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 dismisses 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.

Kazari visits Ruiko, were Ruiko takes the chance to look at her panties. Ruiko starts talking about what snacks Kazari brought along with herself when her phone rings. Apparently Kuroko is also coming to visit. She teleports there in merely seconds and discusses with them that Mikoto is being stalked.

Kazari later finds a site that helps Kuroko in the slightest with her investigation.
