Ep. 17: Musim gugur tiba di Kota Akademi seiring karakter berpakaian musim dingin dan pengaturan tempat tinggal baru dimulai.

Autumn arrives at Academy City and the students change into their winter uniforms. Accelerator, Last Order and Kikyou Yoshikawa move out of the hospital into Aiho Yomikawa's apartment, while Misaka 10032 and three other Sisters begin rehabilitation in the city. Meanwhile as promised in their bet, Mikoto has Touma do whatever she wants, dragging him to a mobile phone shop, which is offering a Gekota phone strap for those who take out a couples plan. However, in order to qualify for the offer, they have to take a photo of themselves as a loving couple, which is ruined when a jealous Kuroko intervenes. Elsewhere, Last Order gets herself locked out of the apartment, which leads to Misaka 10032 making fun of her situation. Last Order is jealous that she is the only Misaka clone which does not have goggles, so Last Order steals and run off with Misaka 10032's goggles, which she does not take too kindly.
