The episode began with Taichi and Inaba at a shrine, with younger versions of Iori, Yui and Aoki. The supernatural development for the new arc, Kako Random, is that between 12 pm and 5 pm everyday, Inaba, Iori, Yui and/or Aoki will revert back to younger versions of themselves. Taichi has been spared most likely because a different Heartseed (Number Two) has informed Taichi that he has an important mission. So far this phenomenon has hit Yui and Aoki the hardest.
Episode 11 of Kokoro Connect was great. I really like the new arc, and the new developments that might come with it. It looks like we are going to learn a lot from Inaba, Iori, Yui and Aoki. I am also very intrigued by this Number Two character and what his intentions might be. I continue to look forward to new episodes of Kokoro Connect every Saturday. This episode gets a 10 out of 10.
