Biribiri scored her first big win of the arc against Shokuhou and whatever shadowy organization (*cough*MEMBER*cough*) she’s working for, but could she build on the momentum gained by sending Baba packing? Thankfully, her friends are helping connect the dots, even if in Saten’s case she doesn’t know they’re friends! The psychometric girl gleans a clue from reading MISAKA’s cat’s mind.
Saten is also the first to consider that Shokuhou may have altered her, Uiharu, and Kuroko’s memories, which would explain why she has Misaka’s number on her phone. Uiharu is still in the dark, and yet she knows Misaka’s Mama, and explains to her how everyone with an entrance pass also has a GPS so Judgment and Antiskill can keep tabs on them. Little do the two know they’re being stalked by Baba’s mysterious contact, a girl in purple (I went to the wiki to learn her name is Kouzaku Mitori).
In the middle of arranging to meet with Saten and Kuroko, Misaka’s phone call is interrupted by Kouzaku, who threatens Uiharu and Mama with a knife (in two different spots) unless Misaka tells her the locations of the Sisters clones. Likely still humming from her ownage of Baba, Misaka defiantly clams up, justifiably confident her currents are faster than Kouzaku’s knives.
Misaka saves Uiharu in a novel, very Railgun way: by launching her to safety using the metal supports of the bench, then disarming and neutralizing Kouzaku. This leaves Mama unprotected, but Kuroko teleports to her location and tosses her wheelchair at the second Kouzaku. Misaka has Kuroko teleport Uiharu and Mama to a safer place, but Kouzaku’s liquid metal puppet eventually melts, its operator apparently out of range.
When Kuroko asks Misaka why she chose Uiharu over Mama, Misaka tells her her Mama wouldn’t be happy to hear her daughter saved her before someone else. Misaka also knew Kuroko knew her location would be able to teleport there in under ten seconds, and had faith in Kuroko’s ability to save Mama.
This praise makes Kuroko blush despite herself, and she blushes more when Misaka insists on drawing close to help her walk. It’s immensely fun and hilarious to watch “Tsundere Kuroko” squirm with discomfort in the same situation where she’d normally shudder with bliss. It’s as if she’s falling in love with Onee-sama all over again! Arai Satomi is killing it.
With everyone safe for the time being (except of course for MISAKA), Misaka, Saten and Kuroko continue to try to piece things together at the Judgment office. There, Saten brings up the urban legends website that she and Uiharu were using to try to track the Shadow Metal. They discover that Shokuhou Misaki likely used her power to make Uiharu tamper with the site and alter her memories.
When Misaka reactivates Uiharu’s computer, the data on the site has been reconstructed, revealing a particularly inflammatory urban legend about a “DNA computer” that “generates abilities”, and a prominent photo of Misaki in a garage with men in white coats. Perhaps that’s where MISAKA is being held? If not, at least it’s a new lead, and more evidence with which to implicate Misaki.
