"August 15, Part 2" (八月十五日① Hachi-gatsu Jū-go-nichi ②?) is the 22nd chapter of the Toaru Kagaku no Railgun manga series, released on June 27, 2009.
Misaka Mikoto confronts Misaka 9982, asking who she is, to which Misaka 9982 just replies with "Mya". Mikoto freezes up, unsure of what Misaka 9982 means. It turns out that Misaka 9982 was referring to the noise that the cat in the tree made, which ran up there as a result of the use of Misaka 9982's electrical ability. Mikoto shouts at Misaka 9982, repeating her demand to know who she is, but Misaka 9982 plays upon Mikoto's compassion of small animals. Misaka 9982 has Mikoto get on hands and knees and stands on her back to save the cat. However, the cat is instinctively frightened of the weak electricity coming off from the Electromasters' bodies. Mikoto shouts in frustration as she realizes that Misaka 9982 evaded the question once again and asks her if Misaka 9982 is Mikoto's clone. Mikoto asks why she exists, due to the dissolution of the project, to which Misaka 9982 asks for the confirmation code. As Mikoto is unable to give her the code, Misaka 9982 is no longer willing to answer her questions. Mikoto threatens Misaka 9982, but is (obviously) unable to hurt her and instead lets her go.
Mikoto decides to follow Misaka 9982, hoping to be led to the institution or research centre where the clone was created. However, she realizes the significance of the term 'Sisters' and shouts her questions, frustrated. A ice-cream truck passes the arguing sisters and the sympathetic ice-cream salesman stops gives two ice-creams to Misaka 9982 and Mikoto, to try to 'heal' their relationship. Misaka 9982 compliments the ice-cream salesman for the great ice-cream and he drives off. Mikoto, distracted by the salesman'd words, doesn't notice Misaka 9982 eating her ice-cream. Misaka 9982 then decides to go for some hot tea, with Mikoto accompanying her.
After an entire day of chasing Misaka 9982 around, she informs Mikoto that she would not be returning to her creators. Mikoto rifles through her pockets for her phone, intending to try decrypting the passcode Misaka 9982 mentioned earlier, causing the previously won Gekota badge to fall out. Mikoto tests out the look by pinning it onto Misaka 9982's jumper, but the clone considers it childish. An embarrassed Mikoto reaches out to take back the badge, but her hand is slapped away. After a flurry of attempts, Misaka 9982 successfully fends off Mikoto. She claims that ownership of the badge transferred when Mikoto attached it to her, and notes that it's the first gift she received from her (although she does wish she got something better).
Mikoto says goodbye to Misaka 9982, wanting to find the creators by herself, and as she's running she gets the feeling that Misaka 9982 felt like a real sister. She calls up Uiharu Kazari, asking about the confirmation question that Misaka 9982 asked when Mikoto first met.
At the same time, Misaka 9982 retrieves a guitar case from a public locker. She heads to an alley to meet Accelerator, telling him to move to the designated area as the experiment is beginning soon. Accelerator smiles.
