Episode Title:
The Promise.
Episode Description:
Tōma arrives at the Tokiwadai dorms, where he is reluctantly greeted by Kuroko, who decides to let him wait for Mikoto return. When the Tokiwadai Dorm Supervisor comes by for an inspection, Kuroko is forced to hide Tōma under Mikoto's bed due to his Imagine Breaker negating her teleportation. There, he finds the details concerning Project Level 6 Shift stuffed inside a teddy bear, learning that Misaka 10032's experiment is next. Tōma follows a trail of windmills to a bridge where he eventually finds Mikoto and confronts her about the experiments. With all her other efforts failed, Mikoto feels convinced that letting herself be killed by Accelerator is the only way to stop the experiments, proving she does not live up to Tree Diagram's expectations. However, Tōma, feeling her way will not save anyone, decides to stand in her way, refusing to fight back or even defend himself from Mikoto's lightning. Mikoto's emotions soon build up into a large shock wave that Tōma takes the full brunt of, helping her to see his resolve. After regaining consciousnesses and being greeted by a tearful Mikoto, Tōma comes up with the idea that if he as a Level 0 can defeat the Level 5 Accelerator in a fight and prove him to be actually weak, the entire basis for the experiments would fall apart. Despite Mikoto's objection, Tōma heads off to where Misaka 10032's experiment is being held.
