Toaru Kagaku no Railgun Manga Chapter 107

Monster (怪生) is the 107th chapter of the Toaru Kagaku no Railgun manga series, released on August 27th 2018 in Monthly Comic Dengeki Daioh.

Synopsis
Sometime in the past when Kimi was still in the Reformatory, Aohoshi talked to Kimi on how the latter has somehow gained a dragon, something that Aohoshi did not take seriously that time.

Some time later, Aohoshi recalls how she planned with Raifu and Tsurigane to break out Kimi, with a search for someone with great hacking skills as a secondary objective. Raifu is assigned in thin out the competition, while Tsurigane agreed to use her connections with her trusted former ninja comrades led by Oumi Shuri, using them as a guarantee that they will win the competition despite failing to find a skilled hacker. At the beginning, Aohoshi remained skeptical about the idea of having "dragons" and "ninja" at their side, dismissing it as a kind of "teenage disease". This eventually came back to bite her as she realizes that ninjas and dragons are actually real.

Aohoshi soon reveals that she has obtained the registration data on the winner, Uiharu Kazari, whose performance in the Jailbreak Trial took them by surprise. Raifu comments on how Uiharu was with the Railgun, which surprises Kimi as she is largely uninterested of the status of the Level 5s while she was incarcerated. Although Aohoshi says that the city's strongest espers are said to rival a navy cruiser's in firepower, Kimi seems unimpressed, confident that "the weakest card can beat a joker".

At Joseph's Coffee and Restaurant, Uiharu reveals through her hacking that there was supposed to be a long-ranged AIM Jammer in the 2nd Juvenile Hall, something that could have easily prevented Mikoto and Kongou's tactic to penetrate its outer walls but wasn't used during the entire event. Mikoto then congratulates Uiharu for beating her and joins Saten in urging her to be more proud of her ability now that she has used it to help someone through her hefty donation to Asunaro Park. As Uiharu enjoys her meal, Kuroko arrives to call her out for skipping patrols, and wonders if she is getting lazy thanks to her injury. Uiharu uses her recent victory in the Jailbreak Trial as an excuse to eat sweets (to "keep her brain at top shape" like the practice of professional shogi players), which Kuroko disregards. With her moment at the top cut short, Uiharu is dragged off by Kuroko for another round of patrols.

Later that night, Uiharu and Saten chat by phone on how she spent the rest of the day on patrol with Kuroko. During the call, Uiharu hears her doorbell. Assuming it is a package, Uiharu hangs up on Saten and tells her she will call back. When Uiharu's line remained dead for an extended period of time, Saten becomes worried rushes to her apartment, contacting Kuroko and Mikoto about it. She fears that people might have known about her winning the competition and is interested in taking the prize money.

Saten is joined shortly by Mikoto and Kuroko at Uiharu's apartment unit, left unlocked. Upon checking inside, Saten confirms that Uiharu is indeed missing.
