As Aquors try to figure out how to improve their idol ranking, Yoshiko Tsushima, who had been absent from school for a while, is struggling to put her chūnibyō habits of pretending she is a "fallen angel" behind her. Watching one of Yoshiko's videos as her persona, "Yohane", Chika decides to invite Yoshiko to join Aquors and have everyone act like fallen angels to increase their appeal. Although this identity gives them a boost in rankings, Dia promptly reminds them that it is only a temporary gain, leading Yoshiko to blame herself. Believing Yoshiko truly loves her persona, Chika once again extends her invitation to join Aquors, encouraging her to love herself for who she is. (thetvdb.com)
