As Yuta worries about having not seen Rikka in a while, Sanae ends up discarding her other persona whilst Kumin starts impersonating Rikka. Later that night, Yuta learns that Rikka has moved in with her mother and grandparents. As Yuta 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 chunibyo syndrome and start her own. Arriving before Rikka, Yuta finally accepts both her and his own chunibyo side, taking her to the 'Ethereal Horizon', giving Rikka the opportunity to properly say goodbye to her father. Rikka soon resumes her chunibyo play, despite Yūta still finding it a little embarrassing.
