A Certain Scientific Railgun Season 2 Episode 16

Sisters

Accelerator demands to know why Mikoto is protecting Misaka 10032 and is surprised to hear her answer that she is her sister. Before Accelerator tries to kill them, Tōma manages to regain his footing and uses the remainder of his strength to beat Accelerator with one final punch. As he is knocked out, Accelerator comes to the realization that the reason he wanted to become a Level 6 in the first place was so that he wouldn't have to hurt anyone anymore. After the experiments are cancelled as a result, Mikoto visits Tōma in hospital, who assures her that even though many Sisters died, it's thanks to Mikoto that they got to be born in the first place. Afterwards, Mikoto takes a walk with Misaka 10032, where they play with another pair of sisters and think about the future that lies ahead. The next day, Ruiko and Kazari discuss about Mikoto using Ruiko's kitchen to make some handmade cookies which are for Tōma as thanks for his help.
