Episode Title:
One Way (Accelerator).
Episode Description:
Misaka 10032 arrives at a goods station, where she prepares for the upcoming battle with Accelerator, and wonders why is she thinking about Tōma during this time. Meanwhile, at a bathhouse, Komoe continues to tell Index and Aisa that espers acquire their powers by separating them from proper reality and making their own reality and that Academy City's purpose is to facilitate this process, though Level 0s like Tōma indicate the process has not yet been perfected. Tōma reawakens and tells Mikoto that the only way to end the experiment is if he, as the weakest esper, defeats Accelerator, as the strongest esper, to prove the experiment's underlying purpose as wrong. Despite Mikoto's attempts to make him reconsider, mainly due to his injuries, Tōma leaves. Meanwhile, Accelerator battles Misaka 10032, quickly defeating her. Tōma arrives to save her, much to her confusion over why he wants to do that, and Accelerator is impressed that Tōma does not fear his power. Accelerator overpowers Tōma but is shocked and enraged when his power is unexpectedly canceled by Tōma's right hand. When the fight causes several containers to release huge quantities of flour into the air, Tōma is forced to run as Accelerator sets off a dust explosion.
