Toaru Kagaku no Railgun S Episode 17

"Study Session" (勉強会) is the seventeenth episode of the second season of the Toaru Kagaku no Railgun anime adaption, and the 41st episode overall. It was broadcasted on August 2, 2013. The screenplay was written by Tsuchiya Michihiro, storyboarded by Sayama Kiyoko, and directed by Ikehata Takashi. Its animation was co-directed by Fujibe Ikuma and Moroishi Kouta.

The right fist of the "weakest" has brought an end to the incident surrounding Mikoto's clones, the Sisters, and peaceful everyday life has returned. Mikoto and Kuroko slip past the strict dorm leader's inspection to gain permission to leave. They want to participate in the study group (which is actually a nabe party) being held in Saten's room. This is a plan for Mikoto to make up for her recent neglect of Kuroko and the others. Until they meet up that evening, Saten, Uiharu, and Kuroko enjoy their free time separately. Meanwhile, Mikoto visits the frog-faced doctor's hospital the Sisters are staying at.

Quotes

 * Mikoto: "I-It's just that I'm in debt and it's, like, not my style to be indebted to anyone. I thought store-bought cookies would be enough, but no, it wasn't. They have to be homemade. That idiot... B-But it's not like I'm doing it for someone specifically! It's just, like, you know... "see how much I did for you?" kinda thing."—to Ruiko regarding what the cookies were for.
 * Ruiko: "Shirai-san was pretty obvious about it, but Uiharu and I were worried about you too. I might not be the most reliable person, but I'm glad I could at least help you out with this."—to Mikoto.
 * Ruiko: "She's so cute! Even though she's making a mess..."—regarding Mikoto as she becomes flustered after Ruiko references her "boyfriend".
 * Mii: "So I suppose our legendary goalkeeper's one weakness is writing book reports."—to Kazari regarding her epithet.
 * Heaven Canceller: "They've got a long fight ahead of them. But this time, they're not fighting to die. They're fighting to live."—to Mikoto on the fate of the clones.
 * Mikoto and Shizuri: "What the hell do you think you're touching?!"—to Kuroko and Frenda respectively.
 * Mikoto: "Let's go"—to Kuroko as they go home.
