Man reveals he possesses the same Über-fy powers they do and fights back. However, Kenji, who is able to perceive Yūta, creates an opportunity for him to possess Rabura and defeat the intruder, with Meika also surviving. Afterwards, the girls discover the intruder was Ito's homeroom teacher Chihaya Tomoda, who, out of a deranged love for Ito, allowed himself to be possessed by QMay Tsubouchi's spirit in order to carry out revenge against the students who bullied Ito. The next day, the girls hold a New Year's Party, during which Meika reveals that Yūta is biologically female, later telling Ito about how she came to meet Mikatan. After Kenji helps out Mikatan, who needs to take medication to counter the side effects of her powers, the meteorite in orbit suddenly starts hurtling towards Earth. Revealing himself to be Yūta's future self, Kenji gives Yūta the Nandala-Gandala, which is blank except for the word "U-turn", and tells Yūta that in order to regain possession of his body and prevent Earth's destruction, he must go back in time to the point where it all began.

With thirty minutes left on the clock, Guriko infiltrates the Korai House and heavily damages Meika, putting a stop to her hacking. As Yūta faces off against Guriko, Rabura manages to stop Tsubouchi and exorcise him, allowing Ito and Meika to finish the hacking and launch the missiles and destroy the meteor. Meanwhile, Mikatan decides to activate her power to stop Yūta and Guriko fighting. Before Mikatan is killed by the side effects, Yūta switches bodies with her, returning Mikatan back to Chiyoko's body while he passes away in hers. 49 days later, the Spirit Yūta bids farewell to the others before going back in time to accomplish what he needs to do for a bright future.
