Scavenger (屍喰部隊 (スカベンジャー)) is the 22nd episode of Toaru Kagaku no Railgun T. It was broadcast on September 4th 2020. The episode was directed by Sakurabi Katsushi, the screenplay written by Inotsume Shinichi, and storyboarded by Ohashi Yoshimitsu.

Mikoto is on the search for the truth behind the "soul creation" experiment, the study that creates two cyborgs from a single body. But before she could infiltrate the institution where the experiment took place, a mechanical "doppelganger" that looks exactly like Kuriba Ryouko had escaped the facility. After her firsthand encounter with Kuriba, Mikoto is informed of the hidden dangers involving the Doppelganger as well as how Kuriba created Indian Poker to resolve this problem.

Mikoto is still somehow not satisfied with Kuriba's explanation and decides to escort her. But, before they could part ways, the escaped Doppelganger appeared. And, at the same time, the Dark Side organization Scavenger launches an attack with the Doppelganger on their sights!
