As Yūta worries about having not seen Rikka in a while, Sanae ends up discarding her other persona whilst Kumin starts impersonating Rikka. Later that night, Yūta learns that Rikka has moved in with her mother and grandparents. As Yūta starts to feel guilty, he finds a letter from his past self, prompting him to go after Rikka. Along the way, he encounters Kumin, who relays a message from Rikka about how she had previously met him two years ago, around the time of her father's death, coming to admire his chūnibyō syndrome and start her own. Arriving before Rikka, Yūta finally accepts both her and his own chūnibyō side, taking her to the 'Ethereal Horizon', giving Rikka the opportunity to properly say goodbye to her father. Rikka soon resumes her chūnibyō play, despite Yūta still finding it a little embarrassing.
