Lest Karr is a high-ranking vampire noble and one of the Thirteen Progenitors in Seraph of the End. Calm, refined, and calculating, he maintains a cold demeanor and often masks his true intentions behind a polite smile. Despite his elegance, he harbors a deep sense of loyalty to the vampire cause and serves under Ferid Bathory, though their relationship is laced with mutual suspicion. Lest is a master manipulator, preferring strategy and political games over brute force. His presence always carries an air of danger, as he rarely acts without a hidden motive.
