A Certain Scientific Railgun

The girls are unable to find out any more information from Febri, as she appears to be a bit cautious around Mikoto and takes a liking with Ruiko. Kazari invites Ruiko and Febri to her apartment to spend the night. The next day, the group fails to find any background information on Febri, believing her to be a Child Error, so they make arrangements for her to be moved to the orphanage in Asunaro Park. As the gang heads out where the Academic Assembly Exhibit will be held, Ruiko sets up some time for Mikoto to get along with Febri on their own. However, Febri gets lost when she wanders off and follows a Gekota mascot who is actually Pierce Aogami whilst Mikoto wasn't looking. Aritomi spots her and sends some security bots after her, but Mikoto manages to save her in time. Afterwards, Ruiko has Febri apologize to Mikoto for worrying her which young girl finally accepts Mikoto. With Mikoto now involved, Aritomi and his colleagues decide to experiment on her as well.
