Toaru Kagaku no Railgun T Episode 23

Possession (憑依) is the 23rd episode of Toaru Kagaku no Railgun T. It was broadcast on September 11th 2020. The episode was directed by Sokuza Makoto, Horiguchi Kazuki and Tanaka Tetsuro, the screenplay written by Yasukawa Shogo, and storyboarded by Takada Kouichi, Yoshida Toru and Nagai Tatsuyuki.

The earnest intentions that led to participating in the experiment now carry the responsibility of having created the "Doppelganger". Kuriba, who tried to carry all of the burden by herself, reminded Mikoto of her own past. After going back to the origins of Kuriba's resolve, Mikoto encounters Scavenger, which was hired on a mission to capture the Doppelganger.

To compensate for the injuries she received earlier from Scavenger, the Doppelganger adopts the characteristic of integrating surrounding material into herself. Aware of the possibility that the "soul diffusion and possession" is already taking place, something that Kuriba fears, Mikoto joins forces with the Scavenger girls. Meanwhile, Scavenger's Leader aims to complete their mission by collaborating with Mikoto.

Cultural References

 * is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. This explains the cloaking technology used by the data airship seen in this episode, as it uses polarization of light to hide itself, though by Academy City standards.
 * Contrary of what Mikoto said on having low fuel in the tank make small explosions, it is the opposite. Having an almost empty tank can have bigger explosions and much more hazardous than one with a full tank, as vapours inside an empty tank are the ones that explode while the fuel just burns itself.

Differences in Adaptation

 * The conversation between Mikoto and Scavenger when they met for the first time is slightly changed. Leader is the one who tells to Mikoto on the Doppelganger's regenerative abilities, then Yakumaru clarified that it was already damaged when they encounter it. In the manga, only Yakumaru tells these lines.
 * Scenes of Leader using her Predator are anime-original, as the manga only implied she used it.
 * Mikoto having a back-up plan of using a coolant to freeze the Doppelganger is cut in the adaptation.
 * Mikoto's fight with the Doppelganger near the end of the episode is slightly extended, especially on firing her Railgun at it.

Animation Trivia

 * The 'giant puppet' created by the Doppelganger is rendered in CGI.
