Askin Nakk Le Vaar

is a Quincy and a member of the Wandenreich's Sternritter with the designation "D".

Appearance
Askin has medium length black hair, with a strand hanging down in front of his face, reaching his mouth. In addition to his Sternritter uniform, he wears an ornamental bracer on his left arm. He also has a thin face, with pronounced cheekbones and markings that run from the ends of his eyebrows, to the ends of his eyes.

Personality
Askin is very sarcastic, pointing out how Bazz-B states he is calm despite preparing to attack Jugram Haschwalth. He is also quite arrogant, questioning the intelligence of the scientists of Shinigami Research and Development Institute. He tries to trick his opponents, wanting Mayuri to pursue him into a trap. Also, by his admission, he isn't good at dealing with meticulous details and would rather quickly finish things.

The Thousand-Year Blood War arc
Upon receiving the orders of Yhwach, Askin and the other Sternritter gather at the Sun Gate before traveling to the Seireitei in order to participate in the conquest of Soul Society.

Following the meeting where Yhwach announces Uryū Ishida is to succeed him, Askin breaks up a confrontation between Jugram Haschwalth and Bazz-B. Insisting he helped them by preventing a fight from erupting, he cites Yhwach's dislike of fights and them having onlookers. Askin then says it would be bad for their positions, especially for Haschwalth.

During their second assault on Soul Society, Askin appears within the space where the Research and Development Institute used to be and explains to the researchers present how the Quincy had been hiding in the shadows for the past millennia. Surprised in turn by the appearance of Mayuri Kurotsuchi from within an invisible room, the Shinigami captain comments that Askin probably wants to verify their intelligence before leaving.

After analyzing Mayuri's appearance, Askin suddenly decides to leave, claiming that he doesn't want to spend the time trying different ways to kill Mayuri. He states that he isn't a detail-oriented person. He wonders why Mayuri isn't chasing after him, which Mayuri replies that he wants time to analyze his Reiatsu. Mayuri also hypothesizes that Askin wants him to follow him into his territory, to which Askin comments on how scary that deduction is. After sensing Suì-Fēng dealing a harsh blow to BG9, Askin comments that his majesty expected that the captains whose Bankai were stolen had mastered different ways to fight. He confirms Mayuri's suspicions that the captains were powerful, so the Sternritter were prepared for that.
