Frieda had black hair going down to her shoulders and wide, blue eyes. Her ghostly garments are white, and there is sometimes a blue glow around her. As a ghost, she is also partially transparent.
Frieda, as a ghost, likes to scare unsuspecting students at the school. Her form as a ghost is off-putting to most, however, she is still friendly and down-to-earth.
When a group of students wander the school at night, Frieda prepares to scare them. She appears to Reiner Braun, before giving a creepy grin. She later sees Eren Jaeger on a stairwell and appears to him floating in a mirror. As he tries to convince himself he did not see anything, Frieda appears in front of him screaming, to Eren's horror.
Outside at the schoolyard, Frieda spots Christa Lenz and she sneaks up behind her to scare her. Before Frieda could proceed, she stops once she sees how upset Christa is, and instead asks what is wrong. Frieda then listens as Christa tells her about how she got separated from her friends.
Frieda tries to comfort Christa and says that she should not walk around late at night at the risk of becoming like her. Christa, unaware that Frieda is a ghost, says that she would not mind becoming like her. Frieda is shocked and horrified by this. She then hugs Christa and frantically tells her that she is fine the way she is and should stay that way, with Christa being oblivious to her urgency.
- Christa Lenz - Frieda quickly takes a liking to Christa, commenting on her cuteness and tells her to stay the way she is. When Christa is upset, Frieda tries to comfort her.
