Anka Rheinberger (Anime)

"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 Rheinberger (アンカ・ラインベルガー) is a member of the Garrison and one of Dot Pyxis' escorts, the other being Gustav.

Appearance
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.

Personality
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.

A Sudden Visitor: The Torturous Curse of Adolescence
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.

The Struggle for Trost arc
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.

Eve of the Counterattack arc
Anka attends Eren Jaeger's trial along with Gustav at Pyxis' side.

Clash of the Titans arc
Anka is seen on top of the Wall in Trost District during the supposed breach of Wall Rose. She wakes Pyxis up, scolding him for sleeping there and drinking alcohol, given his advanced age. She states that she does not want to be stuck taking care of him, much to the amusement of Pyxis, who says he would want nothing more than such a beauty doing so. Anka then reports to him that new Titans stopped appearing at the first and second lines of defense, but the search party only found a few as well. This makes them wonder about the situation, given the fact that if there was a breach, the amount of Titans appearing would be much higher. Anka then watches as 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.

The Uprising arc
Anka takes part in Pyxis's test to see if the current government truly cares about the well-being of the populace. At the conclusion of Erwin's trial for committing treason, Anka arrives in the King's throne room to report the false news of the breach at Wall Rose by the Colossal Titan and the Armored Titan. When the officials present respond by ordering that refugees from Wall Rose be barred from entering Sina, Anka departs to inform Dhalis Zachary of their reaction. After Zachary's forces take control of the throne room, Anka reports to them that the interior Military Police have been suppressed.

Abilities
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.

Trivia

 * 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'.
