AKB0048 - Season 1 Episode 7 Kirara of Succession

With some of the AKB successors attending a peace ceremony, Kanata, Mimori, Chieri and 76th gen understudy Megumi are chosen to be stand-ins for the next concert. As Chieri's standing in for Yūko invokes jealousy from the 76th gen understudies, they dig up dirt on how her father is a manufacturer of DES weapons. Chieri explains to Nagisa about how she ran away from home when she heard her father's machines were being used by DES. As Kanata chases after Chieri, reminding her that her father should not affect her dream, Minami, Yūko and some other successors who believe Kanata should be made into a successor follow Tsubasa to where she meets Sensei-Sensei. There, they discover a cave full of Kirara, which shows a mirror of who succeeds the original AKB48 member, predicting Kanata will succeed Minami, who does not take it well.
