Although Therestina mech is unaffected by Mikoto's basic attacks, she manages to destroy the mech with a powerful railgun with Kuroko's assistance. Mikoto, Kuroko, Kazari, Ruiko and Harumi finally arrive at the underground lab where the children are, but before they can do anything, the lab's Capacity Down is activated, revealing that Therestina has survived and proceeds to beat everyone down. Therestina reveals her plans of using the first sample from herself and the children to turn Erii, due to her unique powers, into a Level 6 at the price of the destruction of the city. As all hope seems lost, Ruiko, the only one not affected by Capacity Down, destroys its controls, allowing Mikoto to defeat Therestina with her railgun. With the first sample in hand, Harumi creates the cure which finally awakens Banri and the other children, giving her thanks to Mikoto. In the aftermath, the recovering children give a birthday message to Harumi via a blimp as Mikoto and her friends watch.|

After punishing Kuroko for sleeping on her bed, Kuroko tries to take Mikoto through an alleyway to get to the mall, only to find it filled with people. They discover this is due to someone hiding envelopes containing cash cards within the alleyways, piquing people's curiosity to search for them. After running into Ruiko, who is also on the hunt for the money cards, Mikoto overhears some SkillOuts who have managed to locate the source of the envelopes and decides to follow them. Meanwhile, Ruiko grows curious as she had allegedly seen Mikoto at the mall, despite Mikoto never actually getting there, with Mii explaining to Kazari about a rumor of there being clones of a Level 5. The SkillOuts eventually trace the envelopes back to a girl, a Nagatenjouki Academy student, and demanding she hand over the other envelopes.

As Accelerator takes his leave, Mikoto feels no comfort in hearing the Sisters acknowledge themselves as nothing more than guinea pigs. After a restless night, Mikoto is approached by Shinobu, who explains why she chose to oppose the experiment.

She hears how Minori wanted to find a lucky item for her friend who is moving away, with Kazari and Ruiko also deciding to help out. After pointing out cash cards would be out of the question, since they would need to be turned into Judgment, Mii suggests that they instead search for a four-leaved clover. During their search, Kazari and Ruiko give Kuroko some assurance that Mikoto, along with themselves, appreciate her efforts.

Meanwhile, Shinobu, who felt Mikoto shouldn't have to carry her burden alone, sneaks into the basement of her facility where the incubated Sisters are being held. There, she intends to install emotions into all of the remaining Sisters via the Misaka Network in the hopes it may move the organizers to suspend the experiments. However, she is apprehended by ITEM's fourth member, Saiai Kinuhata, who was guarding the facility in case a second party was involved in the attacks. Shinobu manages to get the program installing, but it is suddenly blocked by an unforeseen error code, labelled "Breach code no. 20001". Shinobu fires a gun at Saiai to save herself, but her attack fails due to Saiai's Offense Armor ability and she is taken into custody. Back at the other facility, a weakened Mikoto is forced to use her ability to deflect Shizuri's Meltdowner attack, making her realize who the intruder's identity is.

After finding and destroying the facility's data bank, Mikoto finds herself on the run from an angered Shizuri.

Arriving at Tree Diagram's control center, hoping to hack into Tree Diagram to order a halt to the experiment, Mikoto is confused to find it not only heavily low on security, but completely abandoned as well.

She tries to cling onto her cause by mercilessly destroying another facility, but loses all hope when she sees a live feed of Misaka 10031 being killed by Accelerator. As Accelerator reminisces about his first experiment and his first time killing a Sister, Tōma discovers Misaka 10031's corpse and calls AntiSkill to investigate it, only to find it gone when they arrive, with no evidence it ever occurred. After the AntiSkill leave, Misaka 10032 appears before Tōma, who comes to learn the true nature of the Sisters. Upon learning this, Tōma heads for the Tokiwadai dorms to try and get some answers from Mikoto, who at the same time is contemplating her last resort.|

|Tōma arrives at the Tokiwadai dorms, where he is reluctantly greeted by Kuroko, who decides to let him wait for Mikoto return. When the Dorm Supervisor comes by for an inspection, Kuroko is forced to hide Tōma under Mikoto's bed due to his powers negating her teleportation. There, he finds the details concerning the Level 6 Shift project stuffed inside her 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 the only way to stop the experiments now is to prove she doesn't live up to Tree Diagram's expectations of her power by letting herself be killed by Accelerator in a single move. However, Tōma, feeling her way won't 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 shockwave 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 his own idea; that if he, 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.|

As their fight begins, Tōma initially struggles against Accelerator as he launches projectiles at him and sets off a dust explosion. However, Accelerator is shocked when Tōma is able to punch him with his right hand, also coming as a surprise to Mikoto, who had also rushed to the scene. Angered, Accelerator starts using his ability to manipulate the wind, creating a huge hurricane that deals a lot of damage to Tōma. Mikoto attempts to go with her original plan in order to save Tōma, only to realize it would be futile upon witnessing Accelerator using his power to create a plasma storm that would wipe out everything in the area. Realizing what can be done to stop it, Mikoto goes over to Misaka 10032 and begs for her help in protecting Tōma's dream. Moved by these words, Misaka 10032 uses the Misaka Network to command the other Sisters in Academy City to use their electricity to manipulate the city's windmills, affecting the wind and disrupting Accelerator's calculations, preventing him from stabilizing the plasma. As Mikoto prepares to stand off against Accelerator once more, Tōma gathers the strength to stand up.|
|July 26, 2013|
|Accelerator demands to know why Mikoto is protecting Misaka 10032, to which she responds that it is simply because she is her sister. Before Accelerator tries to kill them, Tōma manages to regain his footing and uses the remainder of his strength to beat Accelerator with one final punch. As he is knocked out, Accelerator comes to the realization that the reason he wanted to become a Level 6 in the first place was so that he wouldn't have to hurt anyone anymore. After the experiments are cancelled as a result, Mikoto visits Tōma in hospital, who assures her that even though many Sisters died, it's thanks to Mikoto that they got to be born in the first place. Afterwards, Mikoto takes a walk with Misaka 10032, where they play with another pair of sisters and think about the future that lies ahead.
