Synopsis
Soon, Kihara Amata witnesses the unleashing of Fuse=KAZAKIRI from the building he is in, and is amazed at how Aleister, a man of science, can reject science at that moment by creating an angel. Soon, he is startled by Accelerator's entrance from outside the building. Accelerator kills off Amata's Hound Dog units and prepares for another battle with his mentor.

Meanwhile, Touma finally reaches the center of the angel's manifestation. However, he feels helpless as he knows that one touch of the Imagine Breaker would ultimately kill her. Soon, Vento reappears and declares that she must kill a monstrosity like Hyouka must die along with him. Touma then prepares to fight Vento for another battle.

Trivia

 * The episode would mark the first time Touma and Accelerator would speak to each other since their confrontation in the 14th episode of the first season.
 * Accelerators attack on the Windowless Building is depicted much weaker and slower then described in the light novels, where it is described as being much faster and also destroying several other structures on the way to its target.
 * There are more than 10 Misaka clone in Academy City, furthermore, during the activation of the virus that would make Fuse=KAZAKIRI manifests, Misaka 10032 is the only clone apparently able to move and speak.

Referbacks

 * Touma uses the cellphone Last Order dropped during Vento of the Front's attack on Touma from the previous episode.
 * The bridge where Touma and Vento of the Front meet up again look like the same bridge that Mikoto uses Railgun on Touma for the first time from episode 1 of the first season, as well as the same bridge where Touma confronts Mikoto about the Level 6 Shift from episode 12 of the previous season.

Cultural References

 * Accelerator pulls several pins from what looks like an, which should realistically killed everyone in the office apart from Accelerator.

Animation Trivia

 * When Accelerator launches his attack on the Windowless Building, the building he launches at it simply bounces off sustaining little damage before falling back and then collapsing. A building travelling at that speed should have completely shattered upon hitting the target.
 * This episode would mark a new animation for Aleister Crowley's appearance.
 * Misaka Mikoto firing her Railgun is a recycled animation from the first Toaru Kagaku no Railgun Episode.

Unanswered Questions

 * Where did Index come from, and how does she know that the angel is actually Kazakiri Hyouka? (See Volume 13, Chapter 9, Part 3)

Quotes
