|I can't believe you drank all this. You're not young anymore. And I'd rather not spend my days changing your diapers.|
|— Anka to Dot Pyxis|
Anka is a young woman who has brown kempt hair, long enough to reach her neck, that is constantly tucked behind her ears. She also has light brownish-colored eyes. As a soldier, she is seen wearing the usual Garrison uniform.
Not much is known about her personality, however, as a soldier, Anka is shown to express little to no emotion, except for the moment when she learns of the gate breach in Trost District, which leaves her shocked, and when she learns that the plan to seal the gate was a success she shows surprise and relief. She seemingly follows orders without any objections, not questioning Pyxis for going with such an uncertain plan as using Eren Jaeger in his Titan form to seal the gate. However, she also understands the feelings of other soldiers and stated that there is a limit to how much one can be motivated by fear.
When the 104th Cadet Corps participates in a mock defense mission in Trost, Anka monitors the cadets' progress during the mission with Pyxis and Gustav. She later helps Gustav oversee the cooking contest that Pyxis is judging.
Anka appears in the residence of Lord Wald, accompanying Dot Pyxis along with Gustav. She watches as Pyxis plays chess, losing on purpose, seemingly to satisfy the Lord. At that moment, a soldier barges into the room, announcing that the gate in Trost District has been breached by the Colossal Titan, much to Anka's surprise. Despite Wald's protests, Pyxis readies to leave, followed by Anka and Gustav. Anka then goes on ahead, telling Pyxis that she will ready his horse and leaves.
Later, Anka arrives to the Trost District with other soldiers just in time for Pyxis to stop Kitz Woermann from killing Eren Jaeger. After Pyxis listens to Eren's words and gets him to help with plugging the Wall, Pyxis calls for staff officers to formulate a plan, Anka being one of them. While Pyxis announces the details of the upcoming plan to other soldiers, Armin Arlelt discusses the plan with Anka and Gustav. During the discussion, Anka states that Titans are not the only enemy, correctly deducing the current state of soldiers' mind.
During the operation, Anka, along with the other soldiers, watches the progress from top of the Wall. With Rico Brzenska firing a red smoke signal after Eren loses control, Anka proposes to pull the elite team back, but Pyxis refuses, trusting the elite team as they are the only chance for humanity. Once Eren regains the control and successfully plugs the Wall, Anka sees the signal and announces it to the rest of the soldiers.
Anka attends Eren Jaeger's trial along with Gustav at Pyxis' side.Erwin arrives to talk to Pyxis. Later, Anka is also by Pyxis' side when the Vanguard reports back that there is no breach as well as about the situation that occurred with Reiner and Bertholdt.
While not directly seen in action, it is presumed that Anka possesses enough skill as a soldier to be the escort of Dot Pyxis. However, her main focus seems to be strategizing, with Anka's intelligence being high enough to formulate a battle plan while quickly evaluating the situation and predicting further circumstances. A sign of her abilities may be that the original duty of strategizing was entrusted to only her and Gustav implying Pyxis trusts her enough to come up with a strategy that saves not only Trost, but humanity as well.
- Her first name refers to the name Anna, meaning 'Eagle', which among others is a symbolization of insight, intelligence and a sharp mind. It should also be noted that "Anna" is a name given to numerous Queens, being an interesting contrast to Gustav's name having a background of Kings.
- The word "Anka" is the Swedish word for 'Duck'.
