Kouzaku attacks Kuroko, manipulating her puppet with such precision despite having its "eyes" and "ears" disabled. However, Saten was able to find the key to exposing Kouzaku's secret: a miniature camera used for the relay events in the Daihaseisai. After being informed by Uiharu about the possibility that Kouzaku may be using a similar device, Kuroko used everything she knew thus far to guess where Kouzaku is located. With this strategy on hand, she comes out to challenge Kouzaku directly.

Meanwhile, a grotesque-looking Mikoto continued her rampage, while Kamijou and Sogiita's do-or-die actions were to no avail. After driving Shokuhou to a corner and obtaining the code, Gensei unleashes the final trigger to Mikoto obtaining Level 6: the release of the Exterior's limiter!

 * With the help of Saten's suggestion and Uiharu's hacking skills, Kuroko pinpoints Kouzaku Mitori's location and apprehends her.

Trivia

 * According to Ogino Kentarou, the Railgun manga's editor, the reason for the four minute long recap at the beginning of the episode was due to the inconsistent airing of the episodes due to the COVID-19 pandemic.
 * The episode preview shows Touma doing his style of narration he does for his preview narrations in the main Index series, as well as the ending line "When magic and science cross paths, the story begins!" for the first time in an animated adaptation of Toaru Kagaku no Railgun.

Referbacks

 * Kuroko narrates the first four minutes of the episode, making it the longest recap in any Toaru series anime to date. The following episodes are used as recap scenes:
 * Kuroko, Uiharu and Saten not remembering Mikoto due to Misaki's Mental Out;
 * the gang meeting Kongou and her posse, with Kuroko venting her frustration towards Mikoto;
 * Kuroko discussing with Saten regarding the current situation with Mikoto, as well as Mitori's Shadow Puppet's attack on Kuroko and Mikoto thanking her for saving her mother;
 * Mikoto promising Kuroko and Saten to restore their memories;
 * Kuroko finding Mitori's bank data, as well as the incident inside Shinohara Liquid Material Factory;
 * Misaki struggling with Mitori's shadow puppet and Kuroko saving her, Misaki 10032 and Keitz, Misaki using Mental Out on Kuroko, Touma and Gunha fighting Mikoto in her initial transformation;
 * and finally, Mikoto shifting her form and Kuroko's quest on finding Mitori's location while being chased by her Shadow Puppet.
 * Scenes of Dolly from ' are used as flashbacks when Misaki remembers her. In addition, scenes of Misaka 10032 from ' and  are used as flashbacks as well.

Differences in Adaptation

 * The dead end corridor, the final spot where Kuroko is looking for Mitori, was redecorated from just a single plant to having a vending machine and some seats.
 * Mitori's puppet exited the air vent directly before confronting Kuroko, unlike in the manga where the puppet unscrews the vent first before popping out.
 * The transformed Mikoto knocks Gunha out with her powerful electric attack in this episode, unlike in the manga where he is knocked out by her ribbon-like things.
 * Kuroko's one second teleportation lag is not referenced in this episode due to her teleportations in previous episodes having a small delay for up to minimum of 0.4 seconds, whereas Mitori states in the manga that Kuroko has one second delay between teleportations.
 * Kihara Gensei only types the supposedly limiter release code in mind in this episode, unlike in the manga where he speaks it out loud. This makes the code unknown in anime continuity.

Animation Trivia

 * At least 4 minutes of footage from previous episodes,     as well as least one minute of footage from the  are reused as recaps before original scenes are shown.
 * In addition, the first four minutes are narrated by Kuroko over the character's dialogue during the recap, akin to an audio commentary.
