Ep. 12: Yuuta acepta su lado chuunibyou y ayuda a Rikka a despedirse de su padre en el Horizonte Etéreo.

12

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