Episode Title:
Sisterhood.
Episode Description:
Accelerator demands to know why Mikoto is protecting Misaka 10032, to which she responds that it is simply because she is her sister. Before Accelerator can attempt to kill them, Tōma manages to regain his footing and uses the remainder of his strength to knock Accelerator out with one final punch. As he loses consciousness, Accelerator comes to the realization that the reason he wanted to become a Level 6 in the first place was so that he would not have to hurt anyone anymore. After the experiments are cancelled as a result of Accelerator's defeat, Mikoto goes to the hospital to visit Tōma, who assures her that even though many Sisters died, it was thanks to her 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 at the playground and think about the future that lies ahead. The next day, Mikoto borrows Ruiko's kitchen to make some handmade cookies for Tōma as thanks for his help. Despite not getting an opportunity to give them to him, Mikoto feels pleased when he finally calls her by her proper name.
