Dark Horse (大穴) is the 105th chapter of the Toaru Kagaku no Railgun manga series was released on May 26th 2018 in Monthly Comic Dengeki Daioh.

Synopsis
With the help of the reprogrammed security robots, Misaka Mikoto becomes victorious against the Riot Suppression Gigapedes, and their group effortlessly proceeds to the intended location of the target. Along the way, they encountered Kongou Mitsuko, Wannai Kinuho and Awatsuki Maaya, dressed in a tight-fitting suit designed by the Kongou family's conglomerate to fool computer sensors. Mikoto politely refuses the offer to use the suits, using the competition as an excuse (and her bust size insecurities as the actual reason), and the two groups head to their destination. At the control center, Kyougoku Ryouta becomes desperate and prepares to make the presumed victors' escape difficult. But, his plans to interfere with the way out is interrupted when the girls discover that the cell holding the supposed jailbreak target is empty. Aohoshi soon discovers that the footage of the target was recorded, and the actual target has been safely taken by none other than Uiharu Kazari who hacked the entire system of the complex, something that amazed the one she rescued for the trial.

As intended, Uiharu won the one billion yen reward for the successful breakout. Mikoto reveals later on that she had a hunch that only someone like Uiharu can open the doors to the Girls' Building. Uiharu then shocks the girls by stating that she plans to donate the entire reward (setting aside tax payments) to Asunaro Park which plans to expand soon... after all, according to her, she can easily hack an online bank if she wanted a lot of money. That troubling comment got Kuroko to prepare handcuffs for her colleague.
