Utopia District

The Utopia District (ユトピア区) is the northernmost district of Wall Rose. Little is known about it, since it has not been featured in the story yet.

Story
The Utopia District is briefly mentioned by Armin in the mission to rescue Eren from the Armored Titan. He tells Bertolt that Annie has been captured and that she's currently being tortured in the district's underground. This distracts Bertolt enough for Erwin to climb on the Armored Titan and slash him, freeing Eren.
