Toaru Kagaku no Railgun S Episode 17

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 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.
