Anka

Anka Rheinberger (アンカ・ラインベルガー) is a member of Stationary Guard and one of the Dot Pixis's escorts, the other being Gustav.

Appearance
Anka is a young petite woman. She sports brown kempt hair, long enough to reach her neck. As a soldier, she is seen wearing the usual uniform, consisting of a short light brown leather jacket with the badge of the Stationary Guard on both shoulders, on the front left pocket and on the center of the back, a light-colored shirt, a dark brown sash around the waist covering the hips, white pants and dark brown knee-high leather boots.

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 surprised. She seemingly follows orders without any objections, not questioning Pixis for going with such an uncertain plan as plugging the gate, however, she also understands the feelings of other soldiers, stating that there is a limit to how much one can be motivated by fear. At the same time, it was shown that Anka's behavior towards Pixis is not completely formal, as she woke her superior up by hitting him as well as saying that she does not want to be stuck taking care of him.

It's also possible she simply doesn't judge or treat people by mere rank nor appearance.She and Gustav were in charge of formulating the plan for the operation to stopper the hole when Armin shyly arrived and apologized for "butting in cause he is just a trainee" to which Anka replied that this does not matter which proved as an aiding attitude as Armin's plan was a key to save humanity.In the end, one might say Anka placing her trust into a trainee may be a factor of humanities victory.

Battle of Trost District arc
Anka appears in the residence of Lord Balto, accompanying Dot Pixis along with Gustav. She watches as Pixis 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 Colossal Titan, much to Anka's surprise. Despite Lord Balto's protests, Pixis readies to leave, followed by Anka and Gustav. Anka then goes on ahead, telling Pixis that she will ready his horse and leaves.

Later, Anka arrives to the Trost District with other soldiers just in time for Pixis to stop Verman from killing Eren. After Pixis listens to Eren's words and gets him to help with plugging the wall, Pixis calls for staff officers to formulate a plan, Anka being one of them. While Pixis announces the details of the upcoming plan to other soldiers, Armin discusses the plan with Anka and Gustav. During the discussion, Anka states that Titans aren't the only enemy, correctly deducing the current state of soldiers' mind.

During the operation, Anka, along with other soldiers, watches the progress from top of the wall. With Rico firing a red smoke signal after Eren loses control, Anka proposes to pull the elite team back, but Pixis refuses, trusting the elite team as they're the only chance for humanity. Once Eren regains the control and sucessfully plugs the wall, Anka sees the signal and announces it to the rest of the soldiers.

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 Pixis up, scolding him for sleeping there and drinking alcohol, given his advanced age. She states that she doesn't want to be stuck taking care of him, much to the amusement of Pixis, 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 Pixis. Later, Anka is also by Pixis' side when the Vanguard reports back that there is no breach as well as about the situation that occured with Reiner and Bertholdt.

Abilities
While not directly seen in action, it is presumed that Anka possesses enough skill as a soldier to be the escort of Dot Pixis. 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.

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.
