Waltrud Krupinski is a veteran ace of the 502nd Joint Fighter Wing, originating from Karlsland and attached with the Karsland Air Force. She is referred to as Earl and Countess by her friends.


Considered Karlsland's top veteran Ace, she joined JG52 at around the same time as Gertrud Barkhorn and Erica Hartmann, whom she considers good friends. She spent a good deal of time with Erica as her lead wingman. Among the 502nd JFW base, only Squadron Leader Rall has a higher confirmed kill count.

She was born in Domnau, in northeast Karlsland, and grew up in Braunsberg near the Baltic sea. Her parents are public officials, but because of her ability as a witch, she began to consider joining the military when she reached the appropriate age. She initially wanted to join the Navy as she grew up in a port city, because she could go to various countries. As a result of an inspection, she was found to be suitable to be an aviation witch, and she entered a training school for the Air Force. She was a bad example of a student who sneaked out of her dormitory with her friends to go to the the city at night and get into mischief. Despite her reckless behavior, her grades were excellent and she graduated as a Second Lieutenant.

She was assigned to JG52, but by that time the Hispanian campaign had ended and there was little opportunity to gain experience in combat. Instead of combat, she was trained by a senior sergeant who had battle experience in Hispania, and she gained sufficient flight experience by the time of the Neuroi attack. In the Ostmark defensive battle, she gained many takedowns and a lot of experience, but she also destroyed many Striker Units. It wasn't a problem unless supplies were low, but it became a major problem on the eastern front where supplies were routinely low, so it wasn't unusual to send her back to pick up supplies.

In one of her more famous episodes, on the day that Erica and Marseille transferred to JG52, Krupinski made an emergency landing, her striker unit wreathed in flames, right in front of a crowd of dumbfounded onlookers, only to turn around and greet the girl with a nonchalant handshake. On the other hand, the number of foes she manages to down to earn a totaled striker is considerable compared to any other medium scoring ace.

At one point, herself, Barkhorn, Hartmann and Johanna Wiese had an audience with the Emperor of Karlsland.

During Operation Bifrost, she was awarded with the Knight's Cross, was promoted to Flying officer and became the company commander of JG52 7th Company. The company took on defense and support duties in the east of Karlsland until the people withdrew, and after the withdrawal was completed, moved to Suomus with its units.

After this, she participated in Operation Barbarossa and achieved remarkable results. She was the second top ace of the unit, second only to Rall based on the number of shot down. She later became a member of the 502nd Joint Fighter Wing.

Because of the rather famous trio of herself, Nikka Edvardine Katajainen, and Kanno Naoe, the 502nd is often referred to by the nickname "The Break Witches." She isn't particularly worried by this, but she has taken a role to protect the younger two, who have trouble interacting with authority figures.

She was later awarded the Knight's Cross of the Iron Cross, but she was also injured by repeated crashes and later received the highest gold prize in the war wounds. However, she refused every time because she had only minor injuries, no matter how severe the crash.


Tall, slender, and elegant, she has earned the nickname "Countess"(伯爵 - Hakushaku). She is also a hard-drinking womanizer and a hedonist with an easygoing and optimist personality.

Brave and energetic. Despite her dauntless dog-fighting skill and sure marksmanship, her tendency to discard personal safety in favor of lining up for the attack rather than waiting means that she damages an unusually large number of Striker Unit, often making emergency landings under enemy fire.


Her inherent magic is called Magic Boost (マジックブースト, Majikkubūsuto). Releasing all her magical power at once, she can instantly get super acceleration, but it's rarely used as it places a heavy burden on the unit.


''Nipa, Nao, it's time to get to work! You don't want the Big Scary Teddybear to get mad and dock our pay again, eh?''






  • Waltrud is based off of Prussian-born German ace Walter Krupinski who, similar to Waltrud, was nicknamed Graf Pinski (Count Pinski) due to his Prussian origins. Krupinski was also one of the first to fly the Messerschmitt Me 262 jet fighter in combat as a member of Jagdverband 44 led by Adolf Galland, and was credited with 197 victories in 1,100 sorties.
  • As a canonical womanizer, Krupinski technically becomes among the first canonically openly homosexual characters in the franchise, whose sexuality is portrayed blatantly and not implied or depicted ambiguously. Chronologically she is the second such witch with this distinction, being second to Mika Ahonen. Of the two however, she seems to be the more generally well known.
  • One of the tallest witches along with Adriana Visconti, both being 1.75 m tall.
  • Implications are heavily implied in series and in art and tweets by Humikane, that she is in some sort of subtle relationship with Edytha Rossmann. During the events of the 502nd prequel light novel, Vesna Mikovič (who has romantic feelings for Waltrud) confronted her about who she loved the most, and Waltrud chose Edytha.
