Episode Title:
The Divine Retribution Spell.
Episode Description:
Accelerator starts to fight Amata, but the battery for his link to the Misaka Network runs out, leaving him paralyzed and defenseless. However, he begins to move again by force of will and starts to come after Amata. Meanwhile, Tōma fights against Vento, who continues to be weakened by Testament, while Hyōka makes snow appear over the city, protecting the unconscious civilians. Vento reveals her hatred towards science because both she and her little brother got into accident at an amusement park ride that was supposedly proven to be the safest, but the hospital only had enough blood to save her alone. Tōma argues against her reasoning for her actions and manages to knock her out. Index appears in the Hound Dogs' headquarters and, thanks to Mikoto's knowledge of science, learns that Last Order is being used as a container to create the angel. She sings a song in order to sever the shackles controlling Last Order, which in turn resonates with Accelerator who awakens as a result and blasts Amata into the sky. In the end, Acqua of the Back from God's Right Seat appears and gives Vento's cross to Tōma, as her Divine Retribution has been dispelled, then warns Tōma not to fight him as he is a Saint before leaving with Vento.
