Mira tells her new friends about her promise to a "boy" along time ago to find an asteroid and immediately discovers that Manaka is in fact Ao Manaka, the "boy" she met back at that camp, having mistakenly assumed she was a boy due to her short hair and name. The two had remembered each other throughout the years.
