Leonhart family

The Leonhart family (レオンハート家) is an Eldian family living under the rule of Marley in Liberio.

History
Annie Leonhart was trained by her father from a young age until the time came for her to partake in an attack on the Walls on behalf of Marley. Before she set out, Annie's father apologized to her and assured her that regardless of what the world thinks of her, she will always have her father on her side. He remained in Marley awaiting his daughter's return.

Shortly before the Battle of Shiganshina District, Bertolt remembers back to the Battle of Trost District, where Reiner had pressured Annie to take off Marco Bott's vertical maneuvering equipment, to prove that she and her father were different from the "evil race" within the Walls

Marley arc
Before the curtain's rise at Willy Tybur's production in Liberio, Mr. Leonhart speaks with Karina Braun, the latter praising Annie for having devoted her life to Marley. Mr. Leonhart refuses this, adamantly stating that she is alive, because she had promised to come home.
