Toaru Kagaku no Railgun S Episode 14

Promise (約束) is the fourteenth episode of the second season of the Toaru Kagaku no Railgun anime series and the 38th episode in the series overall. It was first broadcasted on July 12th, 2013.

For Oneesama, what else can she say and do but wait patiently? Kuroko does so with determination, though this determination begins to wane when her concerns for Mikoto's everyday-absences rear up in her mind. As she worries, a surprising person appears before her—Touma an acquaintance of her Oneesama.

In an attempt to get even a small clue about what Mikoto is dealing with, Kuroko allows him to enter their room. However, the Dorm Supervisor and her troublesome patrols have come, and she is forced to hide Touma away underneath a bed. Despite his stifled breath under the bed, he finds something intriguing within Mikoto's Kirigumar—the truth hidden behind the "experiments" that the Sisters he had met had spoken of. Touma, now knowing that Mikoto is fighting a battle on her own, hastily sets off running around Academy City in the dark of the night.

Meanwhile, Mikoto has been forced to bring out her final trump card, and now must make a difficult choice...

Quotes

 * Kuroko: "How dare you call me a pervert." — To Touma as he asks about Kuroko spending her time on another person's bed
 * Mikoto: "Help me. Please, help me." — Her anguished plea for help as she discovers her helplessness in the battle against the Level 6 Shift Project.
 * Mikoto: "..Even being the meddler that you are, I bet you can't look past this. From your point of view, I'm just an accomplice who provided the DNA for these experiments. Are you here to blame me? Whatever. Even if I'm wrong, the results show the opposite. For all I know, having someone else blame me might calm me down a bit." —Internal monologue regarding Touma discovering the experiments.
 * Touma: "Yeah, they are wrong. There's no reason for someone to get hurt by that. But... the way you're handling it won't save you. That's why I'm not moving." — Touma's words of conviction as he stands in Mikoto's way
 * Mikoto: "Even if there was a world where everyone could live happily, I would have no place there!" — Mikoto's words to Touma, signifying her succumbing to her fate
 * Mikoto: "You really are stupid. This has nothing to do with you. Just close your eyes and pretend like you never saw anything. You could still go back to your ordinary life. Why would you let yourself get beat up like this? Your heart might've stopped for a bit too. How can you keep smiling like that?!"—To Touma as she has his head on her lap.
 * Touma: "Because I'm glad to be your friend."—Touma's reply to the above sentence.
 * Touma: "So... How about you help me, then? It's my dream to go back home smiling, without having lost anything. So help me fulfill that. Just wait here. I'll bring back younger Misaka. I promise."—To Mikoto just before leaving to confront Accelerator.
