Anett Hosenfeld is a member of the GDR's 666th TSF Squadron, Schwarzesmarken. Her call sign is Schwarzesmarken 06. She suffers from PTSD, as a result of having her three best friends killed within 3 days of their first deployment. She despises Theodor because she believes that he abandoned her and her friends and left them to die during that battle.

As the only Type-77 blade user in the squadron, she was a straight girl and proficient in close combat. Her best friends' death mentally shocked her, but after overcoming her sadness and shell shock, she returned to the army.

Her parents suggested her that she should go to start kendou fencing training,so she went to a kendou fencing school everyday after class.This experience taught she how to use a sword and enforced her heart.
