A Certain Scientific Railgun Full Episode Guide

  • Shirai, Konori, Kongo and friends, and Uiharu and Saten confront the powered suits at the four Assembly sites, where they soon receive backup. Misaka and Febrie move to take on Aritomi directly, but he has one final surprise up his sleeve for them.

  • Therestina reluctantly provides Misaka with the clues she needs to find the group behind Febrie's secret. With Kongo's help, the girls identify Aritomi as the man they are pursuing, and find out more about him and his company, the STUDY Corporation.

  • With the revelation that Febrie is synthetic, Misaka is determined to find whoever built her, and have them fix her. The investigation is stalled on all fronts, even with the help of her friends running down leads, until help comes from a surprise source.

  • Febrie takes an instant liking to Saten, and is warm to everyone except for Misaka, much to her chagrin. At Judgment, Uiharu is unable to find any information on who Febrie is, so arrangements are made to admit her into an orphanage as a "Child Error."

  • Edasaki is due to be discharged from the hospital, and it is learned that she will be living with Haru'ue. The move is bittersweet for Uiharu, who is losing her roommate, but she feels it is for the best. Meanwhile, a new movement is afoot in the city.

  • With the end of summer vacation approaching, the girls plan a study session at Saten's apartment to catch up on homework. Everyone is to bring an ingredient for a potluck stew party, but most have trouble deciding what to buy, leading to some surprises.

  • Misaka stands up for clone #10032, declaring that she is doing so because they are sisters. The next day, the two of them spend time in a park, where 10032 asks her for a special favor. Later, Misaka has difficulty trying to express her thanks to Kamijo.

  • While Shirai frets about Misaka staying out again all night, she receives a visit from Kamijo, who manages to find Misaka's documents about the project. Kamijo catches up with Misaka on a bridge, where he tries to talk her out of doing anything rash.

  • Thwarted in her attempt to sabotage Tree Diagram, Misaka takes her frustration out on a nearby lab that is part of the project. Meanwhile, Accelerator and #10031 carry out their experiment, while Kamijo searches for Misaka's missing sister.

  • Misaka sets out on one last mission to put a halt to the experiments by destroying the supercomputer Tree Diagram. Meanwhile, Kamijo runs into Misaka's clone #10032 again, and the two of them decide what they should do about a stray kitten she has found.

  • Having realized who Misaka is, Mugino decides to give her a run for her third-place ranking. When Frenda mistakenly leaves her doll-bombs behind while heading to the other facility, Misaka collects them and uses them to supplement her diminished powers.

  • Misaka manages to sabotage most of the experimental facilities remotely before she is cut off, leaving her to deal with the rest in person. Shirai resolves to help Misaka by doing her part to be more vigilant at work, but risks shutting the others out.

  • Finding herself face-to-face with a clone of herself, Misaka ends up helping her get a cat out of a tree, sharing ice cream cones, and having tea with her. It isn't until later that Misaka discovers the true, sinister project that calls for her clones.
