Saten talks with Kazari on the phone about several things one of them being that she saw someone exactly like Mikoto in front of the Seventh Mist. Kazari just dissmisses the topic while Ruiko keeps thinking about it.

Later, on another day, Kuroko calls her on the phone and asks her if Mikoto visited her. She comes to the conclusion that Mikoto might be out with a guy which ends with Kuroko yelling at her.
