Toaru Kagaku no Railgun T Episode 12

Exterior (外装代脳(エクステリア)) is the 12th episode of Toaru Kagaku no Railgun T. It was broadcast on April 17th 2020.

Kamijou's right hand was revealed to only have a temporary effect on Mikoto, who has transformed into a grotesque appearance. On the contrary, it caused Mikoto's form to change once again, her power growing as well. Those powers that continue to flow within Mikoto cannot be held back, but Kamijou and the others do everything they could to keep her at bay. Meanwhile, Kuroko confronted the puppet controlled by Kouzaku's ability. During this time, Uiharu and Saten successfully pinpointed the building where Kouzaku was actually located. Driven to a corner, Kouzaku lures Kuroko into her trap.

Gensei searches around Shokuhou's safehouse as he aims for the limiter release code for the Exterior. Shokuhou had set up several traps beforehand, hoping that it could hamper his movement, but Gensei paved his way through using the many esper abilities in his arsenal as a Multi-Skill. At the very last moment, Shokuhou uses a certain device and emerges with one final gamble!
