Toaru Kagaku no Railgun: Following the Poltergeist incident, Mikoto wonders if Harumi is once again involved, though Kuroko dismisses it since she's still in custody. Kuroko instead suspects Erii to be the cause due to the fact most of the Poltergeist attacks have been occurring at places she has been. Both of them do an illegal background check on Erii where they learn that despite being a Level 2 Telepath, she can exhibit Level 4 powers under certain catalysts. Due to the incident at the festival, Kazari decides to take Erii to a park to cheer her up where Erii reveals she is looking for her childhood friend. However, Erii goes into a trance again right before a violent Poltergeist attack occurs at the park. The girls go to the hospital where Kazari becomes angry at Kuroko for suspecting Erii. Telestina meets the girls and decides to do some tests on Erii at the MAR's headquarters to prove her innocence. Despite the tests confirming Erii's innocence, Kuroko remains skeptical. Finally awake, Erii explains to everyone that she would go into a trance upon hearing the voice of her friend, Banri Edasaki, who, upon showing them a picture of her, Mikoto recognizes as one of Harumi's students.
