Leonhart family

The Reonhāto-ke (レオンハート家) is an elusive family living in a mysterious society beyond the Walls.

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 the Hometown. 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 their Hometown, awaiting his daughter's return.

Story
After the Hometown's attack on Shiganshina District, Annie Leonhart joins the 104th Training Corps under secret orders. When the time came for graduation, she participates in the Battle of Trost District. After graduating from her Training Corps, she joins the Military Police Brigade while her Hometown comrades Reiner Braun and Bertolt Hoover join with the Survey Corps. She later infiltrates the 57th Expedition beyond the Walls, devastating the mission as the Female Titan. A few days later, she is caught in Stohess District but crystallizes herself in a hardened skin shell, falling into stasis to prevent interrogation.
