Toaru Kagaku no Railgun T Episode 25

My Dear Friends (私の、大切な友達) is the 25th and final episode of Toaru Kagaku no Railgun T. It was broadcast on September 25th 2020. The episode was both directed and storyboarded by Nagai Tatsuyuki, and the screenplay written by Yasukawa Shogo.

With the secret of the "soul possession" exposed, Mikoto climbs the airship to confront the Doppelganger. Overcome by despair upon realizing that she was an existence born without a soul, the Doppelganger who spoke of taking revenge on humans attacks Mikoto through clones that she produced. However, Mikoto knows that the attacks are simply a bluff and she knew the Doppelganger's true objective. The Doppelganger rejects Mikoto's words and falls with the airship.

After the airship standoff, Kuriba is approached by the research facility chief. He, who was already downcast after hearing by Mikoto about the truth behind the Doppelganger, was told by Kuriba that the experiment can no longer continue.

Synopsis
After visiting Kuriba, Mikoto joins Kuroko, Saten and Uiharu outside. Saten jokingly invites them to a cafe known to be a venue of an urban legend, much to Kuroko's chagrin, but Mikoto does not mind going anywhere as long as they are together.
