"Sisters" is the 11th episode of the Toaru Majutsu no Index anime series. It was first broadcasted on December 14, 2008, with the script written by Nishizono Satoru, the episode storyboarded by Yanagisawa Tetsuya, and directed by Tsuruta Hiroshi.

Touma and Misaka Imouto picked up a black together, with the former visiting a bookstore in order to find a book on how to look after a cat. While Touma is in the store, Misaka Imouto is outside looking after the cat, however, the cat begins trembling as a black figure approaches and Misaka Imouto leaves it behind as she deals with. Touma returns to find that she is gone and only the cat remains, and there, he goes towards a suspicious narrow back alley to a familiar leather shoe, and then finally, he finds a figure of a girl in the uniform of Tokiwadai Middle School—Misaka Imouto collapsed on the ground in a pool of her own blood. Touma reports the incident, and when he is asked to revisit the scene, the body is gone, no traces can be found, not even the blood or the leather shoe. However, Touma later finds something in his peripheral vision an impossibility, it is Misaka Imouto carrying a body bag and many other Misaka Imoutos.

Synopsis
In the shadows of the alleyways runs Mikoto's sister. She is breathing heavily, while carrying gun and wearing her goggles that glows a tealish color. She keeps on running, even when one of her shoes has fallen off; she removes her other shoe as so she can run properly. Suddenly, a voice is heard speaking. It is the voice of her tormentor, Accelerator. He asks her why she is running, and taunts her on how she is flashing herself to him. Mikoto's sister stops and fire several bullets towards him, seemingly hitting Accelerator. Suddenly, the bullets fly back towards her, and one of them hits her right shoulder. The force of the impact collapses her to the ground. Accelerator is still alive, unharmed. He comes closer to her and asks her what exactly he is doing. He leans forward; however, the girl fires her gun to his face. Strangely, the bullets stops in midair, and is redirected to her. Thinking quickly, she shields herself with her gun, and throws it towards him immediately after, though destroying her gun. She runs away, putting a little distance between her and Accelerator. She attacks him with her electric powers, however, it does not work and Mikoto's sister gets electrocuted by her own powers. She collapses and breaks several glass bottles near her; even in pain she realizes what Accelerator's powers is, "Reflection". Accelerator quickly says that she is incorrect, and that his power is "Vector change". He enumerates a list of things that he can control and tells her that anything that has vectors can be changed by him with a touch, and states that his power is set to reflect by default. Accelerator leans down and touches the open wound of Mikoto's sister. Accelerator tells her that he is now touching her blood, and asks her quizzically on what would happen to the human body if the direction of the blood flow is reversed. He smiles widely and tells her that if she answers correctly she will be given a peaceful rest, to her horror.

Meanwhile, Mikoto stands alone with a determined look upon her face, looking at the sky.

Cultural References

 * Misaka 10031 uses a in her fight against Accelerator, which is a fully-automatic bull-up assault rifle. Despite it's bulky size, it only weighs 3.6 kilos.
 * Despite what Accelerator said to Misaka 10031 about his powers, heat is not a but a . Which means that Accelerator's powers may encompass scalars as well. However, if one logically looks at heat, it is the vibration of molecules, which means matter moving back and forth. This means that he could be controling heat indirectly though the vectors of the molecules themselves, but this is unconfirmed as the extent of Accelerator's powers and how exactly it can redirect vectors of even minute objects has not been shown.
 * What Komoe, Aisa, and Index are cooking in Komoe's apartment is called a, which literally means "grilled meat".

Animation Trivia

 * Touma's eyes become off-model during the scene where he realized that Misaka 10031's body went missing.
 * During Touma's bus trip to the Tokiwadai Dormitory, the first reflection we see of Touma's body has him missing a part of his neck on the reflection after the mettalic part of the window cuts of the reflection of his face. The next reflection however, shows Touma's reflection normally.

Quotes

 * Accelerator: "Sorry, that's not quite the true nature of my skill. The answer is 'vector change'. Momentum, heat, electric charge. All kinds of vectors can be changed with just the touch of my skin." -Accelerator revealing his powers to Misaka 10031.
 * Accelerator: "Now, time for the consolation prize question. I am now touching the flow of blood. If I reversed the direction of the flow, what would happen to a human's body? A correct answer and you will be given a peaceful...slumber." -said to Misaka 10031 before killing her.
 * Misaka 10032: ""Misaka did actually die," reports Misaka." -Misaka 10032, confirming Touma's suspicions.
 * Touma: "If I see her, then what? Am I going to ask about the details of a horrifying experiment where people get killed easily?"
 * Kuroko: "And, you must be the gentleman that has been quarreling with Oneesama frequently, right? Forgive me if I'm mistaken. I simply wanted to see the face of the one that has been giving Oneesama support." -said to Touma.
