Toaru Kagaku no Railgun S Episode 22

"STUDY" is the twenty-second episode for the second season for the Toaru Kagaku no Railgun anime adaption, and the forty-fifth episode overall. It was first broadcasted on September 13, 2013. It was directed by Takashima Daisuke, screenplay written by Tsuchiya Michihiro, and storyboarded by Sayama Kiyoko. The animation was co-directed Moroishi Kouta, Komatsubara Sei, and Shigeki Kimoto.

The time left for Febrie is 72 hours.

In order to obtain a clue to save her, Mikoto goes to where Therestina is being imprisoned. This is because Therestina is someone who is known for experimenting on the children living of Academy City after all. However, Mikoto is warned that to taste a glimpse of the darkness, she may never look the same at the city ever again, even hating it.

The two stare at each other, but Therestina nonetheless give Mikoto a clue. The clue is that Febrie is something called a Chemicaloid, made by the people who go to the Academic Assembly. Meanwhile, in the surface, ITEM receives information from the people who had hired them under false pretenses...thus starts the action.
