Askin Nakk Le Vaar

Askin Nakk Le Vaar is a Quincy antagonist in Bleach, serving as one of the Sternritter (elite Quincy warriors) in the Wandenreich organization during the Thousand-Year Blood War arc. He holds the designation "D" — The Deathdealing, which lets him precisely calculate and manipulate lethal doses of any substance, turning virtually anything (even Reishi or oxygen) into a deadly poison against his opponents by adjusting toxicity levels.

He's a tall, slim man with slicked-back black hair (a single strand often falling over his face), lavender eyes, high cheekbones, and a distinctive laid-back, eccentric personality. Askin is calm, sarcastic, procrastinates fights when possible, avoids unnecessary effort, and often brings a casual or mocking tone to serious situations — sometimes even treating battles like minor inconveniences while enjoying trickery and traps. Later in the story, he's promoted to Yhwach's elite Schutzstaffel guard.
