Toaru Kagaku no Railgun Manga Chapter 066

Miscalculation (誤算) is the 66th chapter of the Toaru Kagaku no Railgun manga was released on February 27, 2014. The chapter involves Kuroko's continued efforts against Mitori and her eventual victory, as well as Misaki's final ruse against Gensei.

Synopsis
Kuroko ambushes Mitori in the sewers. Mitori is shocked that her camera, out of the thousands around, had been hacked with dummy footage, to which Kuroko replies that she had the ultimate partner for that. Kuroko then declares that she has nowhere left to run. Cornered and with no time to call her Liquid Shadow puppet, Mitori reaches for her knives, thinking about how she didn't just come down there to hide but also in case she was tracked down, as the passage limited teleportation. She then plans to shoot Kuroko with her ballistic knife when she teleports to avoid her first knife, taking advantage of her lag, taking both of them down if she attacks via teleportation instead. As Kuroko moves forward, Mitori throws the first knife, but to her surprise instead of teleporting Kuroko intercepts it with her hand. Not reacting fast enough, Mitori is then punched and then kicked down by Kuroko. Screaming, she lunges at Kuroko with the second knife but Kuroko teleports and kicks her in the back of the head. As she falls in battle, Mitori could only think of Dolly before losing consciousness.

Back with Gensei, Misaki's gamble pays off. Gensei collapses upon activating the release code, as Exterior begins to dissolve. Misaki's consciousness comes to after he does so, figuring out what she must have done, that she used her powers on herself. Misaki considered that she would unlikely be able to trap Gensei with the facility's defenses, whether or not she still needs Exterior, the need to heal the Sisters of the virus and that it is likely her last chance to capture Gensei. As such, her gamble was switching her own concepts of the limiter release code with the self-destruct code, hoping that Gensei will destroy Exterior himself using the self-destruct code as she cannot do so herself because Gensei has the access rights to Exterior.

Thus Misaki wins against Gensei.
