A Certain Scientific Railgun S

Season 1

Episode 19: Academic Research Assembly

The girls are unable to find out any more information from Febri, who appears to be a bit cautious around Mikoto and takes a liking with Ruiko. After Febri spends a night with Ruiko at Kazari's apartment, the group, believing Febri to be a Child Error, make arrangements for her to be moved to the orphanage in Asunaro Park in a week. As the gang heads to where the Academic Assembly Exhibit will be held, Ruiko sets up some time for Mikoto to get along with Febri on their own. When Febri wanders off while Mikoto isn't looking, the man from before spots her and sends some security bots after her. Luckily, Mikoto manages to rescue Febri, who apologizes for making her worry and comes to accept her. With Mikoto now involved, the man and his colleagues decide to include her in their experiments.
