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.
